    Mosquitoes should be eliminated from the planet

    For

    • I will respond to his points in the same way he responded to my own. 1) What I mean by the statement that I made was that everything was made for a purpose. Like the pencil, it was made so that we have something to write with. Just think about everything in your surroundings.…
    • This topic is pretty straight foward. I believe that everything is created for a reason, a purpose, but I could not think of a single reason for some annoying insect like the mosquito to exist. In fact, instead of even benefiting society in any way, it passes diseases like West…

    Against

    • My opponent forfeited her third round, so all unanswered arguments from Round 2 are extended.
    • "What I mean by the statement that I made was that everything was made for a purpose. Like the pencil, it was made so that we have something to write with. Just think about everything in your surroundings. Every single one of them was designed to have a specific purpose that…

    The Tasmanian tiger should be cloned back to life

    For

    • this is my avert animal its a mamil no its not they have a dead pup
    • this is my avert animal its a mamil

    Against

    • Could you please spell properly? I have no idea what you just said. People won't vote for you if you don't care about proper grammar and spelling. I'll try to respond to what you said, and I'll try to translate for the audience, but I don't want to have to do this again."this…
    • It would be very difficult task to bring back an extinct species. And unless having the Tazmanian Tiger back brings any benefits, it would be a waste of money, which could alternatively be used towards creating new medicines, or even curing cancer. Just because it's your…

    Evolution is almost certainly true

    For

    • First of all, evolution is backed up by many discoveries and scientific papers. Here are two discoveries backing evolution: 1. Fossil Record The fossil record includes numerous fossils showing evolution. From tiktaalik to Australopithecus garhi, it is clear that evolution is a…
    • I think evolution has so much evidence, it's almost certainly true. My opponent, after accepting the debate, will put his reason why my statement is false. BOP is shared.

    Against

    • So let me get 1 thing straight you believe that out of the blue things just evolved into something great like what we see these days??
    • Yes I agree with that but where did it all start just magically the fossil came from the sky and the world was here already but how?Where and how did we all end up here with everything that we see?The fact is that God created the earth and many other things like monkeys which…

    Mosquitoes kill more people than sharks

    For

    • I, pro, will defend the position that mosquitos, do in fact, kill more people than sharks. Due to scientific studies, Mosquitoes kill 2 to 3 million people per yer, while infecting about 200 million people per year. My proof is proved in this wikipedia entry: A shark attack is…

    Against

    • On intelligence tests, we mosquitoes have found humans disappointing. In Flying Intelligence, humans scored particularly low scores; they don't even have the capacity to move off the ground. In Evasion Tactics Intelligence, humans utterly fail, as can be seen by their poor…
    • My opponent has forfeited this round. I will not add any new arguments this round, but will elaborate next round. Please recognize voters that forfeiting lowers the quality of this debate and wastes all of our time, in addition to being simply rude. We might want to consider…

    Evolution is consistent with scientific evidence

    For

    • Too bad.
    • Extend my arguments to the next round.

    Against

    • Jesus is love, just like Shrek. I'm a swagalicious atheist, but I will try to debate from this side (which I obviously don't agree with). Bananas are formed perfectly to your hand. That is obvious evidence. History is not open to scientific testing. Geologists, therefore,…

    The Earth is not flat

    For

    • It's called virtual reality cause It looks realistic. Also my bad, my brother was on my computer, never meant to create this argument. You win LOL
    • Your argument about that ice wall has quite a bit of flaws. How is it that some Arctic and Antarctic days and nights last for way longer than other days and nights? That part about you saying that the sun goes around the edge of the earth instead of above it? Then wouldn't that…

    Against

    • Okay, virtual reality, bad example, something else animated then. Your brother puts up a good argument by the way.
    • Genesis says that the Earth is suspended atop pillars. You saying that the ancient civilizations were crazy is bias and has offers no support to your argument after all in the future we'll be the crazy ones. I never said most flat-Earthers are Christian, so the Vatican can have…

    Humans should be classified as animals

    For

    • FINAL REBUTTALS"..How are we different? ..I believe I have already answered that.."Actually, NO, you haven't!!!Everything you have offered can be seen in other animals! I have even given and offered actual video documentation refuting every claim you have made!The reason why…
    • Rebuttals: "..but we have evolved past animals.." Exactly HOW?! Again, how can we still use tissues and organs from other animals in life saving procedures then? How can we still contract infectious diseases in our tissues and bodies of organs that come from other animals? We…

    Against

    • You seem to equate more evolved to superior. I made no such distinction. Therefore there is no contradiction. I believe we are more evolved. Comparing those two pictures proves it. Only humans can grasp abstract art. The reason I believe animals superior to humans is that they…
    • How are we different? I believe I have already answered that. Animals have intelligence, but not as evolved as ours. Animals have morals, but not as evolved as ours. Compair the painting by the elephant to a painting by Davinci. Yes we have animal instincts and some organs can…

    Monkeys have intelligence similar to humans

    For

    • My apologies for not using any sources. It's hard to find some. I hope you can tolerate. For start, the physical traits you've mentioned (limb size, feet...etc.) have little to do with intelligence even though the traits are distinguished. The 5 million year span follows the…
    • I've decided to choose on the topic that if monkeys have similar intelligence to humans. It sounds trivial, but I think it can be fun, and I would like to point out that this is NOT a serious debate. Good luck if you decide to participate. I will be arguing pro. Definitions:…

    Against

    • Sure, humans and other apes are closely related, as we evolved in similar environments, and thus we have many similarities. This does not mean, however, that we are intelligent in similar ways overall. For starters, empathy is found in lions[1], tool use is found in…
    • As a first point, I would like to point out that while humans and other monkeys have a common ancestor, that was at least 5 million years ago and possibly longer. [1] During this time, we have diverged to the point where not only are we and chimpanzees different species, but,…

    The United States should send a manned spacecraft to the moon

    For

    • Con has responded this time perfectly, yet he has chosen to re-explain the same point he has been using since the beginning. Unfortunately for Con, this means that he wont be able to rebuttle again as this is the last round. Con has not produced any other arguement other than…
    • I happen to find your latest response extremely dull and it was not backed up with evidence to support your claim still. Until you can provide evidence, your latest claim is not yet valid and i am still in the lead of the debate as i have producedPointEvidenceExplanation yet a…

    Against

    • Point: A manned spacecraft to the moon would be unreasonable due to costs and efficiency Evidence: Cost of Mars rover : approx. 820, million(Keep in mind mars is significantly further away from earth than the Moon, which would reduce both fuel and time to arrive to the Moon.)…
    • I find your use of "stupidly" very unprofessional. I apologize for my inaccuracy on the price, however, the price of a manned spacecraft STILL exceeds the price of a robot. A robot could last for years on a planet, yet a human could last a very short time.

    Humans are not alone in the universe

    For

    • I acknowledge the flaws of my argument, but I shall point out yours: You wrote, " It has never been reported that carbon, oxygen, and the other essentials that we need for life have ever been found on other planets. " That is completely untrue. Our neighbor planet, Mars, has…
    • The Universe holds uncountable planets and stars. There are seemingly infinite realms and worlds, and galaxies and solar systems. The cosmos is addressed with many questions: Questions of origin, questions of fate, questions of destiny among many others. The vast space of our…

    Against

    • ResponsesResponse 1" You wrote, " It has never been reported that carbon, oxygen, and the other essentials that we need for life have ever been found on other planets. " That is completely untrue. Our neighbor planet, Mars, has trace amounts of oxygen in its atmosphere. Carbon…
    • Here we goLets review the resolution at hand. My adversary is claiming"We(humans) are not alone"and clearly is directing this at aliens and other sorts of human like creatures. We can tell this during his R1 and R2 statements"We are not alone. Humans are most certainly not the…

    Salamanders make better pets than fish

    For

    • No the Salamander, is better even though it's not a common pet it's still better than a pet fish. can you put out your hand to feed a fish? No you can't. Can you do that with a Salamander? Ding Ding Ding yes you can. So therefore a salamander is better than the common household…
    • Yes Salamanders are better than fish. Why? You can actually hold them and feed them yourself not just put some food in the water and watch them pick at it.

    Against

    • cool aid attic arent you. well fish is better unless you don't have common sense. go ahead and start catching salamanders to eat. That will make you more of a knuckle head. you cant survive off a salamander.
    • you been drinking cool aid sir. 1. can you eat salamander? 2. can you fry salamander? 3. can you really have salamander as a common pet? 4. can salamander be considered sea food? 5. can you really see salamander as anything special to a aquarium? The answer to all these…

    Sasquatch does not exist

    For

    • My opponent says, "the amount of evidence required to convince skeptics is huge". Who cares what skeptics think? The only people that need to be convinced that Bigfoot exists are the scientists that can determine whether they exist or not. The skeptics decision can then be made…
    • My opponent says that Bigfoot has not gone unnoticed and has been sighted many times. It is true that many Sasquatch sightings have taken place (a few thousand in America over roughly one hundred years). This high number of reported sightings often gives Bigfoot believers a…

    Against

    • My opponent claims I must only convince scientists not skeptics, but scientists are skeptics. My opponent suggests people could chase after a Bigfoot that they find. But that is a very dangerous thing to do as Bigfoot is much stronger than people and chasing after him would put…
    • "If thousands of people have seen Bigfoot, then why have not one of these people managed to get solid evidence of their sightings." The answer is because the amount of evidence required to convince skeptics is huge. For my opponent"s rejection to my FBI"s most wanted evidence,…

    Loch Ness Monster and other monsters should be considered real

    For

    • The Lochness Monster is a cryptid that reputedly inhabits Lochness, a lake in the Scottish Highlands. It is similar to other supposed lake monsters in Scotland and elsewhere, though its description varies from one account to the next, with most describing it as large. Nessie…
    • Ahhh... my opponent lacks belief of God"s creation. We don"t necessarily if know if God didn"t create Nessie. Up to two thirds of the plant and animal species in the world's oceans may be undiscovered, according to the largest study of the oceans' biodiversity ever conducted.…

    Against

    • God's creation I'm not really sure why you brought this up. This isn't a debate on beliefs around religion. You could've said it was already existing but I don't think you should bring god into this so I choose to drop this argument You used conditionality which is unfair.…
    • Once again, my opponent usd quotes but had no link to their evidence, let alone where he found it. I'm aware that people have claimed many sightings of the Loch Ness monster. I'm here to prove that what they saw is not the Loch Ness monster. Nessie was made in Scotland as an…

    • groovy
    • :| some people are unbelieveably sad....get a life its a joke..do you have nothing better to do with your time im sick of everyone on here getting so self-righteous. stuff the lot of you :)

    Against

    • This is an owl trying to think: http://www.cuterush.com... They clearly are not smart.
    • My opponent provides a definition of 'smart' as 'showing mental alertness and calculation and resourcefulness' which I'm fine with using, but she never really shows how owls meet this definition. My opponent contradicts herself, saying that being nocturnal is smart, bu that…

    Time travel to the past is possible

    For

    • K then.
    • Well your so called formula only applies in physics which is a joke! I only studied the finest classes in troll physics while getting my trollology degree. You say trollology doesn't exist, HOW DARE YOU! Trollology is a very respected ology. I even have proof of my PhD in…

    Against

    • Thanks for the the clarification on my formula. By fixing this equation you proved yourself that time travel isn't possible. Trollology? That doesn't exist. You must be on shrooms and crack to hallucinate this form of science. I have three PhDs in zoology and I know that zebra…
    • First of all, I'm a genius in physics and space. I have 3 PhDs in zoology. Spinning on the North or south pole won't send you back in time. Yes, The North and South poles have strong magnetic fields, but no UFO time machines. You want to speak mathematically huh? Well, 2 times…

    The Earth's shape is not what we are taught

    For

    • Firstly, id like to make it apparent my opponent has a personal vendetta against me for an obvious truth i pointed out in a previous debate. Which i couldn't be more happy about, as it will make for better debating. I could with no effort show you 1000s of instances that…
    • I put forth the heliocentric model put forth by modern science in no way accurately describes the terrain on which we live.

    Against

    • The first 90% of your argument was from a source that is a blog. This blog cannot be counted as a credible source. Please show me a more credible source and then I will refute your claims. You said that "95% of internet traffic is directed via submarine optic cable." But you…
    • I am arguing that yes, the earth and the planets revolve around the sun. Looking forward to the debate.

    Lions are better than cheetahs

    For

    • Touch" I do admit you have got the upper hand here. BUT, I will try to counteract your statements again. About the fact that you said lions sleep an average of 20 hours a day. I looked into that fact and I found that only some parts of it are true. mostly male lions sleep an…
    • Yes I do believe that cheetahs are quite faster than lions but know this! Lions are bloody majestic. Of course, that statement seems a bit of a baseless one, here are my opinions.: - A lion's roar is just one hell of a terrifying and menacing sound, It's loud, deep and…

    Against

    • Cheetahs are the fastest animals on earth, that's one fact that most people know. but did you know that there is more to the cheetahs than speed? . For one, they hunt during the day, so they avoid direct competition from leopards and lions. that proves that there smart.second…
    • cheetahs are faster and sleeker than lions. they are also better adapt to keep out the sun

    Gravity is not a fundamental force of nature

    For

    • What is this stupid pedantry? I clearly STATED that our version of gravity is false by deducing it logically. And I rebutted your big paragraph with the statement "The moon has no velocity because I don't see it move". I'm sorry for not clarifying that statement.
    • I believe in a form of gravity, just not the one that is defined by science, hence "therefore, BY OUR DEFINITION, gravity is false". The moon doesn't have any velocity. That's why I don't see it move.

    Against

    • My opponent has claimed that the moon has no velocity because "I don't see it move". However he has produced no evidence to support this claim. The moon moves at 2,288 miles per hour (3,683 kilometers per hour) around the Earth http://coolcosmos.ipac.caltech.edu...- By my…
    • I would like to point out the fact that the Pro never clarified "Our Definition of Gravity" is false. He is simply avoided my argument by making an unjustified statement. In his first speech he specifically said that gravity is not real, not one but three times. Voters please…

    Carcharodontosaurs were the most powerful dinosaurs

    For

    • The Carcharodontosaurs were more than likely the most powerful dinosaurs to ever exist. While they did go extinct before the reign of the Tyrannosaurs, they still had the opportunity to show how powerful they were. They ruled the entire world in their different species being…

    The Moon should be colonized

    For

    • I have no further arguments. Con refuses to realize the benefits of a colony on the moon.
    • The moon should be colonized becauseIt would give us more space to stop overcrowdingThere is about 7 billion peple on earth and not enough space or resourcesNew things would probably be discovered which could lead to advancements in technology, medicine, etc...It would make…

    Against

    • "It would give us more space to stop overcrowdingThere is about 7 billion peple on earth and not enough space or resources"There is still plenty of undevelped land on Earth. We would be better off finding ways to develop it. The resources found on Erth are not available on the…

    The United States should explore space

    For

    • Thanks for the response. What I mean by exploring is to use astronomy, space technology, and machines to explore and go out there. Observatories are included. Refutation 1. "Creating ships and shuttles with our limited technological knowledge is in fact a waste of money, we…
    • :) I agree to those definitions. Refutation 1. "There is no reason for the United States to explore space or fund organizations that explore space (besides the search for habitable planets, which I shall cover later on in the debate. " Is that not a very good reason to explore…

    Against

    • My opponent is using the term "exploration" incorrectly, since this is a debate he should have clarified earlier or used correct terms. 1.) My opponent is being a bit over dramatic, claiming that we are running out of time. He fails to realise that our society lives in the face…
    • Before spreading the jam onto the peanut butter of this PB&J, I shall define explore. I will use this previous debate as a lesson: . http://www.debate.org... First off, we cannot go into space and literally explore it. .. You use the term loosely as chuck_norris did in the…

    Space exploration's benefits outweigh its disadvantages

    For

    • I extend my arguments.
    • I will now begin my argument. Argument-1) As we know, the world's resources are finite. Mining on earth is also dangerous to the environment, as it can cause deforestation, water pollution, and erosion. [1] However, why only mine on earth, when there better opportunities in…

    Fire is not a living thing

    For

    • This has been an all around strange display on my opponents part. My opponent has not countered my argument, nor provide any facts towards a counterargument. My opponent is in congruence with my point of view, that is, he explicitly agreed with my point of view and admitted he…
    • My primitive opponent has stated "concede point" and "according to "science", fire not alive." He agrees with me, thus proving him wrong. My prior facts extend foreword into the final round.

    • Ug no find "concede" button. Ug suggest install java plug-in.

    Paranormal energy, such as ghosts, is real

    For

    • You basically repeated everything you said in round 1. Also, you have proved irrational and fallaciously stubborn in your arguments. Also, you seem closed to new suggestions, which is not a characteristic to be proud of in anyone. You have not grasped the definition of "ghost"…
    • I thank CON for his so far good argument, even though it presses the bounds of the word "fallacious." 1.)Yes, I agree with your second paragraph: "For quite a long time, indeed, the Doctrine of Humors was the prevailing wisdom in medicine, the Flat Earth in Geology, and…

    Against

    • Unfortunately, the debate has come to a premature end.

    The Big Bang is the most accurate account of the universe's origin

    For

    • Rules 1. Con will argue in favor of the resolution that the Big Bang indeed, did not occur. 2. No trolling. 3. Do not plagiarize. 4. Con may argue first, but must type "No arguments shall be made, as agreed upon" for R5. Failure to follow these rules will result in a 7-point…

    Astronomy is the most interesting science

    For

    • My opponent fails to observe the true purpose of this argument. The point is not astronomy's production, but fascinating properties. Astronomy, by a definition from dictionary.com, means the science that deals with the material universe beyond the earth's atmosphere. If you did…
    • My opponent claims that I overuse opinions. To clarify, let me assert: What is the most interesting to someone personally IS their opinion. You may criticize my use of such in my argument, but when you start an argument, it is difficult to decide which facts to prove or…

    Against

    • I will go over this step by step. "There are many unexplored areas in it, so we still have much to learn, and it may produce outstanding results when we do make discoveries in that area." pro 1 "The point is not astronomy's production, but fascinating properties. " pro 3 1) I…

    Time travel to the past is physically possible

    For

    • Just because we can't go into the past, doesn't mean we can't time travel. Con says for any significant time dilation only occurs at speeds close to the speed of light. But time travel does not have to be a year into the future, or even a day. As I have already shown, someone…
    • Time travel is possible and what's more, its already been done. Sergei Krikalev is known as the greatest time traveler in human history. This Russian cosmonaut holds the record for the most time spent orbiting Earth. A total of 803 days , 9 hours, and 39 minutes. During his…

    Against

    • If you use time travel to mean the passing of time, then technically we are travelling through time right now. That is not what the the term "time travel" describes. You have purposely misrepresented the concept of time travel by misinterpreting the term "time travel" to mean…
    • Any significant time dillation only occurs at speeds close to the speed of light. Accomplishing this requires extraordinary amounts of energy which is impossible for humans to supply. It is impossible according to current physics to move backwards in time. Therefore time travel…

    Faster-than-light travel is possible

    • Arguments 1. Impact on culture I did NOT dropped my point about impact on culture. I just didn't state it in my last argument. In fact, Bigfoot had had demonstrable impact as a popular culture phenomenon that led to a law regarding Bigfoot in 1969 declaring that "any willful,…

    The periodic table should contain more undiscovered elements

    For

    • This debate was clearly worded incorrectly and as a newbie, I would like to shut it down. But, my reply to your round would be "But...science"

    • I apologize about my last post. I meant to say elements and not arguments but I updated the post from my phone and it was auto-corrected. In any case I'm 100% sure that Pro has no ground in this debate. Because of the way he worded his claim all I have to do is to prove that…

    Woolly mammoths should be brought back from extinction

    For

    • yes, but it would be better to have a live one to study.
    • woolly mammoths are awesome, and we could learn a lot about ancient species from being able to study a living woolly mammoth.

    Against

    • Wooly mammoths may be cool, but they would be a hazard. They are large animals(larger than elephants) even thought it would be a scientific outbreak but we can still use dna from frozen/dead woolly mammoths to finish the research.
    • We shouldnt because they could be a danger to our civilization

    Avocados are botanically fruits, not vegetables

    For

    • This is a heated discussion between me and my friends my value for this debate is fruitalicious my criterion is fruiting avocado refers to the fruit (technically a large berry) of the tree that contains a pit (hard seed casing) which may be egg-shaped or spherical. Avocados are…
    • Ok my opponent says that the culinary point of view is the general view on an avocado, he says . Well let me show you. First if we look throughout his case at the places where he got his definitions then we must see that these sites must have taken a while o find. I did my own…

    Against

    • It's been a privilege to explore deeply an issue that, on the surface, seems straight forward. I hope I've shown that this issue, like so many others, is not black and white. < > I assume my opponent means to bring this up in support of his claim that my sources are less…
    • Thanks again to my opponent for continuing this dialog despite the fact that one commenter considers it to be spam. I am not engaging in semantical debate. Instead, I am arguing on the grounds that classification of objects is not unique to one area of life and that the…

    Zero should be classified as an even number

    For

    • Here is the long awaited rebuttal."The burden I accept in this debate is to show that Zero is not an even number." Agreed.To make it easier to read my rebuttal, I will put quotes in Italics as well as in quotations, and my refutations in bold.Rebuttal1. "seems that zero has its…
    • Let's get started! I will go about arguing by first reviewing what defines an even number, then comparing these attributes to the attributes of zero. WHAT IS AN EVEN NUMBER? Good Question! An even number is most obviously divisible by two, but it shares many other unique…

    Against

    • I really have nothing further to add. Extend all my arguments; vote Con!-C.
    • I want to place this here, the first thing you will see when reading my argument:Zero does not have two as a factor; it cannot be expressed as a multiple of two. EVERY EVEN NUMBER DOES AND CAN.It is the most basic element of even numbers, that every single one of them can be…

    Against

    • Since you did not specify what kind of "Lucid dreaming", I will. "Lucid: Expressed clearly. Easy to understand". Although there are more definitions, I'm going with that one. "Dreaming: a series of thoughts, images, and sensations occurring in a person's mind during sleep."…
    • When I said you were making stuff up, I didn't mean it like that. The Lucid Dreaming you're talking about, I totally agree with it. It's just I was confused on which kind you were talking about because you didn't specify, so I did myself, but after that you re-specified. That's…

    Dinosaurs and humans coexisted

    For

    • I don't even have to use the Bible to give evidence for the flood. First of all, a flash flood can produce a large layer of rock sedimentation in a few hours, it doesn't take millions of years. If you took a jar of water, sand, rock, soil, and other types of dirt and shook it…
    • "It is possible, through radiometric dating, to know if the skeleton of something had died 65 MILLION (not billion) years ago. [1] While we may not know if one male dinosaur liked pretty butterflys and rainbows, but had to keep it secret from other dinosaurs for they wouldn't…

    Against

    • "For example, the Karoo formation fossil field in Africa contains eight billion vertebrate fossils." In no legitimate source, does anyone say that there are 8 billion fossils there, and only one mentions a massive amount (800 billion) but then goes to say, it's less like 40,000…
    • "Okay, when you say this, you assume that that is actually how they do it though. Its not. Even if they did, radiometric dating is not perfect. I have actually talked to people who use it and they say that it is a good method, but there is much room for human error." Although…

    Flat-earth theory deserves no serious consideration

    For

    • These are almost the exact same arguments I've heard from those Russians. If the Earth is flat then how come we have day and night? The light of the sun would always hit the Earth's surface. If the Sun hides behind the edge of the Earth then why can't you show me a photo of the…
    • I've recently visited Russia and was surprised as to how many Flat-Earthers there are. So I have decided to see some of the arguments that people have to prove to me that the Earth is flat. First of all, Eratosthenes proved that the surface of the Earth is curved more than 2000…

    Against

    • "If the Earth is flat then how come we have day and night? " With a small, close sun, the light is shed locally. Perspective causes the sun to disappear from sight. "why can't you show me a photo of the Earth's edge? "The sun does not hide behind any edge. There may not even be…

    Gravity is the strongest force in the universe

    For

    • Power, has everything to do with it. Gravity is by far the most powerful force. I do not say this because gravity is the most common and well known force in the universe. I say this because it is the truth. In this analogy, gravity is a fire ant, and the strong force is the…
    • In your statement you opened things off by stating that in my first statement I contradicted myself. You stated that I said that the strong force was the strongest force in the universe, even though earlier in my statement I had said I was supporting gravity. I would like to…

    Against

    • "Your" analogy (which you most likely got from http://tinyurl.com...) about an ant and the fattest man in the world is false. A proper analogy would require the ant to represent Strong Nuclear, and the fattest man to be Gravity. Gravity exists on a much larger scale than Strong…
    • "Powerful - Having or capable of exerting power" "Power - Strength or force exerted or capable of being exerted; might." (Source: http://www.thefreedictionary.com...) Power, raw power, has nothing to do with the way it affects us. I agree, gravity is a crucial force in the…

    The United States should fully adopt the metric system

    For

    • Con fails to refute the original reasons used to defend the metric system that I have provided. This is not exactly a minor point, since the entire foundation of the metric system stands on them. As for Decimal Time, there are 2 reasons that explain why it was rejected:1)…
    • [1] Measurement unities were so chaotic in Europe, that each city had different systems. Several people through history have supported the creation of a unified system. [1][2][3] Con cites the failure of decimal time as an argument against the metric system, however, decimal…

    Against

    • I would expect awareness of the change in the meter, and gram, to be common knowledge. After all it was the 0.2 micrometer difference in the platinum bars used in the 1886 standard that prompted the need to create a more definitive standard[8]. At least the meter had a fix by…
    • I don't expect my opponent, or the audience to have a full grasp of French history. Any irrefutable proof would be in French, and I don't expect everyone to know French. Perhaps a book from when people were trying to convince the US to go metric that cites "pure reason"[6], but…

    Zombie fungus is exaggerated in popular media

    For

    • My opponent is still confused about what the debate is about. This is due to his lack of debating skills and experience. He has wasted 4 rounds of debate in trying to establish what the topic is about and has made many false assumptions. Then he goes on to state that my first…

    Against

    • I DISSAGREE! However, I have an open mind and I am ready to be proven wrong. Ok, anyway, as far as I have seen, the fungus is not literally able to control the ants body. However, it is able to introduce chemicals to the ants brain that makes it do what it wants. Their are many…

    Wet grass is evidence that it rained

    For

    • Then you concede, "Wet grass is evidence it rained".
    • Affixing words like "Solid", or "Concrete" in front of the word evidence doesn't change the meaning of evidence, those words are adjectives elaborating the magnitude by which the evidence supports a conclusion. You said, "...but it's still a clue.." Clue is defined as a piece…

    Against

    • No, wet grass is evidence that it MOST LIKELY rained. see, there are many other possibilities of why there is wet grass on a large area. Maybe a tsunami hit recently? Maybe a massive flooding that lasted days finally went away and all the grass is wet? Yes, it can point to it…
    • Now keep in mind that i may misuse words because of laziness or use slang. So yes, Wet grass is technically evidence that it is likely that it rained.

    Against

    • Observation 1 and Contention 2 (the money argument is also covered): 1) My opponent seems to be priding himself with the best possible for space exploration. He has gone all out toward the idea that telescopes can be accomplished, but you must examine all aspects of the…
    • Observation 1--> 1) I have not agreed with your case There are 2 types of exploring (as far as this round goes)… telescopes, and physical. Within this debate, however, you have to see that the resolution specifies the future tense when it states the phrase "should be pursued."…

    Governments should keep funding efforts to contact extraterrestrial life

    For

    • The knowledge and technology to be gained from interaction with extraterrestrials is potentially limitless:
    • Humanity in many ways defines itself through exploration, and the search for alien life is part of mankind's exploration of the Universe:

    Against

    • Attempts to contact extraterrestrial life are a waste of time and money:
    • Contact with an extraterrestrial civilization more advanced than our own could lead to mass existential crises, putting the existence of human civilization at risk:

    Intelligent alien life exists elsewhere in the universe

    • I did support my reasons for my statement that I have made. I don't think you read correctly.
    • No one has evidence that proves aliens exist or not. But I feel aliens does not exist. Yes, there are photos of Mars that looks like aliens are there. But the photos could be photoshopped. Especially, with the technology we have today. You can create any photo, or website. Yes,…

    • You said, "I did support my reasons for my statement that I have made. I don't think you read correctly." I did, in fact, respond to the reasons you put forth.Given that you haven't advanced any new arguments, or attempted to rebut my replies, I don't have much of anything to…
    • Well, it seems as if we may not need all the rounds of this debate after all. You began this debate with the claim that 'aliens do not exist.' You then began your argument with the statement, "No one has evidence that proves aliens exist or not." In light of that I would…
