It is possible that a flying pink unicorn exists

Thank you for accepting. This should be a very interesting debate.I would first like to let the viewers know I chose a flying pink unicorn almost randomly. Any object that probably did not exist would do, but the first bizarre unlikely thing that came into my head was a flying pink unicorn. Thus none of the attributes were specifically chosen for any particular reason other than that it helped make my point when I was arguing in another debates comments section. [1] Just thought I'd make that clear. :)First of all let me lay out some foundations of what we are actually arguing. Possibility - Being within the limits of ability, capacity, or realization I.) My opponent has already gratefully accepted this definition. But what does it really mean? Well if I were to say the chances of ___ are ____. That means that it is a possibility. In other words if there is a chance of something happening or existing; no matter how low or miniscule that chance is, it is a possibility. So if the chances of me being Osama Bin Laden are 1.5 million to 1, it is still possible that I am Osama Bin Laden. Just very highly and unreasonably unlikely. Even if the chances of something is 999,999,999,999 followed by a 1,000 zeros, to 1, it is still possible. For if it was not possible than it would be impossible, and anything that is impossible obviously does not have any chance of happening. Therefore my opponent will have to argue that the chances of there being a flying pink unicorn is absolutely zero. I hope my opponent and all the viewers agree on that. Now let's get down to the grit of it.II.) There is the question of whether impossibility even exists. Through the use of paradoxes you might be able to make an argument that impossibility does exist. But seeing as I don't need to prove there is no such thing as impossibility I won't completely go there. However if my opponent makes a good enough argument I may be committed to, though I do not see how a flying pink unicorn could be paradoxical. If my opponent could make a strong enough case to show that a flying pink unicorn is paradoxical (although I don't see how he could), I have a rebuttal awaiting that I think would be interesting enough. I will contend that when speaking literally we can very few times seriously say anything is impossible. In fact we can only really argue about probabilities. Most likely everyone would agree that there is probably no such thing as a flying pink unicorn (except thett who has seen one apparently), but probably most people would agree that there is a possibility that one exists. Although it isn't completely necessary, I will submit a few illustrations that make it possible for a flying pink unicorn to exist. My opponent will have to prove that there is zero chance of any of them actually being true. I will submit the fact that all of the following are unlikely, but I would like to stress that the likelyhood of these events is irrelevant. III.) 1. Let's go back to one thing I mentioned earlier. Thett3, in the comments section of this debate, said that he has seen one! Quote>"The flying pink unicorn exists, I have seen it!" <EndQuote. At first you would say, "he must have been joking." But do we really know that? I hear you say "then he must have been lying to try to mess with us, I mean it is Thett we're talking about!" But can we really know? "Then", you say, "if he's not joking or lying he would have to be crazy. That would explain allot!" But we can't know any of this? It is possible that Thett wasn't lying, joking or crazy, and therefore it's possible one exists. While it isn't probable, it is possible. (Sorry for the swipes thett. I couldn't resist ^_-)Therefore to refute this my opponent would to prove the following.1. There is no possibility that thett was not lying.2. There is no possibility that thett was not joking.3. There is no possibility that thett is not crazy, and thus did not imagine it.IV.) 2. My second illustration, which I believe is even stronger than the first, is as follows. There are arguments that the universe is infinite. My opponent will I hope, concede the fact that the universe might be infinite. If the universe is infinite, as we will assume it is for now, that means there is an infinite amount of planets. An infinite amount of planets would mean an infinite possibility of life forms. An infinite possibility of life forms includes a flying pink unicorn. Syllogismised (yes I know that's not a proper word, but it should be!), it would be like this. 1. There is a possibility of the universe being infinite.2. An infinite universe would mean an infinite amount of planets.3. An infinite amount of planets would mean an infinite amount of possible lifeforms.4. An infinite amount of possible life forms would include a flying pink unicorn.5. It is possible that a flying pink unicorn exists. Defense of premises1. There are scientific and philosophical arguments that points to the fact that the universe might be infinite.[2][3]. Polls also suggest a large amount of people believe it to be so. [4] Therefore it is possibly infinite. 2. This makes perfect sense. The universe is made up of planets stars and other objects. If the universe is infinite than there would have to be an unlimited amount of stars and planets, no matter how mind boggling that might be.3. This also makes perfect sense. Earth has life forms on it, thus we must assume there must be life forms on some other planets. Since the amount of planets might be infinite the amount of possible life forms might also be infinite.4. This is undeniable I think. A flying pink unicorn is a life form therefore it would have to be included in a list of possible life forms.5. This conclusion follows from the premises, meaning that the argument is valid. The conclusion is logical, and proven, meaning that the argument is sound. If there is an infinite amount of possible life forms, and if a flying pink unicorn is a life form, than there is possibly a flying pink unicorn in existence. I have shown my argument to be both valid and sound, thus proving that a flying pink unicorn possibly exists. Well that was fun! I look forward to my opponents contentions and rebuttals.
