Extraterrestrial Life Must Exist in an Infinite Universe

Let's look first to my opponents observation: "In order for my opponent to win, me must PROVE that extraterrestrial life MUST exist in an infinite universe. " I agree. That is the resolution, that is what I intend to prove. "For the sake of the debate, I will agree [that the universe is infinite]. Sure. " Great. Let's begin! --REBUTTAL-- My opponent's key objection to my argument is that not every possibility has to exist: that is, simply because things are possible doesn't mean that they are real and do in fact occur. He states: "My opponent makes the mistake of saying that because something is possible it is reality. Read his statement again. He claims that since life is possible, it exists. " My opponent is correct that on Earth, even if something is possible, it is by no means a certainty. But, in an infinite universe, if something is possible, it is certain to occur or exist somewhere, on some planet. Let's look at the situation logically: When there are five possible choices of candy inside a hat, and a trick-or-treater picks out two of these pieces, two of the five possibilities become reality. Similarly, let's imagine every possibility for what can exist (very close to if not equal to infinity, only restricted by the laws of reality) as held inside a giant hat. Because there are an infinite number of planets (something my opponent and I agree on), we can imagine that it is as if a trick-or-treater has reached into the hat and picked out a piece of candy an infinite number of times. Each possible planet/type of candy in the hat is a possibility, and each real planet/piece of candy chosen is a reality. This number is infinite: logically, every possibility must exist when there are an infinite number of them and an infinite number of places in which they can be brought to fruition. -- "Think about this: It is possible that I will be killed tomorrow by a resurrected Viking that flew to my house on the back of a zombie whale. Is that possible? As far as we know, yes. Does that mean it will happen somewhere in an infinite universe? Well, that is for you to decide. " It is true that his "viking-zombie whale-murder" scenario seems extremely unlikely to occur. But my opponent is falling into the trap of looking at our Earth as a closed system. He is ignoring the rest of the universe, an expanse that is, quite truly, infinite. Therefore, one of the infinite planets out there must be exactly like Earth - except for the fact that my opponent will be unfortunately unable to finish this debate, due to a most ill-fated encounter with a zombie whale-riding resurrected viking. Just because it will not necessarily occur on our Earth does not mean that it will not occur on another of the infinite planets that exist. --SUMMARY-- My opponents argument rests on the idea that the possibility to exist does not guarantee existence. While this may be true in a closed environment like our Earth, it is most certainly true in an infinite universe. This is due to the laws of probability, as I proved this round through a logical thought experiment. In an infinite universe, every possibility that can exist within the laws of reality must exist. Because life can absolutely exist within these parameters, life must exist on countless planets besides our Earth. This robustly proves the resolution. For all of these reasons, please join me in voting Affirmative. Thank you and good luck to my opponent.
