lol but you guys got to admit that the aliens are pretty ugly but area51 was a pretty game though..
? If we've seen aliens then this wouldn't really be a debate... We don't know what aliens look like. Also, Area 51 isn't just a game, it's a place.
But back on topic, if you think about it, extraterrestrials must exist. We have so many planets in our universe, that to think we are the only living beings would be incredibly ignorant.
According to Stephen Hawking, with as many planets as there are in the solar system, it is not all that big of a stretch to believe that every conceivable combination of particles that can form life have already been created. As in there is practically an infinite amount of life forms that are slightly off from each other. (Stephen Hawking explains it better) I don't see this as that big of a stretch, personally.
