Favorite President ever!

Well yeah, Aliens exist, but we don't have any proof we have had contact with them.

It's plainly obvious by pure statistical chance and there's plenty of sources that will tell you that

Given the almost uncomprehendable size of the universe, yes. Odds are that there is life out there. But these odds are as usaful as the idea that the number pi, because it's an irrational number, contains every answer to every question ever asked as well as all things known and unknown. Conceptually its very interesting but in reality it doesnt mean a damn thing.

@needmorec4 I don't think you know what those words mean...

I say that if there are "aliens" they're exactly like us. We have never seen life form differently on other planets. For example bacteria on mars is the same as on earth. Why would the life forms suddenly change?

Because... evolution makes species life adapt... of course they would be different because they would've evopted fir a different environment

"We have never seen life form differently on other planets" - on how many planets have we looked? We cannot even tell for sure wether all laws of physics are valid everywhere "out there" and the diversity of life forms on this very planet is, well, diverse ;-) so the assumption that aliens "are like us" is actually based on watching Star Trek and not science.
