well duh, I just saw ants, and dogs, and other bugs and I haven't even left the house yet.
but life with intelligence such as ours? that's a different story

Can you really give ANY evidence whatsoever, in the affirmative OR the negative of there being other intelligent life on other planets?
Saying its stupid to believe one way or the other doesn't make sense. We have no way of knowing right now, and no evidence in either direction.
