Aliens?

[LadySam]

Hmm i guess there may be other life forms, be it aliens or anything else. But i don't think they are any smarter than we are. Otherwise they would have found us and taken over our planet. I have a professor who is 1000% positive there is aliens and UFO's out there, but im not fully convinced. Even when i watch documentaries on aliens i don't really believe them, i mean if they know for sure, then why not spend all their energy on actually finding them and proving it instead of telling us all about their 'theories'.
