As for me - I dont give a s**t to aliens, if that's what are you talking about. If they want something of us - why they don't just simply come here and say hello, we are from planet blah-blah, and we say - hey, you had a long journey, come sit by fire...
I mean, if they think that we are dumb and animals or like that, then hell with them. We have plenty of problems here. And I myself don't know, why in movies and books aliens are described as little green peolpe with big eyes. Why you don't expect human-like race? If God created somebody out there, why He should create some little people than another humans, who won't violate His law as Adam and Eve did.
Sorry for lecture.
