You said, "INteresting concept , but i could never allow myself to belive that aliens are demons for one second it crosses to many boundaries .Not only that but if they were demons we'd all be brain washed slaves or we wouldve been wiped out with only the evil ruling our planet".

I don't know what you mean by crossing boundaries, but I have to disagree with saying we'd all be slaves or wiped out if aliens were demons. God is in control so Satan and his armies are limited in what they can do. The problem with them being from other planets is that, for one thing, nobody with the technology to come this far would spend thousands of years just watching us and taking a few samples. And they don't just take whole cows and dissect them, they take the same parts every time, things only devil worshippers would want. There's simply too much about them that doesn't fit the "cosmic explorers" theory.
