What would that do to alot of people's religious beliefs.I mean if people colonize mars.end time's. hell on earth and all that crap.
Religion will have it's downfall. It's a rotten foundation and it's structure will eventually come crumbling down. I don't think that will ultimately serve humanity any good though as religion serves it purpose to control and conform a civilized society, like laws of any nature.
Without those, society suffers and can only become worse in my opinion. So in actuality I would like to see religion strengthen and prosper as I think it gives a lot of idle minds, potentially dangerous ones, a place to find solace.
UFO's have been documented as long as man, so yes, there are most definitely other creatures that visit us, it's all speculation from there. I have my beliefs on it and they're kind of out there, lol.
