Yeah, i believe in Aliens. I believe in other dimensions, in evolution. Also, i believe there is greater technology on Earth, than we know little about it. When i say aliens, i don't think about green people, but some inter-dimensional species of some sort :/. The universe is very big ! Imagine all those planets like Earth, filled with life , all those civilizations ! In my opinion, right now, Earth is a "crap carrier". I think we need about 600 more years to live in peace and conquer space .
