technically yes..but has anybody seen that movie where this thing has to go really fast and it ends up going into the bottom of some testing facility lake and the thing goes through a black hole and the container the person is in gets translucent and the girl ends up seeing aliens and talking to them and the alien is in the form of her father and the alien says its like that so its easier for her to comprehend whats going on....
I've had a few encounters with them. Our universe is so huge and it's expanding more. So, you never know if there's going to be life in it, but since I had a few encounters with them, I do believe in them so much. Also, Area 51 has UFO ships and Alien creatures.
I believe they are. Imagine the infinitive spread of the universe. Seems illogical that we're the only living beings in the universe. But then again our circumstances are so unique that Earth has produced the correct components for life. If there are aliens, they might be similar to us, or be less complex organisms such as bacteria. We'll never know for sure, but in the future we could know for sure.
Research the Nephalem. Something else to think about: the hebrew definition of heaven. Look it up. The first, third, and second heaven are dimensions or alternate universes not "places" like a map. Those are just the dimensions we know about. I'm sure there are others.
