I believe there are many intelligent aliens much like us, perhaps billions of planets with them scattered in different galaxies in the universe. We really don't know if our universe ever ends, so any answer could be right IMO.
I just really doubt we'll ever be able to meet any of these intelligent human like aliens because they're just so far away. I'd think it take too many years for us to be able to go so far and by then the world would be over....and the cycle of life would just start over until that small .000001% or w/e percent happened that two alien people like us met.
I think if we do by happen see aliens much like us, it'll be a extremely rare occurance or proof in the future human-like beings will be able to evolve and go off earth like planets to adapt to space, different planets, or space station?
Or maybe there are extremely advanced aliens that just don't care to talk to the likes of our basic forms. Perhaps they move at such a faster rate and live such a longer life that they don't notice us or are just too fast for us?
As far as afterlife goes, as a Christian, I definatley believe in that. I believe the good shall live with the good, and the bad with the bad.
