This is complete opinion here, as there is nothing in the Bible (as I have read) that talks about life on other planets. But given the view that the universe as we know it was created for humanity, the stars in the sky and everything, to provide light for the world, (again Genesis, everything hangs on Genesis being true in Christianity, with out it the purpose of Jesus Christ becomes null and void), I think that there is not. All things were created to sustain life here on Earth. This too is something I would like to talk to my pastor about, so many things. I feel like I could spend a couple of months talking and learning more about these questions.
But... I do believe in Angels and Demons and that they are present all around us....
That is clearly documented in the Bible.
