It's naive to believe something because a man in a white coat told you. But it's also naive to believe a book word for word that could have been written by anyone. Personally, i think there must be some form of higher power either in the universe or just sat watching it, maybe because fear's taken over and i dont want to die and nothing happen after, or because i think theres still so much unexplained - how did the universe get here? What's past the universe? If the universe is ever-expanding, what is it expanding into?
Science vs religion - your choice.
