I think God is something that people use to avoid reality. I think faith allows people to reject what is right in front of our eyes, which is that thing, this life, this existence, this consciousness, or whatever word you want to use for it, is all we have, and all we'll ever have. I think people have faith because they want and need to believe in something, whatever that something is, because life can be hard and depressing and brutal if you don't.
