There's one thing I always thought about religions: they're here just to comfort people's feelings of uselessness, emptiness and obviously lack of meaning. I've seen that some of the more intelligent people around end up believing in higher beings, because standing in front of an endless void would surely eat away all your sanity. This is what happened with some philosophers.

On the other hand you have people that refuses to believe, interpreting it as a "weakness" of the mind. They prefer to focus on earthly experiences instead of looking for undetermined, non-defined deities and supreme powers. There's a clear example, Nietzsche, who lost his sanity by the end of his life. That's something to learn about maybe.

I'm at a middle stage here. I don't believe that there's such a thing as God, but I'm deeply concerned about this topic and always opened to think deeper, and obviously accepting the human existence as a biological causality leads to torture yourself a great deal if you're the kind of person that tends to ask questions without any satisfactory answer. But I guess that, even so, I'd never believe in God, because scientific truth is the only we can know about.
Our senses are deceitful and they only show reality from a human perspective. We know nothing, and we'll never do. Starting from this point, you can fill your beliefs with whatever you want, but you'll never be 100% sure unless you've got faith, and I seem to lack a bit of it (because it proves nothing).
I prefer to find meaning in Arts, from literature to metal music. Sometimes it's enough. Sometimes don't.
