I believe in a God. However, I don't believe in Jesus or the bible. I don't think you should base your religion off a book or worship whoever and however because of what a book says. I don't believe in what the bible says anyways.
Look, I've passed your phase. I almost don't believe in God too, but God does exist. "why is there evil in the world?" bcs God wants to know whether we will fight it for our own good or let it be what it is. And also bcs the world is going to end someday, thats probably why he creates evil. If God already gave us everything in the world, what's a school for? What's a parents for? We're not perfect but we keep trying to be. We need to learn, God wants us to learn.
I'm an atheist, so I don't believe in God. But what most people believe is that God gave us free will, and he wished for us to be good. But gave us the choice to be evil as well. Some of us choose good and some of us choose bad.
But like I said, I'm an atheist. So I don't believe in God at all. But I know a fair deal on religions.
