I hardly ever question it but I'm beginning to think that there is no deity. I think people are taught that there is one because they're afraid that if there isn't one, there is just darkness in the world.
The absence of a God isn't nothingness and darkness. Morality can be taught just fine without deities or religious dogma. Children can be raised to be good and moral and kind without ever hearing about any particular religion. And it doesn't have to be a dark world, or a world where there's nothing.
Also, it doesn't mean no Afterlife - there can be a place we all go when we die that is much much better than this one - it doesn't have to be connected to a God or to the Bible.
I don't see why people should have to feel guilty or bad about themselves for not believing in deities - and yet that's what happens throughout the whole world. People are being told to believe in one thing and there's no room for any other alternative or any other kind of view.
Just as likely Odin or Xenu exists.
