I think that given the evidence I have seen, the best explanation is that we live in a natural universe with no God, but as I have not seen any definitive proof, I can not say for sure there is not one. Only that if any human being is exactly right about the nature of God, it's strictly a coincidence.
By your standards that would make me an agnostic, but I would consider myself an atheist. An agnostic is somebody who weighs the possibility of no God and the possibility of a specific interpretation of God relatively equal.
My observation about religious people is that their religion validates them doing what they wanted to do anyway. If people want to help people and do good, religion validates their desire to do good. If people want to hurt people and make themselves better than others, religion validates that too. You can hardly blame the religion. Religion is a mirror to your shadow self.
