God can be known through the light of human reason by studying what he created. So you are <ahem> agnostic because it suits you. And have never known the benefits of fellowship with God.We can't know there is no god. That's the opposite of you have never seen god and can't prove god exists. Neither have been proven. So we remain agnostic. Why would we say "there is no god"? We remain open.
But from what we see, there is no god. And the way we are atheist is about your religion that says god met our ancestors. Are you stupid? Or do you think we are? I know most humans believe that shit but come on man. You really believe in God? You're a god? I mean you say you're going to heaven to live for all eternity and never be sad or sick. You're a god. And we're supposed to buy that? Without any proof? So on that, I'm pretty atheist. In other words, I'm pretty sure the Jesus story is a myth. I'm confident enough to lean towards atheist.
Because remember The existence and non-existence of a god are not equally probable outcomes. Thus, belief is not as valid a position as skepticism when dealing with unsupported or unfalsifiable claims. Agnostic atheism is the most rational position.
As for your belief that the existence and non-existence of God are not equally probable outcomes that's true but the opposite of what you believe. There's plenty of evidence for the existence of God. Just none you will accept.
