Let me try again.
God and the idea of God, at least the miracle working creator God, is a man made concept.
God is imaginary. Early man, instead of saying, I don't know all the time for what he did not know, found it easier to say that God did it.
Note how the Bible sells a God that cannot be understood and is unfathomable.
I agree that if god exists then it is not a man with a beard sitting on a cloud but something that I cannot comprehend, so yes the bible would be right (assuming for the sake of argument that there is a god.)
However, the bible also says a lot of stuff that is wrong. If this all-powerful being wanted to send us a message it would choose a much better method than a book that is full of errors.
In summary: I am not saying god does not exist, I am saying YOUR god does not exist.
