Plus even if god does exist and is all powerful (unlikely) it is still accepted that man wrote the bible and it is littered with personal bias and outdated opinion, and cannot be treated in its entirety as the word of god. And when you enter the realm of asking what is wrong and what is right within the bible, you get to the question of whether any of it should be believed at all.

The existence of god will never be proven or disproven, and atheists make the mistake of starting from that point when the real question is whether the religious doctrines have any merit, and whether people should follow them. I do not reject god completely, but what I do reject completely are the existence of the Christian god, as well as the existence of Satan, heaven, and hell.
