The old testament is generally acknowledged as a history book full of justifications for tribal fighting. Read Asimov's book on the Bible for historical context.

Jesus only laid out one basic law: that we love everyone. I'm a universalist, meaning that I don't believe in a god who would send anyone to hell. I think the most horrible among us have no souls and are empty biological beings. So no need to worry about them.

Most atheists are atheists because they see the hypocrisy in organized religion, and the kind of frustration you are expressing. I can't imagine a god rejecting those kinds of people.

Where does this sense of right and wrong come from? Does righteous anger grow of its own accord?

Perhaps it does, but my own personal experiences suggests something much larger is at play.

Francis Collins, one of the human genome scientists, lays out a convincing argument that DNA cannot be a random creation of biology.

His group, BioLogos , is an interesting one, although I don't know a lot about them other than they reject the evangelical resistance to science.

As for Eve? A myth, impossible in the evolutionary timeline.
