Bible Question: What was the First Sin?

The expectations I would have for the Bible depend on what you expect me to believe the Bible is.As a written record of traditional Hebrew oral myths? No, I wouldn't expect the Bible to go into every detail, nor provide any more information than is necessary for the reader to get the general gist of the myth.As God's inerrant Word to His creation, detailing every way in which a person should live? I would expect significantly more detail, and at the same time, less outright self-contradiction.Like I said it all depends on what you think the Bible is. It's certainly what we would expect if it's just (heh; "just") a long-surviving record of the myths of an interesting culture. It doesn't even begin to rise to the level of a supernatural dictation from the Creator of All. Don't discredit your intelligence and try to assert that you or anybody couldn't write, on their own, a more insightful and self-consistent bible.
