I do know what I'm talking about. The Bible is useful as a contemporary report of Bronze Age Canaanite religion, giving a viewpoint (albeit narrow) of their understanding of ethno-theism. It's also fascinating as a record of religious change. Post-Babylonian exile Judaism, led by a priestly caste, redefined a geographically based religion into one that could survive diaspora. People who previously had connected their god to a geographical location that they controlled accepted their disconnect and instead of rejecting their god regenerated their religion from an monolatristic ethno-nationalistic cult into an intensely monotheistic religion. This was sufficiently successfully that there was created a divide between the descendents of the exiled and those who weren't that survived long enough to turn up as racism in the NT (why shouldn't the Samaritan be kind?). This post-exile Judaism, under Hellenistic influence, allowed gnostic cults, of which Christianity was but one, to flourish, especially in the religious freedom accorded by Augustus to the Jews.

The Bible is bullshit. It's no better an interpretation of God than the Argonautica is a guide book to the Black Sea. So, it's the work of man. It could be a guidebook to a supernatural omniscient, omnipresent, omnipotent being; or it could not. The claim is pretty big and the evidence doesn't support it. On the other hand, worship Zeus or he'll fuck your wife. What do you mean you don't believe in Zeus? Why don't you believe in Zeus?
