Even if what you say is true, then you must admit that the Bible is not worthy of belief.
That's an odd conclusion.
You seem to be trapped in a prison of two ideas. On or off. White or black. Hot or cold. Up or down.
The truth of the world is that almost nothing is either this one thing or this other thing. Almost everything is a valuation of many and varied degrees.
My view of religion is the result of this sort of consideration.
My feeling is that there is a supreme Being and that this supreme Being tries to communicate with Individuals.
Individuals, then, try to relay what they have experienced and the messages are colored and changed based on the cultural and geographic influences the folks are saddled with.
We see this sort of thing all the time. One person says something and 10 people take away 10 different understandings of what was said.
It seems reasonable to think that people say to themselves, "He couldn't have meant what he seems to have said. He MUST have meant to say this other thing".
People do this with EVERYTHING. Why not with the word of God or with the word of many gods?
If a Divine Master of the Universe contacts Moses, Moses might think he's talking to a singular, Pharaoh style entity. He was raised in that sort of a culture.
American Indians might understand the message(s) as plural manifestations connected with particular critically important elements of their survival system as hunter gatherers.
Greeks might understand that message as congregation of contributing and competing entities vying for superiority.
Appreciating the values of a thing does not necessarily demand that we embrace those things that don't seem to hold value.
The Bible, TO ME, can have and hold a whole bunch of value even if it was written by folks who were not in command of all of the wisdom of all time for all things.
Does that make any sense?
