I allow that the bible states many important ways of people living together well. But the "living together well" came first and the bible simply codified that. Humans have been homo sapiens for about 200,000 years and learned how to live together all that time before the bible. That some ancient nomadic tribe consolidated a few vague legends (a flood, a few battles, a time of slavery) means very little in the course of human history (as brief as THAT is).
There is nothing in the bible that is not taken from other older cultures, and little advice that wasn't already understood in the cultures that surrounded them. Seriously, do you think think it was a revelation that one should respect the elders and not steal from neighbors?
The bible is only the first written record of standard inter-human practices by a small tribe of nomads who met a lot of other peoples and caught on to writing at the right time.
I do admire them for that, BTW.
