Since all the available scientific and archaeological evidence seems to point in the direction of all these being human ideas, how do people convince themselves that there is a God to make laws in the first place?!
I suggest that the word god has different meanings for different people. But the basic meaning, I think, is the meaning that people find in their lives. It is what works for them. The idea is very much a part the ‘equiptment’ that evolution provides us for survival. Like lions have big teeth and claws, and cheetah have great speed, we have ideas, god being just one.
