I doubt it was ever the intent of it’s authors to provide a literal description of creation, any more than it was the intent of the author of the tortoise and the hare, to describe an actual race between a mammal and a reptile. Even children can grasp the principle of allegory
The impulse to characterise our Bronze Age ancestors as ignorant simpletons, is wholly erroneous in my opinion.
Really? I would be curious as to what informs that analysis. What is the date at which the Genesis creation account first appeared? Is the account derived from, or a modification of a previously existing story? If so, when was that first composed?
Once you set the date, what other material do we have from that time period? Is there explicit documentation from that time period that suggests listeners/readers considers Genesis creation account to be taken non-literally as in allegory or parable? If they considered it non-literal, what were their thoughts on how the world actually came to be?
Is there a tradition at that time of non-literal fiction in the form of allegory, fable, metaphor, or other figurative forms? Be careful here as I am talking about the time period when the creation account first appeared, not in the Bible compilation we have today. What would be some examples?
What about other cultures? What is the documented attitude towards creation accounts, at the time the accounts first appeared, in other cultures around the time you date Genesis creation account, or earlier? If they considered these stories non-literal, merely allegory or parable, what did they consider the reality to be?
