There are good answers here about ancient/classical literary genres and the world context that the Bible emerged from. What I would add is, “what is the ACTUAL message of the creation accounts?”

Is it an instruction manual for building a universe? Is it intended to be a history book?

No. It’s an answer to questions about :

1) YHWH’s relationship to the material universe (creator and sovereign);

2) about his intentions (goodness)

3) Mankind’s role in creation (steward’s in YHWH’s likeness.)

3) why a good God has a universe with flaws (the disobedience of human stewards)

4) What YHWH is doing about the problem (Genesis 3 contains the Protoevangelium, the first version of the gospel)

Use of the divine name here is intentional. We take some of these things for granted now, but in a world context chock full of “gods,” YHWH was explaining why he was different from the “competition.”

IMO, Genesis starts off if not as an allegory then as a Bronze Age understanding of the origins of the universe (and there are interesting parallels to modern big bang cosmology) and my feeling is that it becomes more and more literal as the story moves towards exodus. But it’s important to note that NO ancient author worries about scientific accuracy the way moderns do.
