Well it is obviously a metaphor, for what is up to debate. Though you touch on some pretty common metaphors people find in the bible. I think most of that first paragraph is all generally accepted stuff, though some of the later stuff is a bit of a stretch. Like the rib being about dna, that is pretty out there and doesn't seem at all likely. Then again I don't believe any of that stuff happened at all. I think it is an entirely made up story, though people during that time were entirely capable of writing stories with metaphors and those people were asking a lot of philosophical questions.

That is how faith came up, from early people trying to figure out their place in the world. It isn't surprising that a person today, asking those same questions, might find similar thoughts from people of that time period.
