Examining literary forms isn't a total waste of time, but, if we're writing about a document's function in its original society, form adds little to our understanding. The Genesis creation story is the antithesis of those of surrounding cultures. It is clearly meant to set Yahwism in contrast to the beliefs of "outsiders."
I can visualize an elder sitting near the fire retelling this story to teach that Yahweh is the one true god.
Perhaps your time would be better spent examining the uses of this narrative within Hebrew society as shown by parallels found within scripture and by examining contrasts with neighboring religious. Just a suggestion.
Exposing another's lack of depth may not be the best way to educate them. Doing so tends to become insulting rather than educative. PSch's reply covers his/her own lack with insult and impatience.
