Douglas Hayworth has a guest post over at Steve Martin's site, An Evangelical Dialogue on Evolution. It is on teaching evolution in Sunday School. He writes:
The creation, garden, and flood narratives are certainly MORE THAN mere stories, but they are NOT less than that. Just as the four gospels cannot be understood properly (or the differences between them reconciled) unless each author's individual theological purpose (i.e., "story-telling purpose") is appreciated as the primary framework, so, too, the creation narratives cannot be understood without keeping in mind the story-telling context.
This is the same point that Conrad Hyers makes in his book The Meaning of Creation.
