TS,
On Genesis, I see the toledots (generations of) defining the internal structure. This starts with Gen 2:4, so the question is what is before that? It is some kind of intro section.

One needs to realize that Hebrew poetry does not necessarilry conform to our ideas of poetry. Hebrew poetry is OFTEN characterized by repetition and parallelism, either of words themselves or of rephrased ideas. This is one reason I see Gen 1 as poetic narrative.
