I have concentrated my study and have taught the Book of Genesis for the last eight years. There is no indication at all that chapter one is poetry. Hebrew experts have affirmed over and over again that it is historical narrative.
I am wondering how you can narrow down "the point" of the chapter to show "the inherent goodness of creation?"
There is now growing scholarship to indicate that Adam wrote Genesis 2:4 to 5:1 on a clay tablet. That tablet, and 10 others, were probably used by Moses to compose the first 37 chapters of Genesis. Trace the use of the Hebrew word, "toledoth."
Moses had access to Egyptian resources and sources. No doubt he could read and write, and if during the times of the Hyskos, he would have been reading and writing in proto-Syriac script (which is, itself, derived from Phoenician, which is derived from Egyptian hieroglyphs). He would have had access to materials written in Sumerian as well (as would have Father Abraham ~ he traveled throughout Sumer).
Writing was well established by Moses' time. Moses said himself that he wrote the Pentatuch.
