What is genre of chapters 1-11 of Genesis?

Probably ancient stories, (could have been borrowed from Mesopotamia, but not really likely) used to bring out things that happened, e.g., God made all things, in some special way made first pair, gave some sort of command, they violated it, fell from favorer grace. Church never taught fundamentalism. Even Augustine said, about the clay image, that God does not have hands. St. John Chrysostom said the Eve incident should not be taken crudely.
