If God does exist, and wanted to communicate his role in creation to Semitic tribesmen five to six thousand years ago, he'd probably simplify his message to get his point across. He'd lose his audience pretty quickly if he tried telling them about these tiny building blocks that you can't see but which come together in long strands to form a blueprint for every feature of every living thing on Earth, etc. Instead, the point is clear: I made you. You owe me some respect. For me, the Old Testament is comprehensible as a mix of anthropology and a sort of Divine poetry. The original Noah story was of a Mesopotamian farmer who was told by his god(s) to put all of his wealth (his livestock) and family on a barge, just in time for the flooding of the Tigris or Euphrates. A game of telephone turned one man's animals to all animals on Earth, a river landing to the re-population of the Earth. The point is that God wants us to listen.
