The ancient people who penned Genesis and the Pentateuch (Moses), and the old and new testaments, did not care about the modern sciences, what they cared about was knowing the true and living God. Moses was a theologian, not a scientist.
The Bible is about knowing God himself, about spiritual things, and faith. God himself is what commanded Moses thoughts. God is always at the center of all events in Genesis.To try to interject modern scientific thought into Moses, and the ancient and primitive people to whom he wrote, is ludicrous.
