Noah is a cheap copy of the far older Akkadian Altrahas. The 8 patriarchs correspond to the 8 ancient Sumerian kings. Moses' birth story is a variation of the far older Sargon of Akkad's birth. Moses commandments are a lesser copy of the far older Hammurabi's code. Solomon is a copy of Amenhotep III. After David it might be an actual record, a very loose one with lots of embellishments and some editing of prophecies, Egyptian style. But millions of clay tablets and monument inscriptions very clearly show that Israel was a tiny political entity with little significance to the events of the wider world.
