I'm not sure why you put "history" into quotation. I was referring to history as in archeology.

The arguments are according to pottery and art in general, linguistics and I think genetics too. The first israelite settlements were in the north and therefore not were you would expect them if they arrived from Egypt. I don't know if Abraham was a historic figure and it honestly doesn't really matter.

Yeah, iirc the Isrealite ethnic group was a combination of Canaanites and tribes from near Canaan that invaded during the Bronze Age Collapse. Though the religion is mostly Canaanite-derived, Yahweh and Elohim, the two main titles/names used to describe the Abrahamic God in the Torah are descended from the Canaanite gods Yaweh and El, who were syncretized together into a single god sometime before/during the early 1st temple period.

Edit: Though there's also loads of Mesopatamian influence, the Noah's flood myth is directly based on the Mesopatamian flood myth that eventually made it into the Epic of Gilgamesh. Plus lots of ancient Isrealite folklore is derived from Mesopatamia, like Lilith, who is probably derived from a kind of demon in Mesopatamian mythology that fed on newborn children and was in league with Lamashtu, who was basically an Anti-Fertility goddess, considered responsible for infant mortality.
