I'd have to look at the archaeology, tge records from other civilisations and the internal eidence fromnthe text to have an opinion. I haven't in any detail.
There's no evidence that anything in Genesis happened. In fact, what we know of the history of the Earth flatly contradicts the creation story and the flood story. There's no evidence of the patriarchs or Joseph.
Exodus is a bust. There's no evidence of a large Hebrew population in Egypt, Moses, the flight from Egypt or the wandering in the desert for forty years.
There's no evidence that Joshua conquered Canaan. In fact the archaeology suggests the Hebrews were indigenous inhabitants of the region.
The alleged Davidic empire is mentioned nowhere except in the Bible. The only reference to it is a tablet that says somebody wiped out the Houser of David. Solomon is equally illusory.
It's only when we get to the two kingdom period that we have solid history.
