I'm just curious as to what kind of evidence you'd expect to see.
It is not about what evidence exist for Israelites in Egypt.
If they were there, there would be trails leaving Egypt and camps set up that would still exist today in an arid desert where we can see Camps from that period from Nomadic tribes.
We would also see the highlands of Israel being populated from a mass migration as the people arrived.
The problem is, it is all mythology, all of the early history is factual pseudo history.
Monotheism did not start with Abraham, there was no Moses, No exodus, No Noah, no flood, and no Adam and Eve. And no credible historian debates this at all. All that can be debated is what historical core has a possibility of starting this mythology.
NOW lets get on to facts. It is a fact there was no mass migration, we see a gradual increase in houses in Israelites highlands after 1200 BC all the way to 1000BC At this time these people are factually known as proto Israelites because they still resemble the displaced Cananites they evolved from.
These people known as proto Israelites factually used Canaanite mythology and deities, the Canaanite alphabet, and Canaanite pottery.
The picture is so clear there is no debate.
Monotheism did not start as the bible states it did either, it factually started after king Josiahs reforms after 622 BC
Much of their mythology was influence by Mesopotamians while they were there in exile. The Babylonian's oppressors wanted these multi cultural oppressed people to have one religion and at this time multiple traditions were compiled together. that's why we get two creations stories and two different flood stories.
We also had tow deities fused together at this time. The "father" El and the warrior Yahweh.
