It is also my long-standing belief that the “sea people” who ravaged the middle east and basically ended the bronze age, were the Jews and or the people the Jews drove from their historic lands when they invaded the promised land.
I think people are thinking of sea people in the wrong way. They are thinking people who attacked by sea, when instead it is the people that crossed the red sea when Moses split it.
It is also my opinion that the lost tribes of Israel are simply those tribes who choose to interbreed with other pagan slaves freed at the same time as the other Jews. These tribes who were already an ethnic mix then intermarried with the remains of the pre-existing peoples in the parts of the promised land they occupied until eventually they were basically “lost”
Sea peoples were the Phoenicians and Levant tribes that proceeded them like the pre-bronze Ghassulian were probably seafaring also. But yes they were originally from around the Levant.
