In fact there is evidence of this and its been posted on this website many times.I suppose you have the DNA documents to prove this. The Palestinians don't even claim to be descended from the ancient Hebrews. Some of them claim to be descended from the ancient Canaanites and Philistines (which is a laugh anyway).
NOPE just conjecture and unsubstantiated self interest has been posted. All the rebuttals have been ignored because they show the ONE geneticist who expounds this theory is use false data.
