"Very close examination of the "genes" Israeli Jews, Israeli Arabs, and Palestinian Arabs hold in common as "markers" strongly suggest they are all the very same people, and different from those around them."
That's not true. Genetic studies confirm that populations from the Middle East, including Jewish people, are
related, just as one would expect to find in any geographical region, but not
identical or "all the very same people".

The Biblical account of the history of the Jewish people in the Middle East has extremely strong support in the genetic code. Abraham came from
Ur of the Chaldeas, which is modern Kurdish country, and the Jewish people are more
closely related to the Kurds than to the Arabs.
However, all Middle Eastern populations share a common genetic ancestor if you go back far enough, just as all human beings share a common genetic ancestor.
Not sure you are disputing what I said. The critical genetic markers at issue show that both the Jews (in general, but not in every case of every individual) and today's modern Palestinian populations are very closely related to the Kurds (the ancient Medes), and not closely related to the Arabs.
I think this explains part of the "problem" of trying to live in the Levant over the last 4,000 or so years.
Many other Levantine groups only loosely identified as Caananites in more ancient times, share in the exact same origins.
