Probably every single person in the region is a descendant of the Jewish people who "lived in that region first".

And if we go back further: If Abraham existed, then like 99.9% of all living humans are descendants of Abraham. Do they all have claim to Israel's land then?

It doesn't make sense to look back that far.

Also a very large percentage of the current Jewish people in the region are descendants of European colonizers. The original Jews converted to Islam over thousands of years, then Jews from Europe came over just after WW2 (this was the Allied counter-proposal to the Holocaust) and said it's ours now.
