Don't listen to me, listen to the OG Zionists:

>Ben-Gurion, along with Yitzhak Ben-Zvi (the second President of Israel), argued in a 1918 booklet (written in Yiddish) that the Arab peasants of Palestine were not descendants of the Arab conquests, but rather the "remnant of the ancient Hebrew agriculturalists".

If you'd rather modern science, then there are genetic studies out of Israeli universities leading weight to this hypothesis (they tend to not get much attention among modern zionists as you can imagine). It's also the general consensus among historians of the region, inside and outside Israel. It's not really a contested position amongst academic historians.

>I love how you turned the elimination of hundreds of religions and ethnic groups into some beautiful cultural influence.

It was not always a clean process, varied a lot by century and location, but on the whole did not involve ethnic cleansing or massacres of ethnicities. The percentages of Arabs you quote above are, again, people who started calling themselves Arabs after cultural shifts, and not, as you seem to believe, a result of mass migration of ethnic Arabs from the Arabian peninsula to replace the local populations.

I don't think we have much else to exchange in good faith on this topic, so I'll leave you here.
