There has been a continuous Jewish presence in the Holy Land/Roman Palestine, Turkish Ottoman Empire Palestine, and British Mandate Palestine for over 3,000 years. That is the claim to the land.
There never was a Palestinian people or nation in history. There are no history books from before Yassir Arafat and Nasser created a “Palestinian people” in the 1950’s, but openly in the 1960’s.
There was no Palestinian nation, government, history, newspaper, international recognition, pottery shards, parchment papers, or anything else to show that a Palestinian people ever existed.
Most “Palestinians” came from Saudi Arabia, Transjordan, maybe Yemen, and Syria. Very few were native born to Israel, even before the 1880’s. Read what Mark Twain and Winston Churchill wrote about that region and who lived/didn’t live there.
Of course this all was settled at San Remo when Arabs received enormous formal lands for Arab nations while Israel only received a sliver. Amazing how when the Arabs won so decisively their quest for land, they still are not satiated unless Israel is slaughtered.
