The Arabs came and left just like the Ottomans came and left. The Arabs left behind their religion, language, cuisines, Arab customs and traditions, but not their DNA – meaning that the Arabs from Arabia did not mix their blood with the indigenous populations. Today, there is a unique DNA call Arabian-Peninsula but you don’t see it when the Iraqis, Jordanians, Lebanese do their DNA tests. You have to have some evidence when you make such exaggerated claims that the people of Palestine came from Arabia. Then you would have to tell us where are the people that the Arabs found there when they first arrived?
