No, but we have established that many Palestinians have been there long before the Arabs.
Can you provide an archaeological record verifying a civilization called "Palestinian" existed before Arabs?
No, I didn't think so.
Because, Palestine and Palestiniains are a recent invention.
Historian Bernard Lewis...
The adjective Palestinian is comparatively new. This, I need hardly remind you, is a region of ancient civilization and of deep-rooted and often complex identitites. But, Palestine was not one of them. People might identify themselves for various purposes, by religion, by descent, or by allegiance to a particular state or ruler, or, sometimes, locality. But, when they did it locally it was generally either the city and the immediate district or the larger province, so they would have been Jerusalemites or Jaffaites or Syrians, identifying province of Syria
The constitution or the formation of a political entity called Palestine which eventually gave rise to a nationality called Palestinian were lasting innovations of the British Mandate
