You're being disingenuous; if we call them not just Palestinians, but Philistines or the Peleset, then they are mentioned in multiple histories of the region. While the region passed through Roman, Turkish, and British control, the only time when there was a large influx of foreign folks was during the Islamic expansion, when many Arabs moved into Palestine. Other than that, they've been there since around the Bronze Age Collapse; their history traces through the Iron Age just like Israelite/Jewish history.
