I'll let you have the last word because among your difficulties seems to be an inability to grasp the meaning of diluted: “Within no more than two centuries, this genetic footprint introduced during the early Iron Age is no longer detectable and seems to be diluted by a local Levantine-related gene pool.”

If you ever find a reputable historian or geneticist who agrees with your notion that Philistines simply left and no one noticed their departure, please let me know.

As for your general claim about Palestinians, you're wrong again. See https://www.juancole.com/2023/05/palestinians-indigenous-palestinian.html
