HUMMM, lends credence to the theory that the Philistines had Greek origins. didn’t the Egyptians call them the SEA People?
The Greeks may have invented the word "Philistine," (I really think Herodotus used the word "Palestine.") but that was how they identified a distinct group of non-Greeks.
As for the "People of the Sea," there is at least some doubt as to who they were. Velikovsky thinks they were Persians. (Also see: here.)
