there is simply no destruction horizon in the region that fits the story line, remotely. we can trace the introduction of the philistines (do those phonetics look familiar? they should.) from greece, but the archaeological record presents absolutely no evidence at all of any sort of movement from egypt to the levant at any point close to the accepted chronology in the iron age. archaeologists talk of the region being a sparsely populated backwater, and of a canaanite-phoencian complex that shows remarkable continuity going back to the upper neolithic.
it's worse than that, though - because the west semitic people that lived in the region for thousands of years before the assyrians, and were descended wholly from canaanites, really were expelled or otherwise slaughtered by the assyrian invasion and occupation of canaan, or south phoenecia (the phoencians did in fact call themselves canaanites; phoenecian is a greek label). hebrew ethnogenesis, as we understand it, really only starts when the persians allowed some other group of people to move into the land, after the assyrians had cleared it out.
not only was the whole thing probably made up in assyrian-occupied babylon, but there's no evidence that there were any jews before the captivity at all.
that's science, and that's what socialists and the left are supposed to uphold as having primacy, not superstition and legend and ignorance. most jews nowadays are actually strictly secular and atheist and seem to grasp that, which makes them a little different than adherents to the other religions.
