[Do you know any Ur-Canaanites?] I don't.Oh, I think I possibly do -- in which case, *you* know even more.
You see, I don't think your semi-neolithic ancestors were 100% efficient in their genocide (Hey, I freely admit even mine weren't, and they were industrialised and everything!)... So some of the folks who were there before them, probably hung around after their arrival too. Or do you have some other explanation of where all those Samaritans, and other such peoples your holy books are full of, came from?
And then, later on, after the Romans came, then began the Diaspora. The Jews left, History tells us... Does it say anything about what the *non*-Jews in the area did? The Romans didn't pull a Carthage on the whole country, did they -- "kill every living thing, sow the Earth with salt", that routine? So they probably just staid put, I'd guess... And that's your Ur-Canaanites right there: The Palestinians.
Those nations ceased to exist at some point and therefore thereis no one to claim the land.Oh, those NATIONS "ceased to exist"...? You mean, like the NATION of Israel did, two thousand years ago?
The jews on the other hand have not, and have had a continous presence in Israel for thousands of years.Not as a nation they haven't; no more than the Ur-Canaanites. Just a scattered splinter of a people, getting assimilated into / assimilating into itself the surrounding culture, like any other such scattered splinter of a people has always done.
Funny how in your book, *that* counts as "continous presence" (for a *"nation"*, no less...) -- while pretty much the exact same thing happening to the people who have their dicks uncut counter-clockwise in stead of clockwise, or whateverthefuck, counts as "ceased to exist".
Now, if you want to be adamant that the Palestinians aren't the descendants of the Ur-Canaanites... AND at the same time, you want to claim that "a nation" of Jews lived on in Palestine after the Diaspora... Then what do you think would have happened to that "nation" about half a millennium later, with the rise of Islam? Well, what happened to EVERY fucking *other* people that wave rolled over? (And spare us the "JHVH fixed it somehow" craplications, OK? We're talking history here, not superstition-based fables.) Yup, that's right... They converted.
So if the Palestinians aren't descended from the Ur-Canaanites, and thus vicitims of attempted genocide by the Israelites for the SECOND time... Then they must be descended from the *Israelites themselves*, for all I can see -- and thus the vicitims of attempted FRATRI-genocide by the Israelites' *other* descendants!
That's your precious "nation" for you: The Mothers Of All Genocidists -- either repeat killers, or brother-slayers.
