If anyone should have a moral right to the territory of Palestine (or as some call it, "Israel" -- but that's not what it was known as for those two thousand years, nor even before that!), it should obviously, by your own logic, be the (descendants of the) Ur-Canaanites!
The evil Canaanaite-butchering Jews should, in view of that little piece of history, not be allowed to profit territorially from their (attempted?) genocide -- perhaps the first instance of such, at least the first historically recorded one ("The Mother of All Genocides", I'm sure they'd call it, if some other Middle-Eastern Semite bloke hadn't come up with that idiom first...).
Their having "prayed" thrice a day for a couple millennia is of course neither here nor there -- except, if anything, as even more cause *not* to let them have it: It is nothing but a celebration of their victory (=genocide of the Ur-Canaanites), a horrendous crowing over the blood of the dispossessed that can only serve to further DIS-qualify them from ever being allowed to enjoy the fruits of their vicious blood-lust.
There, that's what you get if you want to base the strength of your claim on how *old* it is. Sheesh... Are you really *so* stupid that that wasn't obvious, even long before you tried it?!?
No wonder, then, that your argumentation is so reminiscent in *style* of that of the Serbs in regards to Croatia, Bosnia, and Kosovo: It's just as *brain-dead*, too!
