@selzero meanwhile a Jewish claim on the land is biblically justified, to whatever extent one might believe that the Bible is literal truth.
Being thrown into a diaspora because of centuries of others determined to kill you and your people, and reclaiming land that was promised by God is a justification as powerful as you saying well, they were living there and that makes them indigenous, so by what right do you displace them?
In that context, your argument cannot stand, either.
