So, do you think Palestine was just an empty land until Europeans sent Jews there?

Why do you think Jews were sent to Palestine? Because Europeans were racist. Jews were persecuted in Europe for centuries: scapgoated for the black death plague, Inquisition by Spanish, Progrom by Russians, and Holocaust by Germans. Europe even needs anti-semit law to protect Jews from racism.

Relocating millions of Jews from Europe to Palestine was a bold racist act by Europeans. And you didn't even touch this issue.
