“Other people’s land” Jews never left Israel. The Jewish community in Palestine - which was one a majority - shrunk to tiny numbers, but they were always there. And the Jews who were deported/forced to leave and ended up in other parts of the world never stopped trying to go back.
Jews are from the Levant - that’s an indisputable fact, Jews are not native to Europe - the bible is irrelevant in establishing that fact. Genetics and archaeology do more than a good enough job. You just exposed that you know nothing about the history of the region.
