What do you mean. My ancestors lived here for centuries, millenia even. I'm the actual descendant of the same people who you claim, falsely, to be the original sole owners without proof except a book only you and the person sent you my way believe in. You falsify evidence of having a genetic connection to my ancestors, and claim, falsely, them to be yours only.
For millenia, I owned the land, empires came and empires went, I owned the land. Most remaining jews after exodus from Palestine converted to Christianity, and later most of those converted to Islam.
Palestine has always been a melting pot for multiple cultures, multiple nations, multiple tribes, and multiple societies. It was never owned by Jews and Jews only. Even during the heyday of their ancient kingdoms, they shared the land with others. Current day Palestinians are the descendants of all these cultures, nations, tribes, and societies.
Having said that, you're welcome to live on the land as a guest, but you're absolutely not welcome to dominate it.
