I'm acturally still trying to figure out what a Jew acturally is because some people say they are Jews but they converted to the religion of Judism. I thought Jews were the biological decendants of Benjamin and Judea branched off from the other 10 tribes of Israel. I don't know.
I met a dude once and he said he was from Israel and I asked if he was Jewish and said no he's a Israeli, so I got confused. He looked Jewish, was from Israel, and said hes not Jewish he's Israeli. And I said ok.
What's the difference?. Maybe he wasn't religious?. I don't know, I just left it there and didnt question anymore.
