The Jews are not black. That's ridiculous. You have no idea what you're talking about. The Tribes of Israel were from eastern Mediterranean not Africa. There's no evidence they came out of Egypt. There's no evidence they were ever slaves. The Roman Catholics were not around until the 11th century AD. What are you talking about? The bible is a fictional history that didn't happen. It was based on traditions recorded by dozens of authors over the course of several thousand years. Even individual books were written and rewritten, edited and reedited to evolve with the cult.
Jewish is English. In German it's Juden. In Latin it's Iudean. In Greek it's Ioudaios. In Hebrew it's Yhudi. It means "The People of the land of Yhuda." Yhuda was the son of Yisra'el/ Ya'akov.
Honestly go to college or something. Learn to read. When you become certified in near eastern mythology and archaeology maybe you can surpass my amateur interest.
