Judaism came first. The true, orthodox religion (Torah), not the hijacked (by Europeans) secular one (Talmud), is based on the Law of Moses. Moses came before Jesus, which makes Christianity younger than Judaism.
Christianity was hijacked and taken over by European racists. They even destroyed the true image of Jesus (who was BLACK) and re-wrote or deliberately mistranslated large sections of the Bible to give the false belief that (1) Whites were the original people of Earth, (2) Everyone spoken of in the Bible (except otherwise noted) are white, (3) Whites are the chosen people of God, (4) Whites are pure and God-like, and even (5) God is white (via implication).
