Who is a Jew?

A Jew is someone who follows Judaism, which is a religion that started a really long time ago in a place called Israel. Judaism is based on a holy book called the Torah, which talks about the history and teachings of Jewish people. Someone can become a Jew in a few different ways, like being born to parents who are Jewish, studying and converting to the religion, or being accepted by the Jewish community. Being Jewish is not just about a religion, but it is also a cultural identity and a way of life for many people who share similar traditions and customs.
