The Torah is important to Judaism primarily because it tells the story of the origins of the Jewish people, including their beliefs, laws, and covenant with God. It is considered the foundational text of Judaism, containing not only historical narratives but also laws, ethical guidelines, and teachings that shape Jewish identity and practice.
While the Torah does encompass themes related to monotheism (the belief in one God) and includes prophecies, its core significance lies in its role as the central religious document that outlines the covenant between God and the Jewish people, their responsibilities, and the principles of their faith.
Thus, the most accurate answer from your options would be:
It tells the story of the origin of Judaism.
