How has judaism evolved into a culture?

That was a religion that the Jewish people had followed and believed.

Judaism evolved into a culture because of its followers that are born into faith. This happened in the beginning during the time of Moses in Mt. Sinai where he was with newly freed Hebrews. This was the time when the 613 statutes were tailored for tribes who were trekking in search for nationhood. They were ancient people who were lost and needed a sense of understanding about how the world should work. Eventually, their beliefs were rooted to an existence where love, fairness, and goodness rules during their lifetime.
