Did early hebrews develop judaism

Answer 1

Yes. Modern Judaism, rabbinic Judaism, grew from the Judaism of the rabbis in the great academies of first millennium Babylon and Palestine (where the Talmud was written). These academies were founded by students of the Pharisees after Rome destroyed the Temple in Jerusalem, and with it the sacrificial cult of the Temple. The Temple, in turn, was rebuilt after the end of the Babylonian Captivity by Jews returning from Babylon. The Temple in Jerusalem was originally founded as a home for the sacrificial rituals described in the Torah, which was the Holy book of the Hebrews at the time they occupied Jerusalem. Note, of course, that this is the evolution of a religion. I strongly suspect that the Pharisees of 2000 years ago would be as surprised by modern Judaism (in any of its forms) as Paul the Apostle would be surprised by modern Christianity (in any of its forms).
