What are similarities between

Zoroastrianism, Judaism, and the Vedic religion?

I will foremostly emphasize one particular similarity. Hinduism, Zoroastrianism and Judaism are all systems which contains much more than just a set of religious beliefs and rituals. They moreover collected the folk reminiscences and traditional narratives of their respective ethnicities, systematizing them into a complex sets of sacred history and national myths which turned to be an extremely persistent source of the ethnonational identity.
