From my understanding the Iran_Neolithic people established the civilizations of Elam, BMAC, Indus Valley and possibly Sumer too. as well as many advanced cultures, pastoralists and nomads that lived between those civilizations. So some of their beliefs and gods might have made it to Zoroastrianism and Hinduism. Indo-Iranian migrants from the steppes also contributed in some ways. Their languages became the language of Vedic and Zoroastrian scriptures. Maybe the beliefs of the native Indian people contributed to the earliest holy texts as well but I doubt that honestly. I'm talking about the AASI and ASI derived populations here of course (Pajeets).
Some academics claim that the Oxus civilization (BMAC) is where Zoroastrian fire veneration originates. As they had fire altars. But I'm a bit cautious of such claims since BMAC also had water altars, wind altars and other kinds of altars. Some think that the people that developed Zoroastrianism were politically opposed to the people that developed Vedic religion and vice versa. That's why their gods and devils were reversed. While others claim that's not true and that it's just that they had the same origin but evolved separately which is why they're similar but with a lot of differences. and I think that makes more sense.
what do you anons think?
