Did Persians believe in gods

Answer 1

Yes. But, it is unclear who their gods were? One thing is certain, while that culture of their's from back then was originally polytheistic and similar to Hinduism, it was not Hinduism, and it was not Mesopotamian/Babylonian polytheism either. Whatever the names of their gods were, and whatever they were capable of, though, remains unclear.

Answer 2

Zoroastrianism is believed to have arrived in Persia from eastern Iran, sometime in the seventh century BCE. When they first made contact with the Jews of the Babylonian Exile, the Persians were monotheistic, believing in the Zoroastrian god Ahura Mazda ("Wise Lord"). Arguably, their beliefs may have influenced later Jewish beliefs.
