Isn’t it interesting how the theme of conflict between good and evil recycles throughout much of history, even though each cycle seems to have different twists. The following quotes are from Wikipedia.
Manichaenism: “A key belief in Manichaeism is that the powerful, though not omnipotent good power (God), was opposed by the eternal evil power (devil). Humanity, the world, and the soul are seen as the by-product of the battle between God’s proxy, Primal Man, and the devil.” Manichaenism prospered between the 3rd and 7th centuries CE.
Zoroastrianism: " Zoroastrianism has a dualistic cosmology of good and evil and an eschatology which predicts the ultimate conquest of evil by good. Zoroastrianism exalts an uncreated and benevolent deity of wisdom, ( Wise Lord ), as its supreme being.The unique historical features of Zoroastrianism, such as its monotheism, messianism, judgment after death, heaven, and free will may have influenced other religious and philosophical systems, including Second Temple Judaism, Gnosticism, Greek philosophy." Zoroastrianism hung around for more than a thousand years.
