Step-by-step explanation:
Zoroastrianism, founded by the prophet Zoroaster (also known as Zarathustra), introduced several distinctive elements that set it apart from religions that came before it. While it is true that Zoroastrianism discussed an afterlife and emphasized the existence of heaven and hell, this concept was not entirely unique to Zoroastrianism, as other religions before it also had beliefs about an afterlife. Additionally, Zoroastrianism was not polytheistic but rather a monotheistic religion, centered around the worship of Ahura Mazda as the supreme deity.
