Step-by-step explanation:
Zoroaster, also known as Zarathustra, brought a new religion to Persia called Zoroastrianism. His teachings would go on to influence Judaism and Christianity. Zoroastrianism is a monotheistic religion that centers around the belief in a god of goodness and light, Ahura Mazda, and the constant struggle between good and evil.
