Zoroastrianism: one of the world's older organized faiths

Zoroastrianism emerged in Persia (modern-day Iran) around 600 years BCE and has influenced some aspects of Judaism, Christianity, and Islam, particularly in the areas of afterlife, judgment, angels, and the end of the world.

Zoroastrianism teaches that there is a cosmic struggle between the forces of good (represented by the god Ahura Mazda) and the forces of evil (represented by the demon Angra Mainyu or Ahriman). This dualistic worldview has been compared to the Christian concept of God and Satan, and the Jewish concept of yetzer hatov (inclination towards good) and the yetzer hara (inclination towards evil).
