Zoroastrianism is one of the oldest religions in the world. It was founded by the prophet Zoroaster in ancient Iran approximately 3,500 years ago. Zoroastrianism is a monotheistic religion and believes in one God, Ahura Mazda. Zoroastrianism is also a dualistic religion. This means that it believes in two equal and opposite forces, good and evil. Zoroastrians believe that humans are free to choose between these two forces. Zoroastrianism is also a eschatological religion. This means that it believes in the ultimate end of the world and the ultimate fate of humans. Zoroastrians believe that there will be a final battle between good and evil, and that the side of good will ultimately triumph.
