Most scholars agree that Zoroaster was a real person who lived long ago. No one is certain about the time when he lived. One estimate is that he lived about 3200 years ago, around 1200 BC. Some other estimates are that Zarathushtra may have lived anywhere between the 18th century BC and the 6th century BC.
