The Avestan period was a really long time ago, like way before there were cars, TVs or even iPhones. Back then, people spoke a language called Avestan and they lived in a place called Iran.
During the Avestan period, people believed in a religion called Zoroastrianism, which was all about good vs. evil. The good god was called Ahura Mazda, and the evil god was called Angra Mainyu. Zoroastrians believed in being kind, honest, and helpful to others, and they had special prayers and rituals they performed to show their devotion to their gods.
One of the most important texts of this time was called the Avesta, which was a collection of religious writings that explained the beliefs and rituals of Zoroastrianism. There were many important people who contributed to the Avestan period, including religious leaders, scholars, and poets.
Overall, the Avestan period represents an important time in history when people were trying to understand the world around them and find meaning in their lives through religion and spirituality. Today, many people still practice Zoroastrianism and study the texts and traditions that originated during the Avestan period.
