Axial age is a fancy term that people use to talk about a time long ago when many different cultures and religions began to develop and change in big ways. It was like a really important turning point in history, just like when you learn to ride a bike without training wheels, it's a big change!
During the axial age, people started to think more deeply about why we are here and what is our purpose in life. They also started to think about how we should treat each other and the world around us. They created new ideas about things like justice, equality, and love. These ideas became the foundation of many religions like Buddhism, Christianity, and Confucianism.
It was a time when many important people like Buddha, Jesus, and Confucius came to be and their teachings had a big impact on the world.
So, think of the axial age like a really important moment in the history of the world, when people were coming up with big ideas that have shaped the world we live in today.
