Aeon

philosophy religion Maturity 11-13 Next article →

An aeon is a way to talk about time. It can mean a very long period. The word comes from an old Greek word. That word once meant one hundred years. Today, people use it for any long time.

Scientists use the word in different ways. In space science, an aeon is one billion years. Geologists use it to group Earth's history. They use four main aeons. These are the Hadean, Archean, Proterozoic, and Phanerozoic.

Many religions also use this word. In Hinduism and Buddhism, an aeon can be a kalpa. A mahakalpa is a cycle of the world. Some say it lasts over one billion years. But these numbers are often symbolic.

In Gnosticism, aeons have a different meaning. They are parts of God that come out from the One. These parts have many names. Some call them wisdom or the beginning. In Christianity, some people think of aeons as ages. They may think of an age to come. This is a way to talk about life after death. It is a big word for very big ideas.
