Archaeology is like a big treasure hunt! But instead of looking for gold or jewels, we look for really old things buried underground. These things can help us learn about how people lived a long, long time ago.
Archaeologists use special tools like shovels, brushes, and even little brushes to carefully dig up these old things. Sometimes they find broken pieces of pottery that people used to eat and drink from a long time ago. Sometimes they find old bones from animals that lived a long time ago. And sometimes they even find really old tools that people used to make clothes, build houses, or hunt for food!
Once archaeologists find these things, they clean them and study them really carefully to learn more about how people used to live. They can even tell how old the things are by using special machines and measuring things like how much the object has decayed.
And by learning about how people lived a long time ago, archaeologists can help us better understand how our world has changed over time!
