Archaeological culture is like a big puzzle that helps us understand how people lived in the past. Imagine you have a box of different toys - each toy is different and has its own special features. Just like those toys, ancient artifacts (like tools, bones, and pottery) are also different from one place to another.
Archaeologists use these artifacts to find clues about how certain groups of people lived in the past. So, just like how all the toys in your box might have something in common, the artifacts from a particular group of people can also tell us about their culture - how they made things, what they ate, and how they interacted with others.
For example, if some archaeologists found a lot of arrowheads and animal bones in one area, they might conclude that the people who lived there a long time ago were hunters. They might call that group of people the "hunter-gatherer culture." If another group of archaeologists found a lot of pottery fragments and evidence of agriculture (like grains and seeds), they might decide that the people who lived there were farmers. They might call that group of people the "farming culture."
So, archaeological culture is just a way to group together artifacts from the same time and place that give us clues about how people lived. Just like how putting the pieces of a puzzle together helps us see the bigger picture, putting artifacts together can help us understand the culture of a certain group of people who lived long ago.
