Imagine you and your friends are playing a game where you have to dig in your backyard to find old stuff from the past. You find a lot of things like broken toys, empty cans, and maybe even an old coin. But what if you found something really old like a dinosaur bone or a hidden treasure?
Archaeologists are like grown-up kids who play this game, but on a much bigger scale. They dig in different places all around the world to find old things that humans used or made a very long time ago. They even find the remains of ancient cities, temples, and tombs.
When they find something old, they want to know exactly how old it is. They use a special tool called a radiocarbon dating machine to determine the age of the object. Based on these findings, archaeologists can create a table of years in archaeology, which tells us when different things in history happened.
For example, the table might say that 3000 BC is when the ancient Egyptians built the pyramids or that 1066 AD is when William the Conqueror invaded England. This makes it easier for historians to study and understand different periods of history.
So, in summary, a table of years in archaeology helps us understand when important events in history happened and how old different objects and buildings are.
