Okay kiddo, do you know what writing is? It's when we use letters and symbols to make words and sentences to communicate with each other.
Now, a very long time ago, people didn't have the kind of writing we use today. They didn't have paper or pens. So they used something called cuneiform.
Cuneiform is a way of writing that was used in ancient times, in a place called Mesopotamia (which is now Iraq). Instead of using letters like we do, they used a sharp tool to make wedge-shaped marks on a piece of clay.
These marks represented different things like people, animals, and objects. They were arranged in rows to make sentences that told stories or kept records of important things like measurements or taxes.
Cuneiform was very important because it allowed people to keep records of things they needed to remember, like how much food they had, or how many people lived in their town. It also helped them tell stories and share information with each other.
So that's what cuneiform is, a special way of writing that helped people a long time ago communicate with each other and keep track of important information.
