Mesopotamia was advanced because they invented the first system of writing. The first system of writing was called Cuneiform. They wrote everything on clay tablets. To write they used pictures and symbols. They could be written either horizontally or vertically. One cuneiform sign could have four meanings. Another reason that Mesopotamia was advanced is because they invented the wheel. The wheel was a very useful thing. They invented the plow after the wheel was made. The plow was needed for farming. For more information about the wheel click here: The third thing that makes Mesopotamia advanced is Hammurabis' Code. Hammurabis' Code is the first written laws. There was 282 laws. The Mesopotamians needed laws to make sure everyone is doing what they are supposed to be doing. Those are my three things that I think makes Mesopotamia advanced.
