Where was it Originally written in cuneiform?

Cuneiform, one of the earliest systems of writing, was originally developed by the Sumerians in ancient Mesopotamia, around 3200 BCE. This writing system was primarily used in the city-states of Sumer, such as Uruk and Ur, to record various administrative, economic, and literary texts. Cuneiform was inscribed on clay tablets using a reed stylus, and it evolved over time to accommodate various languages, including Akkadian and Babylonian.
