The earliest known writing system of sumerian.

Question: The earliest known writing system of sumerian.

The earliest known writing system of the Sumerians is cuneiform. Developed around 3500 BCE in southern Mesopotamia (modern-day Iraq), cuneiform began as pictographs and evolved into a system of wedge-shaped marks on clay tablets. It was used to record various aspects of daily life, including transactions, laws, and literature, such as the famous Epic of Gilgamesh.
