What was the worlds first system of writing called

The world's first system of writing is called cuneiform. It was developed in ancient Mesopotamia (modern-day Iraq and Syria) around 3400 BCE. Cuneiform was created by the Sumerians and later used by other civilizations in the region, including the Babylonians and Assyrians. The term "cuneiform" comes from the Latin word "cuneus," meaning wedge, as the script consists of wedge-shaped marks made with a stylus on clay tablets.
