The oldest written language is:

The oldest known written language is Sumerian, which emerged in ancient Mesopotamia around 3100 BCE. It was recorded using the cuneiform script, a system of wedge-shaped marks pressed into clay tablets. Initially developed for record-keeping, trade, and administration, Sumerian gradually evolved into a complex written language capable of expressing abstract ideas, laws, literature, and religious texts. Although Sumerian eventually ceased to be spoken as a native language around 2000 BCE, it continued to be used for scholarly and religious purposes for centuries. Its preservation provides historians and linguists with valuable insights into the earliest phases of human civilization.
