Determining the oldest language in the world is a complex task as languages evolve and change over time, and the origins of many ancient languages are still debated among linguists and researchers. However, one language often mentioned in discussions about ancient languages is Sumerian. Sumerian is an ancient language that was spoken in Mesopotamia (modern-day Iraq and parts of Iran) as early as the 4th millennium BCE. It is considered one of the earliest known written languages and was used by the Sumerian civilization, which thrived in the region. The earliest written records in Sumerian date back to around 3200 BCE. Other ancient languages that are often mentioned in discussions about the oldest languages include Egyptian, Akkadian, Elamite, and Hittite. Each of these languages has a rich history and dates back to ancient times. It's important to note that the concept of “the oldest language” is complex and subject to ongoing research and discoveries. Our understanding of ancient languages continues to evolve as new evidence is uncovered through archaeological findings and decipherment of ancient scripts.
