This statement is incorrect. While cuneiform was indeed used to write religious texts, it served a much broader purpose in ancient Mesopotamian civilizations. Cuneiform, one of the earliest known writing systems, was used for a variety of administrative, legal, commercial, and literary texts.
It was employed to record economic transactions, maintain administrative records, write letters, document laws, and create literary works such as epic poems and historical records. This versatility made cuneiform a crucial tool for communication in different aspects of daily life in ancient Mesopotamia.
