Which of the following ancient civilizations is known as "the land between 2 rivers"?

Mesopotamia is known as "the land between 2 rivers" because it is situated between the Tigris and Euphrates rivers in modern-day Iraq. This region is widely considered the cradle of civilization, where some of the earliest known cities and complex societies emerged. The fertile land around these rivers supported agriculture, which allowed for population growth and the development of urban centers, writing, and various forms of governance. The significance of Mesopotamia also lies in its early contributions to human history, including the invention of writing (cuneiform), advancements in mathematics, and the establishment of legal codes, such as those attributed to Hammurabi.

In contrast, the Indus Valley civilization is associated with the Indus River, while China is linked to the yellow river, and Egypt is known for the Nile River. Each of these civilizations developed independently along their respective river systems but does not share the same geographical description that defines Mesopotamia.
