Why was the area between the Mediterranean sea and the Persian gulf called the Fertile Crescent?

The area between the Mediterranean Sea and the Persian Gulf is called the Fertile Crescent due to its rich soils and favorable agricultural conditions, which allowed early civilizations to thrive. The region's unique shape resembles a crescent, and its access to water sources from rivers like the Tigris and Euphrates facilitated the development of farming. This agricultural abundance supported the rise of some of the world’s first cities and complex societies, making it a crucial area in human history.
