How did the geography of the fertile crescent affect the development of civilizations there

Sources:

Named for its rich soils, the Fertile Crescent, often called the “cradle of civilization,” is found in the Middle East. Because of this region’s relatively abundant access to water, the earliest civilizations were established in the Fertile Crescent, including the Sumerians. Its area covers what are now southern Iraq, Syria, Lebanon, Jordan, Palestine, Israel, Egypt, and parts of Turkey and Iran. Two rivers, the Tigris and the Euphrates, regularly flooded the region, and the Nile River also runs through part of it. Irrigation and agriculture developed here because of the fertile soil found near these rivers.

Access to water helped with farming and trade routes. Soon, its natural riches brought travelers in and out of the Fertile Crescent. This led to an exchange of culture and ideas, and advancements in the region as writing (cuneiform), math, and religion all soon developed there.
