Mesopotamia is generally credited with being the first place where civilized societies truly began to take shape. People around the world had been developing the groundwork for civilization for millennia: Agriculture was established around 8000 B.C. The domestication of animals for labor and food develop­ed simultaneously .People had been creating art for thousands of years already. Early laws had been established in the form of mores and folkways. All of these were parts of human culture, but not civilization. Mesopotamians refined, added to and formalized these systems, combining them to form a civilization.his achievement alone is significant, but their collection of written stories is just the beginning. With a sede­ntary lifestyle based on agric­ulture, spiritual practices that once were spread out became more centralized and refined, leading to organized religion.

For these reason mesopotamian civilization is called as the cradle of civilization.

Because it has the earliest writing, and thus the earliest records.
