Explanation: The first civilizations in the world developed around bodies of water, mostly around river valleys, or on islands and coastlines. From what is known so far, the earliest civilization developed in what is known as Mesopotamia, or rather the river valleys of Tigris and Euphrates. The civilization that arose here was the Sumerian civilization, which had a huge influence on the civilizations that developed later in the region and further.
The Sumerians are somewhat of a mystery, as their origin is still not known. There are several theories about them, but none has been proven. The Sumerians were very advanced for their time, and they set the basis in numerous scientific fields, as well as having numerous inventions. These people also are attributed to have been the first to have developed a writing system, the cuneiform.
