The first complex urban civilisation began in Mesopotamia between the Tigris and Euphrates rivers, about 4,000 BC. This region is known as the “cradle of civilisation” because it saw the earliest emergence of many characteristics of modern society.
While humans developed settled, agricultural lifestyles in other parts of the world, prior to 4,000 BC, Uruk and Ur in Mesopotamia are considered to have been the first fully developed cities.
The Mesopotamian people, the Sumerians, developed advanced irrigation, the wheel, and sophisticated metalworking, which allowed them to produce food surpluses and sustain large populations.
They developed cuneiform the first known script, around 3,000 BC to record transactions, literature, and laws.
Mesopotamian civilisation predates Moses at Mount Sinai by approximately 2,000 years. The Mesopotamians were deeply religious and polytheistic, believing in hundreds of gods and goddesses who controlled natural forces and human destiny.
