The birth of early civilization occurred along the banks of the Nile River in Egypt, the Tigris and Euphrates Rivers in Mesopotamia, the Indus River in India and the The Yellow River in China beginning around 3000 BC. This happened in the above four places over the course of about a thousand years. The rich soils of these riverbeds provided the fertile environment necessary to allow early humans to abandon their nomadic lifestyles and settle in one area. As these people settled they developed communities which evolved into cities and these early cities gave rise to the development of religion, government and society, the elements of modern civilization. As people formed communities they began to develop common religious believes shared and practiced by all. These believes were largely a way for mankind to understand and make sense of geography, climate and the natural environment.
These beliefs provided a unified world view shaping the development of culture. As these agricultural centers emerged and grew into cities the development of Government became necessary to provide harmony and social order. Farming gave rise to surplus and trade and this in turn created the need for a written language, a method of accounting for inventories and transactions. Language then developed into a vehicle for logging the history, beliefs and cultural standards of these early civilizations.
The development of agriculture also inspired the invention of tools and implements. These started as rudimentary items of necessity, developed into more complex instruments and eventually evolved into higher forms of Art. The main factor leading to the rise of early civilization were the fertile riverbeds which gave mankind the opportunity to settle in one area, develop common religions, governments and social orders. These early settlements created the background and framework for the complex civilization in which we now exist.
