History of the world
Whether in prehistoric or historic times, people always needed to be near reliable sources of potable water. Settlements developed on river banks as early as 3000 BCE in Mesopotamia, on the banks of Egypt's Nile River, in the Indus River valley, and along China's rivers. As farming developed, grain agriculture became more sophisticated and prompted a division of labour to store food between growing seasons. Labour divisions led to the rise of a leisured upper class and the development of cities, which provided the foundation for civilization. The growing complexity of human societies necessitated systems of accounting and writing.
Herrera Period
Agriculture started around 5000 years before present which led to the development of more complex societies, of which the Herrera Period is one of many in the Andean civilizations. Early evidence of inhabitation has been found in Zipacón and is dated at 3270 BCE. From the Herrera Period ceramic has been found. The oldest ceramic evidence found dates to 2500 BP (500 BCE), except for one piece found near Tocarema and dated at 2750 BP.
