Discussion pre history and early civilizations

Only four ancient civilizations—Mesopotamia, Egypt, the Indus valley, and China—provided the basis for continuous cultural developments in the same location.Pre-history is the fact of origin of human activities and civilization thousands of years ago. In general, prehistory is divided into 3 ages and hence the name was given ” A 3 Age System”. The 3 ages are Stone Age, Bronze Age, and Iron Age. These 3 ages give pieces of evidence of human activity in ancient times.The advent of civilization depended on the ability of some agricultural settlements to consistently produce surplus food, which allowed some people to specialize in non-agricultural work, which in turn allowed for increased production, trade, population, and social stratification. Early civilizations arose first in Lower Mesopotamia (3000 BCE), followed by Egyptian civilization along the Nile River (3000 BCE), the Harappan civilization in the Indus River Valley (in present-day India and Pakistan; 2500 BCE), and Chinese civilization along the Yellow and Yangtze Rivers (2200 BCE).
