This document provides an overview of the emergence and development of early civilizations. It discusses how approximately 10,000 years ago, humans began cultivating plants and herding animals, allowing some to live sedentary lives. Around 5,000 years ago, humans learned to control river waters, enabling richer harvests and population growth. The earliest civilizations formed in river valleys, inventing practices like writing, metalworking, cities, complex religions, and social hierarchies. The document then examines specific early civilizations like the Sumerians, Egyptians, and Israelites in greater detail.
