Similarity of natural environment: the great river basins in ancient North Africa and Asia had vast fields and convenient irrigation, and the unique farming environment created good conditions for human survival. Impact: Ancient residents worked in these areas for a long time, so the river basin became the birthplace of human civilization. Ancient river basins were characterized by agricultural civilization. Agriculture is the most important production sector in these areas, and it is also the economic foundation for the formation and development of countries in these areas. Ancient Asian and African civilizations, such as ancient Egypt, Babylon, India and China, were established and developed on the basis of agricultural economy, and showed their own civilization characteristics. Oriental village community is the grass-roots social organization in the river basin, and centralization is the main form of state rule in the river basin.
