Why are the four ancient civilizations in Asia and Africa all produced in the great river basin?

1. There are sufficient irrigation water sources, rich water resources, flat terrain and fertile land.

2. The large river basin has a mild climate, which is suitable for human survival and is conducive to crop planting and growth.

3. In primitive society, the conditions of water diversion projects were relatively bad, and the river area was the easiest to divert water for irrigation.

It is easy to plant vegetation and raise animals. In the long run, it is much less difficult to engage in agriculture than in hilly areas.

5. The village construction that is beneficial to farming will eventually evolve into a town where people gather, and a splendid civilization will be born.

Extended data:

Water is a nutrient that nourishes the growth of all things. The flood or water shortage caused by the drastic change of weather and climate is also stirring the waves of human civilization and affecting the fate of mankind.

The four ancient civilizations, ancient Egypt, Babylon, India and China, all originated in the great river basin, which is the best evidence of this interdependence. According to research, ancient agriculture was dominated by annual millet and millet crops.

The climatic conditions in ancient Egypt, Babylon, India and China are similar, which is very beneficial to the growth of millet crops such as millet and wheat.

In the big river areas with four ancient civilizations, something similar to the high tide of the river will happen every year. A large number of rivers bring fertile soil to the river bottom, which is very beneficial to the growth of crops, so it promotes the development of agriculture in this area.

The prosperity of agriculture has naturally laid a strong foundation for economic progress, and economic progress has also created various large, medium and small cities, and the nature surrounding it is the next major ancient civilization.
