Analysis:

Water is directly related to the formation of culture. Water is the source of life. Without water, there is no life. Water has given human beings a source of food and clothing, and also a disaster of floods and famines.

The culture of water is the oldest culture of mankind, and rivers and water will become the source of inspiration for writers and poets at any time. Many literary masterpieces and popular poems are marked with rivers and water. Water and human beings are always interdependent. In order to eliminate floods and promote water conservancy, people should strengthen contact. In the practice of eliminating pests and promoting benefits, on the one hand, a large number of water conservancy projects have been built, and at the same time, rich experience has been gradually accumulated, forming a culture related to water activities.

Throughout the ages, water conservancy has not only created huge material wealth for society, but also created valuable spiritual wealth for society. As far as material wealth is concerned, from the development of animal husbandry to the bumper harvest of agriculture, from the invention of steam engine to the revitalization of modern industry, it is inseparable from the role of boiling water. It can be said that all social wealth created by human beings contains people's labor accumulation in water control and water use. As far as spiritual wealth is concerned, people have formed unique ideas and feelings in the process of dealing with water, thus creating many myths and legends, folk stories, poems and songs, painting and photography, folk art and drama, literary works and scientific writings with water as the theme. Therefore, no matter from the material wealth or spiritual wealth, water and culture are closely related. Water culture based on the relationship between water and people is an important part of human culture.

As far as the four ancient civilizations are concerned, I only know that ancient Greece developed navigation because of its small territory and large population.
