It is said, and it is true, that “water is life”. This has also been proven scientifically: up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Even much so is our planet earth. It is mostly water. About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and so forth.
Furthermore, even our solar system contains water. Although some claim that Earth is the only planet with liquid water on its surface, in a study of more than 4000 exoplanets, a team led by Li Zeng, a planetary scientist at Harvard University in the US, found that fully 35% appear to contain up to half their mass as water.
In a recent study of the Cosmos, researchers say that water worlds are abundant in the universe. Therefore to a great extent, water is everywhere in creation. But the Luos of Egypt took the value of water further than just to drink and live.
In a sense then, the Nile water became everything for man to live. It was not only the center of political and military power, but also for cultural and social development as well as an economic engine of growth and survival for the people. A recent film, HAPI documentary demonstrates this aspect of the Nile.
Therefore, to a great extent, the Nile linked everything: culture with spirituality, economics and politics, government and sociology, and much more. Without water, nothing survives in the world. It is the key to spirituality and economic development.
