There are basically four elements that make up the entire planet; earth, air, water and fire. Among these, water is the most abundant; it is present as rivers, lakes, and oceans globally. Research has shown that about 70% of the earth is covered with water, in addition to those packs of ice that are located far north. But the idea of water as a river or sea is limited, water can exist in more than a single form, and each should not be used to encompass the other. Other ways that water exists are as a gas, and as components of systems, whether living or otherwise. Water has been shown to be in the air we breathe, where it exists as moisture too.
Philosophically, those ideas about everything being made of water began many years ago, during the era of Greek Philosophy. Records of a postulation by the man who is now referred to as ‘the father of natural science’, holds that the entire essence of life is composed of water. The reason backing this idea was a fact that when water is left alone it exists as a liquid, if water gets boiled, vapor is formed, and if cooled a solid is produced. The ability of water to exist in three major forms that anything can exist promoted the idea that everything is made up of water.
Physically, we live in a world abundant of water, it is part of rocks, plants, air, and even the soil has moisture attached to it. Similarly, science has shown that the cells of all living things have water within them, which is necessary for survival even at that level. If the human cells are deprived of water, they shrink and die off, the same would happen to plants, including a number of micro-organisms. Therefore, if living depends on water, it would mean all things are made from it. But this theory is not true in its entirety, there are things that don’t have water in them.
Things like molten magma, which is more like liquid rock doesn’t have any water in it, fact is that any water around it would vaporize. There are other solidified rocks which don’t have water either, in addition to mercury, gasoline, ammonia, plastics and more. Evidence shows that when these items pass through the fire, you’ll clearly observe that there was no release of water vapor. Water is indeed abundant in nature, found virtually everywhere, but not everywhere.
