The universe consists of:
1. hydrogen (H) 70.0 %;
2. helium (He) 28.0%;
3. oxygen (O) 0.92 %;
4. carbon (C) 0.34 %;
5. nitrogen (N) 0.12 %.
All living creatures on Earth are created by this elements, without helium. The most abundant in the universe is the hydrogen! In Latin "Hydrogenium", derives from the Greek words "hydro" - water and "genes" - born. Hydrogen on the Earth is most abundant in water and forms of chemical compounds such as hydrocarbons.
In General all this elements are also known as the four elements of life: water (hydrogen), fire (oxygen), earth (carbon) and air (nitrogen). The Earth atmosphere (the garden of life) is consisted from 78% nitrogen and 21% oxygen. And we also know that when something burns it oxidize. The marriage of this two (nitrogen-oxygen) are one part of the conditions of life, and water with carbon are the other part where water is the dominant element, so this is why Earth is known as watery planet.
The chemical combination is taking place thanks to carbon, only carbon atoms have four arms for bonding and are able to combine with hydrogen, oxygen, nitrogen, and carbon in various manners. As a result, a variety of organic molecules with different chemical reactions and functions would be created. It is, however, not easy to bond small molecules together and create polymers. External energy or some catalysts are necessary to do that. So this organic molecules are combined in Polymers and this Polymers gather together and create the functions of life. The organic molecules, whose main structures are made of carbon atoms, seem to polymerize and become complicated polymer substances such as protein and DNA.
In plain English: Humans are created from big amount of oxygen, carbon, hydrogen, nitrogen and other smaller amounts of other elements and compounds. A child life before is born starts in water for 9 months where goes through the entire evolution of life that is found on Earth and is born as Amphibian. This combination is the most complex organ combined with all this ingredients that are part of everything in this Universe. This complex community does not last long, but while lasts the manager (WE/OUR SELF) should give it an unconditional-great time full of life. The most usual communication with this system is the instinct, intuition, inner voice, guts, hart, soul and etc. Everything else is orders by the manager...
