Life requires certain elements–one of which is oxygen. To live, we must have energy and our life-energy is produced by chemical reactions requiring oxygen. Because of the oxygen level of Earth, we can breathe easy.
When oxygen combines with other elements and compounds, we call the process oxidation or combustion. Oxidation results in the release of energy. Oxidation can be slow as when oxygen combines with iron to form rust. Oxidation can be fast, as when oxygen combines with chemicals in wood, producing fire.
The rapid combustion process releases energy in the form of heat and light. In our bodies, oxygen combines with other chemicals more slowly. As oxygen combines with sugar (glucose) in our cells, energy is released warming our bodies and powering our cells. The by-products of this oxidation are carbon-dioxide and water, which can be safely eliminated from the body.
The design of the oxygen molecule with its ability to pull off electrons from other elements makes combustion possible. Are there other chemicals which can produce combustion? Yes, chlorine, fluorine, and bromine can also produce combustion. However, the by-products of that combustion, such as hydrochloric acid, would be harmful or fatal to living cells. Oxygen has just the right properties to combine with carbon-based sugars in our cells to release energy and sustain life without producing compounds harmful to life.
The fact that one-fifth of our atmosphere is oxygen enables us to breathe efficiently. A lower level of oxygen would make breathing difficult. A higher oxygen level would lead to a greater danger of rapid-combustion fires. Replacing oxygen in the air with other combustive elements would be destructive to life. Oxygen has the right properties and is available in the right amount to allow us to breathe easy and live. We think a Master Engineer designed this system.
