The short answer isâ¦yes! Carbon atoms form the âbackboneâ of almost all the important biological molecules floating around in our bodies (except water, of course.)

Oxygen is not the main constituent of Earth's atmosphere, comprising 21% of the total compared with Nitrogen's 78%, but its role in the survival of many forms of life elevates its significance.f methane was an important greenhouse gas for the early Earth, the presence of oxygen, which very quickly destroys methane molecules, would have cooled the planet significantly for a time. Of course, in the long term, the rise of oxygen has benefited life hugely.
