(floating cities). There is only one planet where gaseous oxygen is found: Earth! And the only reason that Earth has oxygen is because Earth has plants that do photosynthesis. There is no other natural process that we know of that will put significant amounts of oxygen into a planet's atmosphere.o that is bad news if you'd like to live on another planet in our Solar System. However, it does mean that if we ever find a planet around another star that has oxygen in its atmosphere, we can be fairly confident that there is life of some kind on that planet.

Photosynthesis from plants use carbon dioxide, sunlight, and water and a byproduct is oxygen. Before humans existed, the earth existed for millions of years creating an enormous supply of oxygen. Organisms and plants created a balance of oxygen and CO2. The Earth's net supply of oxygen comes from phytoplankton. Plants produce oxygen but use up what they make by producing carbon dioxide at night and when they are burned or decompose, so you see, the only thing that keeps us breathing is the tiny phytoplankton in the sea.
