(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.

Even though, nitrogen is 4 times more abundant than oxygen in the atmosphere, we must also consider the relative abundances of nitrogen and oxygen over the entire Earth, where oxygen is about 10,000 times more abundant (water, sand). In life forms, nitrogen is less abundant than oxygen, mainly due to the abundance of water. Venus and Mars, though, have lots of CO2 in the atmosphere. Plant life on Earth (Ocean + Land) and precipitation have taken CO2 out of the atmosphere... plants created the oxygen reserve.
