You cannot find oxygen and water in Saturn. This is a planet that is made up mostly of hydrogen and helium. It contains certain types of ice that is expected because it is already far away from the sun. It has some methane and ammonia. Based on the components of the planet, it is evident that life is not very possible.
Scientists are focusing more on the different moons of Saturn because they seem to have qualities that will make it possible for the moons to sustain life. One of Saturn’s moons, Rhea actually has an atmosphere that contains oxygen. Further research is being done to confirm this.
