No. One of Saturn’s moons (Titan), may have an atmosphere made of nitrogen gas that making four-fifths of Earth’s atmosphere). However to stay alive that Human needs oxygen.
Is there life on other planets?
All of the planets in the Solar System have been explored with telescopes and space probes – So far, nothing living has been found. The other planets in our system all seem to be too hot, too cold or made completely of gases.
