Of all the eight planets and Moons, why is life possible only on Earth?

Answer:

The Earth sustains life because it is the only planet just at the right distance from the Sun-hence it is neither too hot nor too cold. It also has the right mix of gases in the atmosphere for humans and plants. Also the availability of water and the tilt of the earth i.e., the axis which causes seasons and the water cycle sustain life.
