Earth is the only planet that is capable of supporting life as we know it due to the presence of temperature, oxygen, an atmosphere and energy.
All the above contribute in the following ways;
Atmosphere - The atmosphere is sort of like a protective barrier around earth. It destroys a lot of foreign objects that fall on earth and traps the sun's rays such that we keep us adequately warm. It also contains both oxygen and carbon dioxide which living things rely on.
Energy - The presence of energy sources on Earth enables us to be able to survive. Energy sources like fire, water, and solar enable us to do things such as cooking and electricity generation, that ensure our survival.
Nutrients - The nutrients available on Earth ensure that living things can grow and survive.
Temperature - A very important factor, Earth has the right amount of temperature necessary for the proliferation of life. It is not too cold that living things are unable to metabolize food and freeze and is not too hot that life cannot survive.
