Explanation:

Earth's atmosphere makes life possible on Earth. It traps sunlight which raises the temperature of the Earth making it habitable without which the earth would be too cold to survive. The atmosphere contains gases such as Oxygen, carbon dioxide and nitrogen which are very important for survival.

Thus, due to atmosphere, Earth's temperature is steady, and presence of gases like oxygen makes it habitable.
