The most important for us is oxygen which allows us to.....LIVE!!=] Then there's carbon dioxide which allows plants to use photosynthesis. Then there's ozone which prevents ultraviolet light from penetrating the atmosphere in too large an amount and finally there's water vapour which (along with carbon dioxide) acts as a greenhouse which is important in allowing the planet to maintain a temperature which is necessary to species' on earth.
Life on Earth is possible because the atmosphere, and the whole environment, is suitable to support life.

Liquid water, a suitable mix of atmospheric gases, proximity to the sun, the magnetosphere, Earth's size; all make life possible on Earth.
If there is a possible hole in the ozone layer, it could make the Earth hotter and start to melt glaciers.

Three things that make life on Earth possible are; water, temperature, and the atmosphere.
without it there would be no air and the sun's deadly UV rays could not make life possible

Scientists study the characteristics that make life on earth possible so they can figure out when life will know longer be possible. They also want to know what causes life to not be possible.
Atmosphere makes huge efforts. It is the one because of which life sustains.

the atmosphere, mild temperatures, and liquid water
Life. Earth has an atmosphere that's rich in oxygen, and a lot of water.
