What does our atmosphere do that makes conditions on Earth suitable for life?
You have it wrong way round, the atmosphere of Earth was created by the life on Earth. 4000 million years ago the atmosphere had no oxygen and was full of CO2, Nitrogen and Methane. However life came into existence in this atmosphere and over time has altered the atmosphere to what we have today. Therefore the composition of the atmosphere would not appear to be critical to life.
