The Earth's atmosphere that we know today originated millions of years ago when volcanic activity released materials from the Earth's crust. These were mainly: H2O, CO2, N2, and sulfates. Through the passage of time and adjustments in the atmosphere, a lot of CO2 was converted by plants and algae into oxygen, while N2 remained because it is inert.
