No, the Nitrogen in the air has probably always been there (because nitrogen is rather inert), but originally Earths atmosphere was reducing (it had no free Oxygen) and probably contained large amounts of CO2 and hydrocarbons. The present atmosphere on Earth is the product of biological processes which have slowly introduced free Oxygen into the Oceans and then the atmosphere - life made Earth habitable for life!
