Basically, it's because nitrogen doesn't react easily with a lot of chemicals present in the earth's crust. Oxygen, however, does, so there's considerably less of it in our atmosphere and a lot of it locked up in solid compounds on and within the earth. So over the billions of years, it has "built up" in our atmosphere, and today comprises nearly 80% of the air we breathe.
