The original atmosphere may have been similar to the composition of the solar nebula and close to the present composition of the Gas Giant planets, though this depends on the details of how the planets condensed from the solar nebula. That atmosphere was lost to space, and replaced by compounds outgassed from the crust or (in some more recent theories) much of the atmosphere may have come instead from the impacts of comets and other planetesimals rich in volatile materials.
The oxygen so characteristic of our atmosphere was almost all produced by plants (cyanobacteria or, more colloquially, blue-green algae). Thus, the present composition of the atmosphere is 79% nitrogen, 20% oxygen, and 1% other gases.
But the raw materials of atmosphere is still from GOD>..
GOD made the atmosphere coz GOD knows we need it...
and GOD loves us...

The earth probably stole it from the moon which has no atmosphere of its own anymore. Maybe the Earth got it from Mars which also doesn't have an atmosphere anymore. Maybe the Martians brought it with them when they came here to be closer to the sun as there planet cooled and all the poon tang canals froze and the insects all went deep underground.

It was blown out by volcanic activity before the surface of the earth was cool.
