Are We Part of the Crass?

The earth was barren ad we had just a ball of rock with really no atmosphere to speak of. So at this period here where the earth is like naked, there's just no atmosphere protecting the surface of the earth from basically space. And that's where this outer gas layer of the crust that we call atmosphere came from when it was replenished. It was replenished from inside the earth, because volcanoes led to these explosions and eruptions which can produce enormous quantities of gas.
