How do geologists think earth's atmosphere formed?

 1 In the beginning God created the heavens and the earth.

 2 Now the earth was formless and empty.darkness was over the surface of deep and the spirt of the God was hovering over the waters.

3 and God said let there be light, and there was light.

4 God saw the light was good and seperated the light from darkness.

5 God called the light day and the darkness night and there was evinigining and there was morning of the first day.

6 And God said let there be an expanse of water between the waters to separate water from water.
So god made the expanse and separated the water under the expanse from the water above it and it was so.
7 God called the expanse sky .and there was evening and there was morning the second day.
There that how the atmosphere was made.and that what geologist know too
