The original creation was very different than what we see today. There was a layer of water or ice above the atmosphere. “And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament (where the birds fly. V. 21) : and it was so.” Genesis 1:7 There was also a layer a water under the earth’s crust.  “The earth is the LORD’s, … For he hath founded it upon the seas, and established it upon the floods.” Psalms 24:1  “To him that stretched out the earth above the waters:” Psalms 136:6  More on seminar part 2 about this.  Picture courtesy Dr. Carl Baugh
