After re-reading Gensis one evening, a picture came to mind.
In the begining God created the heaven and earth................and the earth she-became chaotic and vacant and darkness was on the surface of the submerged-chaos (i'm loosely quoting from the interlinear).
Now, for discussion, is the universe encased in a shell of water?
And God said, he-shall-become atmosphere (expanse) in-midst-of waters and he-shall-become seperation between waters and-waters.
Image millions of miles of water deep covering the earth (and perhaps enough matter to make all else, either way).
Now in verse 14 of Gen. it says that he created the luminaries in the atmosphere (expanse) that earlier was created by seperating the waters from the waters.
What do you think?
