“...the sheer importance of spiritual light.”
Good point. And E=MC2, so the energy “light” would also include mass.
God has changed things in the natural world though after the seventh “day” of Creation. Prior to the flood there was no rain. A mist would rise up from the ground and water the plants.
Being in the earth sciences I can’t get my head around that one though, with the physical evidence of long-term erosion that we observe. I know that certain huge landforms can be created in a week due to geologic catastraphic events (such as collapse of glacial dams, etc.) But that is not typical of most land forms.
That goes beyond "Creation" and into "terraforming." See Walt Brown's Hydroplate Theory (click here)on that, if you haven't already.
