“Watered covered mountains up to 4200 meters? Where did it all go?”
I would imagine it went back to where it came from: Inside the earth. “And the fountains of the great deep opened....”
So, the earth was hollow, and now contains water which has the volume of 4200 meters by the circumference of the earth? I guess we’ll never get thirsty. I wonder why we never come across water in that amount when drilling for water, we could grow wheat in the sahara.
