There's a glitch in the story for pro and con. Both sides are 'assuming' that the earth at the time of the flood looked than geographically as it looks today topside and sea floor wise.<quoted text>
I have researched it :-
The amount of water on earth is known, roughly 1,260,000,000,000,000,000,000 litres. Around 1,260,000,000 cubic kilometres of water
The oceans average around 800 metres deep, approximately 0.36% is found underground and 0.035% is found in lakes, rivers, clouds etc.
In the past I have calculated how much water would be needed to cover the earth to a depth of 9 metres (approximately 20 cubits) above the highest mountain (Everest at 8.8km high) as specified in the Noah story,
You need approximately 5,655,678,336,000,000,000 cubic kilometres of water or 5,655,678,336,000,000,000,000, 000,000,000 litres
I believe that is around 4,488,633,600 time more water than is actually available
Admittedly that does not take account of landmass, hills, mountains etc but even taking the worse scenario that all land mass is as high as Everest (which of course it isnít) then you are still looking 3,000,000,000 more water than there is
That the world just somehow flooded itself without any physical trauma as in volcanic action/earthquakes.
The writer actually describes something they should not have even been able to have guessed correctly that science has shown actually takes place on the sea floors today. "...all the fountains of the great deep broken up,.." The writer is actually describing water being pushed up by volcanic action through the crust of the earth through the sea/ocean/lake floors to add more water to what already exists topside.
The point shouldn't be whether an invisible being caused this to take place. The point to be wondered about is how the writer was able to describe volcanic activity that takes place miles to thousands of feet below ocean and sea water levels. A volcanic heated vent on the ocean floor large or small spills out vast quantities of heated water. Volcanic vents on land don't usually do this in the same manner as on the oceans floors that this writer would have been privy to have seen to have written about. So how did they make a best guess and guess it correctly?
