I did not say 70 metre of additional water from ice melt is going to solve any problem. The entire problem you attempt to raise is a construct of your own doing...not mine!
No, the problem arises from the geological and hydrological nonsense you find yourself in if you take the bible as accurate history ─ as everyone but YECs can see at a glance, apparently.
New research suggests ancient Earth was a water world, with little to no land in sight. And that could have major implications for the origin and evolution of life.
That hypothesis is about the earth as it existed very shortly after its formation some 4.5 billion years ago. No geologist of any repute relates it to the world as it existed in the third millennium or so BCE, where the Flood story comes from ─ a thousand years or so before the god of the bible appears in history.
1, Both world views agree that plate techtonics are responsible for mountain range uplift...so once upon a time, Everest was not 8km high!
Yes ─ as I showed you, something like that may have been the case 70 million years ago.
Your entire claim about the need for billions of cubic metres of aditional water is mute!
No, I've given voice to it. You live in Mesopotamia in the third millennium BCE. Water appears out of nowhere and drowns Mesopotamia under something like 5 miles of water, just enough to put say 20 feet of water above the tip of Mt Everest. How much more water do you need to achieve this, over and above the water presently on the earth? I set out the sum earlier in this thread ─
Volume of the earth, radius center to mean sea level plus ~30,000 feet
minus
volume of the earth, radius center to mean sea level
minus
volume of land above mean sea level.
And you've done the sum, so you know you need about 1.113 billion cubic miles of water over and above the water presently on the earth.
It ain't rocket science, just high school arithmetic you can do on your pocket calculator.
Now where's your explanation of "the fountains of the deep" and where do we find examples of them?
And how can you make them cover the earth with all the water mentioned above, given the problems I spelt out for you in my previous post?
And where's that universal geological flood layer left by the Flood?
And where are those genetic bottlenecks in every species of land animal, all dating to the same date as the flood layer?
After all, if the Flood actually happened, ALL those things MUST be out there.
