How Deep was Noah’s Flood?

The waters prevailed and greatly increased on the earth, and the ark moved about on the surface of the waters. And the waters prevailed exceedingly on the earth, and all the high hills under the whole heaven were covered. The waters prevailed fifteen cubits upward, and the mountains were covered.

(Genesis 7:18-20) NKJV

There was enough water in the great deep to flood the Earth 1,200 km deep. 15 cubits was when the crew of the ark stopped taking soundings. Mount Everest formed 101 years AFTER Noah’s flood during Peleg’s tectonics.

This post is a response to, and a rebuttal of: How much water would be needed for Noah’s Flood? by Andrew L. Seidel. He posted the link in a Twitter thread discussing our post do I still need to ask for forgiveness?

We all have the same evidence. Our choice of paradigm determines what we think it’s evidence of.

Matty’s Razor

A lot of people like to say that there’s not enough water on Earth to flood it to a depth of 15 cubits above all mountains. They use math to do this so, naturally, everybody believes them because, hey, it’s math. These people presume to disprove God by cobbling together some math based on ideals that were popularized by Charles Lyell, a contemporary of Charles Darwin known as 19th Century Uniformitarianism. It’s the belief that Earth has been so stable for so long that conditions of the present day are a sufficiently accurate indicator of conditions in the past.

Nothing could be further from the truth. We (that’s me and the Holy spirit) are going to show you that there was enough water available to flood the Earth more than 1,200 km deep. There are several reasons why math-based flood-deniers aren’t in the right ball park:

  1. The great deep, the supposed outer core, was full of water,
  2. An extra-terrestrial source of water was part of the event,
  3. The Earth’s radius has shrunk since the time of the flood,
  4. The highest mountains on Earth, the Himalayas, formed in Peleg’s tectonics 101 years AFTER Noah’s flood.

Faith is believing in something that you can’t see, because of evidence.

21st Century Apologetics

Welcome to Christian apologetics in the 21st Century. We can refute the rationale behind how the mass of the Earth has been derived based on gravitational interaction. Earth can have a great gulf of open space in the region of the outer core and we can have functional orbital mechanics.

Most Christians, like everybody else, think that mainstream science (SciPop) has figured out that hell isn’t at the center of the Earth but very few know how it was done. Some folk understand the gravitational methods which have been used. We can apply our Biblical theory of gravitation here. We developed our rationale in response to push back from a compromised Christian in where is the gravity in a comet? This brings us to look at new ways for Christians to make fools of themselves in passive aggressive special pleading.

The reason for creation is the manifestation of sentient life with free will.

Noah’s Math

The waters of the great deep flooded the Earth to a depth that may be calculated by adding its volume to the volume of the pre-flood Earth, and calculating the radius for a sphere of this volume.

FactorSymbolValue m3
Volume of Earth on the 3rd dayt1.88E+12
Volume of water in the great deepw1.06E+12
Total volumet+w2.94E+12
– Calculating the total volume of Noah’s flood. A volume of 2.94E+12 m3 corresponds to a sphere of radius 8,883 km. If the diameter of the pre-flood Earth was 7,653 km, then the waters of the great deep alone would have flooded the Earth to a depth of 1,230 km. That doesn’t include the waters above the firmament.

So, just because a bunch of flood-deniers can wave some math around, don’t believe it. We’re going to walk you through Noah’s math in a series starting with present day earth. We calculate that there was enough water in the great deep to flood the Earth 1,200 Km deep. It would appear that the crew of the Ark stopped taking soundings at 15 cubits. That was the longest rope that they had.

What can we say to the atheist science trolls (ASTs) scientifically illiterate science worshipers (SISWs)and SciPop devotees who want to use 19th Century Uniformitarianism to say that there isn’t enough water on the Earth to flood it higher than Mt. Everest? You’re 200 years behind the times. This is the 21st Century, go find something else to do because you’re making fools of yourselves.
