Biblical Understanding for Nonbeliever Knuckleheads, episode 1

I was reading Debunking Atheists (probably my last time there) and saw Dan trying to rationalize the Noachian flood. For some unknown reason I erupted into a fit of mathematical dilettantism.

The Bible says that even the highest mountains were submerged and many people seem to agree that Mt. Everest is an acceptable measuring stick.

I got interested in how much water would actually be needed to submerge Mt. Everest. Several details such as the land mass above sea level, or the water from melting polar caps have been omitted in the following. This is as simple as it gets.

We will calculate the volume of the flood waters by calculating the volume of the Earth according to its mean radius (6731 km) and subtracting this value from the volume of a sphere whose radius equals the Earth's radius plus the height of Mr. Everest (6731 km + 8,848 km = 6379,848). The values have been rounded in this post, but were calculated to a greater accuracy.

Original volume of Earth: 1 083 206 916 845 km³

Volume with Mt. Everest covered in water: 1 087 726 237 887 km³

Volume difference: 4 519 321 042 km³

The volume of the Earth's oceans is approximately 1 300 000 000 km³ (source: wiki), hence the amount of water needed to achieve the end result of the flood is approx. 3,5 times that existing in the oceans today! Kewl!

Yes, this post is completely inconclusive, as per its inspiration.

Thank you for engaging this week's episode of 'BUNK'.
