“where it originally came from: down below.”
If the earth is treated as a sphere an approximate estimation for radius is about 6700 km. Assuming the water from this flood was 2.5 km high averaged across the earth a rough estimate for the volume of water is
4/3pi(r^3)
4/3pi(6702.5^3 - 6700^3) = 1,400,000,000 cubic km of water.
If all that water were placed into a giant sphere the diameter would be greater than half that of the planet pluto.
Again you never answered any of the questions except taking a small quote out and then saying rediculous statements. Why would looters remove fish bones and algae rather than gold and treasure? Why would the pyramids not be under water long enough for marine life to live there, yet the grand canyon (which you claim to be evidence of the flood, is 2000 m in altitude above cairo egypt) does have fossils.
You are a true head case!
You imagine up all sorts of ridiculous scenarios, and expect others to join your bananna head game.
Max depth of water for the flood: 2000 feet, but probably less, and it all came from “the fountains of the great deep.” Some had to go back there as the plates shifted and buckled.
You’re not much of an estimator.
If you want your foolish questions answered, use the search engine; that’s what its for.
