1st calculate the volume required to cover the highest mountains. (Hint radius of the earth at sea level + 8.84 km).
umm which radius are you assuming?
this link states the radius 6.4 million meterWikipedianotes the following 3 radii
Mean radius 6,371.0 km
Equatorial radius 6,378.1 km
Polar radius 6,356.8 km
can't seem to find the +8.84 km you are referencing?
the highest mountain (Mt Everest) is about .07% of the earth diameter..or a difference in radius of about .035%....but lets be generous and increase your 8.84km radius into 8.85km (which would be a 0.07% increase of radius...otherwise the values start to get insignificant)
volume of 8.85km sphere equals 2903.5 cu. kmSteelHead wrote:2nd calculate the volume at sea level.

2903.5 cu. km - 2893.6 cu. km = 9.9 cu. km

your math is off, your logic is oversimplified, and your premise seems to be flawed.

it followed your reasoning out the window?
let us look at actual numbers.
- The volume of all the water on earth is approx 332.5 million cubic miles
- This much water just atop the United States would be 170 miles deep
- There is more freshwater "inside" the earth than "on" it (lakes, rivers, etc..)
- 70.8% of earth's surface is water, thus 29.2% is available for flooding....this assumes that 29.2% was available during Noah's flood, not more and not less..there is no way to determine either with any degree of accuracy.(20% of the land surface is already covered with snow/ice)
- 1,603,176,817,000,000 sq ft of land surface
- the highest point on land is Mt Everest at +29k feet
- 48,095,304,510,000,000,000 cu.ft of water...or 326,738,952 million cubic miles
So, we see that there is enough water currently available on earth to flood the entire available land surface to over the top of the highest point of land (Everest). However, this only leaves 5.8 million cubic miles of water to "fill in" where there was no previous available land surface....which was a water surface area of 3,887,192,497,000,000 sq feet or 139,433,845 sq miles...or about 221 feet of water depth for that surface area.
Now realize that with regards to the earth, it is not a sphere...it is an oblate spheroid, but our calculations can illustrate the point. Furthermore one must realize that the radius of the earth is only increased by .035 percent (.0007) if we take Everest as its outer radius, as compared to taking sea level. Besides i am not sure that all the assumptions being made are valid...for example, if the entire subsurface water evacuates to above surely there will some significant collapsing of land surfaces, a sinking effect for some land masses...probably not significant to mountains but perhaps meaningful.
Now, obviously there is enough water to actually cover the entire earth, albeit asymmetrically applied (as it is applied today)...but there may be cause to consider this as feasible considering that water may well ebb and flow, swell and squall to being less than an evenly distributed elevation over great expanses...especially since it already does that significantly across our earth today (ie. tidal bulge due to moon).
See a graphic model of this asymmetric distribution at the bottom of this pagethat image represents the major flaw in your assumption above, which is that the water would have to be a consistent depth across the subsurface of the planet....and this influence is just from a solar/lunar source.
The assumption that the flood would have to be to the depth of Mt Everest consistently across the entire earth is rather naïve, unnecessary, and just not rational. The scientific data supports that our planet is actually asymmetric in shape and thus the surface of the sea at any given point is not actually equidistant from the earth's center....and arguably since a large portion of Everest is under ice already, complete coverage may not be necessary for one to consider it "flooded" for the purposes of extinguishing life....but i still maintain that the earth is capable of being "waterworld" and current science and the tradition of religion support that conclusion. The only objections are fro those who want to simply assume that the flood is some sort of linchpin in the fall of the Bible, wherein their only argument is that "it just seems to not be possible", yet we see that science is revealing more and more that indeed it is possible.
