but I don't believe that humidity in the pyramid is definite proof that it was built in an antedeluvian eraYou must.
The study was conducted by Stanford University.
"Limestone from all over Egypt was tested against Cheops limestone for water content.
The results were that Great Pyramid limestone is UNIQUE because it is saturated with MOISTURE and not found anywhere else in the world.
It is antediluvian limestone."

Stanford University
During its autumn 1974 electromagnetic sounder experiments the joint Egyptian-American research team established that high attenuation
due to high water content in the limestone of the Giza area precluded many practical applications of radio-frequency sounding for archaeological purposes in that area.
Did the antediluvian builders use meters? Seems fairly unlikely, since that was a French invention.They sure did.
The angle that each face of the Pyramid makes with the base is exactly 51.8554°.
90° - 51.8554° = 38.1446°
All of the inner and outer measurements of the Gizeh pyramid were determined using three circles each having a radius of 60 sacred cubits = 38.18 meters (one sacred cubit = 0.636363 meters).

The value of 38.18 can only be inferred if, and only if, the 60 sacred cubits are expressed in meters.
51.85/38.1 = 1.361
5.23 (masonry base) + 136.1 (pyramid frustum w/o the masonry base) + 7.28 (apex) = 148.61
Is it reasonable to convert degrees into meters? No, never.The same figure, 38.18, comes up again and again. Explain how the ancient Egyptians knew that the angle had to equal 38.15 degrees.
Does one sacred cubit = 0.636363 meters? You haven't done your homework.
The sacred cubit is designated in the form of a horseshoe projection, known as the "Boss" on the face of the Granite Leaf in the Ante-Chamber of the Pyramid. By application of this unit of measurement it was discovered to be subdivided into 25 equal parts known now as: Pyramid inches.
I can't do your writing style justice, but I'll do my best.That is not parody, but trying your best to deflect and dodge the issue being discussed here.
In order to find the values of the two angles, 51.8554° and 38.1446°, the architects had to solve these equations:
TAN X = 1.27330478216 = 0.636652 x 2
SIN X = 0.617648
To find the final value of 51.8554 degrees, the architects MUST have used the extended arctangent series to achieve the final result.
Just a "very good approximation" won't do it.
One needs the correct value to the fifth decimal, something that can be achieved ONLY by using advanced calculus.
There is no way that Euler's extended arctangent series would have been used 4,500 years ago by the civilization which built the Gizeh pyramid: the entire development of the accepted chronology of history would be defied on a monumental scale.
The architects of the pyramid did use the extended arctangent series exactly in the 17th century, when they also infused the knowledge about calculus into mainstream science in Kerala, France, Italy, and England.
In case you haven't noticed, 2.3 million blocks of stone were used to build an edifice which is precisely based on these angles: 51.8554 and 38.1554 degrees.
These angles, in turn, were derived using the fundamental distance of 60 sacred cubits.
But 60 sacred cubits = 38.15 meters.
This is what you are desperately trying to dodge.
