How many metres in a cubit? The answer may astound you.

Dear Readers,
I know it's only been a day since I edited my last post (if you haven't read it yet, I highly advise it), but I just have to share what I learned today about the Egyptian cubit. If you watch the relevant minute of the referenced video, you will see that the most ancient Egyptian cubit is a function of the ratio of pi and phi in metres, out to four or five digits (.52356) over the precise 230,366½-millimetre width of each of the Great Pyramid's four sides.
This would indicate that the most ancient Egyptians were aware of the relationship of geometry to base ten out to five digits--a metre is the distance from the equator to the pole, divided by ten thousand--as well as the irrational numbers of higher mathematics. As later generations of Egyptians lost this knowledge, it stands to reason that their cubits became less and less precise--ranging as much as a centimetre off the ancient standard (and even more so by the time we get to the TNIV).
If the Egyptians at the dawn of history were capable of manipulating such abstract numbers to such precision, it lends credence to the idea that the numbers in Genesis chapter five--even more ancient--are the result of equally complex calculations. Note that in each of the nine generations enumerated, the age at which the son was begotten always ends in zero, two, five, or seven--as do the lifespans of the first seven generations. This is regardless of whether one follows the Hebrew, Greek, or Samaritan numbers. And as it turns out, two and five are among the factors of phi squared; it appears that some complicated mathematical formula was at work in producing ages that always ended in one of these two factors of phi squared, or the sum of them. And it appears that we are only now finally coming to the point in our understanding of ancient mathematics to be able to transcribe these numbers into something more useful to our purposes, which is establishing the time span between Creation and the Flood.

This video shows a tablet from ancient Babylon now understood to contain formulas of higher mathematics used to construct triangles from an entirely different perspective than has been used for the past 2500 years. Clearly Ancient Man was much more intelligent than materialist paradigm has been willing to accept. Perhaps more on that, in a later post.
