I think what could possibly lie at the heart of this mystery is the number 432,000. If you add up the ages of the Babylonian kings who ruled before the flood, you get 432,000. So given that this number crops up in several civ's mythologies, these kings' ages could just be part of a cosmological metaphor.
For instance, it was the favourite number of the Vedics: 432,000 or multiples of it, makes up the number of years of a Vedic yuga (or age). Thus the current yuga (Kaliyuga) lasts for 432,000 years, the previous one lasted for 432,000 x 2 = 846,000, the one before that was 3 x 432,000 = 1,296,000, and the first one, Kritha Yuga, lasted for 4 x 432,000 = 1,728,000. These all added together make the Great Yuga of 4,320,000.
In the Norse mythology, there is a great battle of the gods that marks the final days (Ragnorak in Norse, Pralaya in Vedic), and the “Einherier” (warriors) all issue forth from the gates of Valhalla. As recorded in the Grimmismal:
“Five hundred gates and forty more – are in the mighty building of Wallhala – eight hundred Einherier come out of each gate – on the time they go out on defence against the Wolf.” Anyway, as I’m sure you’ve noticed, 540 x 800 = 432,000.
The temple at Angkor Wat in Cambodia is built using sacred geometry which is based on the number 432,000:

In addition, the Greek mathematician Ptolemy used 432,000 as the totality of the "Great Circle" of musical frequencies.Speaking just of numbers, the various lengths and circumferences of units representing the motion of the moon may equal 27, 28, 29 (nakshatras or days of the month), 354 (days of the lunar year), or 360 (tithis of the lunar year).
Other lengths represent the solar year (360, 365, or 366) or larger time cycles.For example, the west-east axis represents the periods of the yugas. The width of the moat is 439.78 cubit; the distance from the first step of the western entrance gateway to balustrade wall at the end of causeway is 867.03 cubit; the distance from the first step of the western entrance gateway to the first step of the central tower is 1,296.07 cubit; and the distance from the first step of bridge to the geographic center of the temple is 1,734.41 cubit.
These correspond to the periods of 432,000; 864,000; 1,296,000; 1,728,000 years for the Kali, Dvapara, Treta, and Krita yuga, respectively.
And the Rig Veda has, according to certain sources, 432,000 syllables....
I think if we can solve the riddle of 432,000, Monk, we will have the answer to your question. There is a view that the number is cosmological, and may even be related to our old friend, the precession of the equinoxes!

The Chatur-yuga [the Great Yuga, or all four yugas added together], 4,320,000 years is related to the precessional cycle, 25,867 years corresponding to a precession of 50.1 arc-seconds per year. This is amazingly close to the normally accepted value of 50.2 arc-seconds for the precessional constant.
