The most ancient distance measures were based upon the measurement of time, not solar transit time, but the time that it would take for the earth to wobble once as it spins and rotates around the sun. Before and after Noah’s Flood, the very slow wobble rate of the earth’s axis, its rate of precession, was known to be 72 years/degree (of 360), that’s 25,920 years for the earth’s axis to cycle once. Plato knew this number, having cited his “nuptial number” to have been half, 12,960 years, and so not surprisingly, the ancient greek olympic foot measure (of 12.16 modern inches), calculated long before Plato’s time, was based upon that wobble rate of the earth’s axis, 72 years/degree.
There are 6,000 olympic feet which compose the modern nautical mile, no coincidence surely, because the nautical mile is also based upon accurate timekeeping (arc seconds/minutes), so the modern foot length is not as was intended, to be a subdivision of the radius length of the earth, that radius length anciently calculated by simple hexagon geometry (meaning earth measure) according to the earth’s wobble rate, its very slow rate of precession, for when one side of a hexagon circumscribed by the circle of the earth is measured, the radius length of the earth is then known, thusly the ancients very accurately measured the size of the earth (see article #2 at http://iceagecivilizations.com).
The royal cubit of ancient Israel and Egypt was also earth commensurate (as explained in the link above), also calculated by accurately having measured time, and since the ancient hindu yugas of time are multiples of the reduction factor of the earth’s circumference manifested in the base perimeter length of the Great Pyramid of Giza, and as the babylonian sexagesimal number system, base six and 360 degrees to the circle, was clearly based on this archaic timekeeping method, it’s clear that the ancient world was accurately measured, even during the ice age (see Maps of the Ancient Sea Kings by Charles Hapgood) after Noah’s Flood.
