Why was Sexagesimal Counting Selected for Timekeeping the Base Six Method for Nautical Mile Mapping?

Befuddled by the fact that some of the ancients (such as the Sumerians) used the sexagesimal (base 60) numbering system which underpins our modern nautical mile mapping system, the biblephobes say it was selected anciently just because . . . . , no rational reason given, by ignorance of the seldom noted fact that the term geometry means earth measure, that achieved by the base six axial precession rate (72 years/degree) of the earth’s axis (see Page at right Great Pyramid for Navigation), the standard of timekeeping now the nuclear clock, yet the template the same base 60 because of geometry.
