How about civilizations which developed using Base 20?
http://en.wikipedia.org/wiki/AbacusSome sources mention the use of an abacus called a nepohualtzintzin in ancient Mayan culture. This Mesoamerican abacus used a 5-digit base-20 system.[22] The word Nepohualtzintzin comes from the Nahuatl and it is formed by the roots; Ne - personal -; pohual or pohualli - the account -; and tzintzin - small similar elements. And its complete meaning is taken as: counting with small similar elements by somebody.
Do they not know god? Is this the real reason why missionaries were sent to Africa and to Central America?
It has been pointed out already that we most likely use Base 10 because of the utility of counting the fingers on both hands - some societies developed only counting on one hand at a time, generating a Base 5 system; others counted fingers and toes, leading to Base 20.
Of course, all your assertions that god is demonstrated via Base 10 are ludicrous in the extreme when you look at the history of one of the longer-running successful math systems; the one which gives us 60 seconds per minute, 60 minutes per hour, and 360 degrees in a circle.
http://en.wikipedia.org/wiki/SexagesimalSexagesimal (base 60) is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, it was passed down to the ancient Babylonians, and it is still used — in a modified form — for measuring time, angles, and the geographic coordinates that are angles.
