Most cultures around the world independently arrive at a decimal system for counting things?
Why is this?
Because that’s the number of fingers on our hands. Childish and simple, but the truth. Look at a synonym for a number in our language: a ‘digit.’
Thus, can we say a decimal metric system is necessarily more ‘rational’ than a standard system largely based around numbers like 12 and 16?
Ancient Mesopotamian cultures based their numeral system around the number 60, evenly divisible by 12.
Computers are set up to do many things in hexadecimal, base 16, rather than the base 10 preferred by its ten-fingered users.
It makes best mathematical sense to use numbers most easily divided and factored as a base.
Thus a race of aliens with 13 fingers might also create computers that use base 16.
If we were to suppose the divine is reflected in the nature of the universe, Would humans in the image of the divine have had 12 or 16 fingers instead of 10?
