Since very early times humans have counted in tens – presumably because it was easier to count by using fingers and thumbs for visual assistance.
Scientists have noted that many megalithic structures are built in, or hieroglyphs describe, multiples of twelve or sixty. It’s easier to set out a circle of stones with twelve items as number twelve at the top and six at the bottom and three and nine are opposite, whereas with ten, the position of 10 at the top requires half between 5 and 6 at the bottom which is difficult to set out Setting out a stone circle with positions at north, south, east and west is easier with a duodecimal system.
Calculating fractions for division of assets results in more whole numbers with the duodecimal system, for instance dividing amongst two, three, four or six children results in whole numbers whereas with the decimal system only division by two and five is a whole number.
It has been proposed that we should have a counting system based on twelve, ie single characters for 1,2,3,4,5,6,7,8,9, plus a first new character, plus a second new character, then digits 10 where the new 10 represents our current 12. All mathematics, theorems and equations would have to be recalculated but it might produce some interesting results! It’s unlikely to happen especially as the digital system uses a binary system of just two characters, on or off, positive or negative, visible or invisible, black or white.
