So the interesting question is: Did Jehovah God himself choose the decimal numeral system? (His son will reign for a thousand years etc.) Or did he adapt himself to a system that humans invented?
Without a television at home ( to protect us children from bad influences), I read all the old Awake magazines. And yes, it was helpful eventually - to wake me up.

Different Numeral Systems
The decimal system is called a base-ten numeral system. But any other numeral base can be used. Babylonians used a complex base-sixty system and the Mayas of Yucatán calculated in base twenty. Today computers use the base-two system. “New math” courses familiarize young children with different numeral systems. The purpose of this is to help them gain a better understanding of the familiar decimal system, and of arithmetic in general.
The base-five system is perhaps the easiest one to learn, and it may be taught to your fourth or fifth grader. In this system, which uses only the numerals 0, 1, 2, 3, 4, each position has a value five times greater than the position to the right. Thus in the number 324, the first numeral represents itself, or 4. The second numeral, instead of representing 2 tens as in the decimal system, represents 2 fives. And the third numeral, instead of representing 3 hundreds, represents 3 twenty-fives. So 324 in the base-five numeral system is really 89 in the base-ten system!
This same pattern is followed in every numeral system. Thus in the base-six system each position has a value six times greater than the position to the right. And in the base-eight system each position has a value eight times greater than the position to the right. Note the value of the number 324 in the numeral systems below as compared with its value in the decimal system.
324 in base five = 75 + 10 + 4 or 89
324 in base six = 108 + 12 + 4 or 124
324 in base eight = 192 + 16 + 4 or 212
