Man created the calendars and clocks of the world. Letters can be converted into numerical equivalents, but that will be dealt with later. The system of numbers is divine in itself. Numbers are universal. The language of numbers is a universal standard of communication that can be understood by all.
Numbers are the entire basis of science and mathematics.
We may find and know of the divine by feeling it within ourselves, but this is intangible. There has been widespread conflict between Religion and Science from the earliest recorded history. Those who believe in God, or the Gods, have said that science is evil. Science, they told the people, was an unauthorized entry into the realm of deity. Have faith in God, they said.
