look at nature:  numbers, figures, mathematical rules ... - all are part of it

mathematical rules exist 'all the time' since there is more than nothing,
in other words: mathematical rules are involved in creating the universe,
or: emerging of a mathematical rule is equivalent to well-known Big Bang
nature is mathematical, one mathematical code rules our world
that code and mathematics in itself definitely are not inventions of humans -
we only have developed a complex language to describe simple preexisting laws!
we still are far away from seeing the simplicity in natural laws, but we know:
all really fundamental physical laws are pure mathematics
and it's impossible to comprehend laws of nature without playing the math game!
