Whether or not math is a property of the universe or a construct of minds is a maddeningly philosophical debate.
Seems pretty clear cut to me... for us to "invent" something so exact is absurd. We only create the system of which we understand maths... ie decimal, binary, etc.

The concept one 1, 2, etc... the earth and the moon make two... there are two things there... whatever word or symbol you wish to use for two, however you interpret two, there will never be someone who sees three things there unless to them three is the word they use for two.

Maths is the language of nature.
