The expression of the laws are constructs of the human mind, but I
guess you are OK that F=GmM/r^2 was as much approximately true
before human life appears on this planet and after. OK?
I think "approximately true" implicitly assumes someone for whom the
approximation is good enough. Someone with values and purpose.

There exists an as of yet unknown exact description of gravity. The
leading term of the expansion of that theory for large distances, low
energies and velocities will yield the Newtonian theory.
It's not much different from saying that sin(x) = x + O(x^3)
