With all due respect, it would appear that you may be unaware of the vital role
mathematics plays in discovery of our physical universe.  There is a remarkably
insightful explanation in the Nova episode "The Great Math Mystery" aired March
30, 2016 on PBS:

    Is math invented by humans, or is it the language of the universe?
    Program Description:

    Revisit "The Great Math Mystery," fresh from the archives and just
    nominated for an Emmy Award.
    Join NOVA on a mathematical mystery tour?a provocative exploration of
    math's astonishing power across the centuries. We discover math's signature
    in the swirl of a nautilus shell, the whirlpool of a galaxy, and the spiral
    in the center of a sunflower. Math was essential to everything from the
    first wireless radio transmissions to the prediction and discovery of the
    Higgs boson and the successful landing of rovers on Mars. Astrophysicist
    and writer Mario Livio, along with a colorful cast of mathematicians,
    physicists, and engineers, follow math from Pythagoras to Einstein and
    beyond. It all leads to the ultimate riddle: Is math a human invention or
    the discovery of the language of the universe?

    "When scientists seek to understand the patterns of our world, they often
    turn to a powerful tool: mathematics. They quantify their observations and
    use mathematical techniques to examine them, hoping to discover the
    underlying causes of nature's rhythms and regularities.
    And it's worked, revealing the secrets behind the elliptical orbits of the
    planets to the electromagnetic waves that connect our cell phones.
    Mathematics has even guided the way, leading us right down to the
    sub-atomic building blocks of matter, which raises the question, ?Why does
    it work at all? Is there an inherent mathematical nature to reality? Or is
    mathematics all in our heads??
Religious practitioners have a vested interest in protecting their dogma; take
the Catholic church's behavior toward mathematician Galileo's 15th century
discovery of Jupiter's moons, and how mathematics revealed the Earth revolved
around the Sun, not the other way around, as the church had contended for
centuries.  The religious leaders nearly executed Galileo for publishing what
mathematics had revealed.  It took four hundred years for the church to finally
admit its error.

Likewise, "Intelligent Design" and creationism run country to the empirical
proofs grounded in mathematics.  I wonder how long it will take before they
admit their bias ...

Irrational acts are ultimately founded on irrational beliefs.
