We didn't invent that mathematics of science, it was already in existence, we just discoverd those equations over time. The fact that they are true and real doesn't depend on any one persons belief or disbelief, just like the existence of God. Those equations demonstrate what I have said above, Einstein is a household name because of this fact.
I agree with much of what you said except for this part here. Equations are mathematical descriptions, by themselves they are, only descriptions and not prone to the accuracies of reality. We can derive formula for practically anything, but without real world observation the formula mean nothing.
You say the fact they are real and true does not require belief, this I can agree with, because evidence does not require belief. Seeing light bending around Jupiter's gravity well and supporting evidence for relativity requires no belief, -Merely that one understands the evidence presented. God however, requires belief. God is not quantifiable, god is not measurable, god is not describable in experiment nor formula.
