The point isn’t that we know all the causes now, it’s that Occam’s Razor demands we look first in reality for those causes before positing that there is a magic being which is non-resident in space/time that sets up these laws or influences things directly.
We have two options: create and test various hypotheses for causes of gravity, or assume that a magic invisible being did it somehow.
So?
Math is a language with its own syntax and grammar. It’s a language which we created.
Because it’s the best system we have, flaws and all.
Wish in one hand, spit in the other.
See which fills up first.
Eh? I don’t believe in a God, and yet my laptop is working right this minute. Many people don’t believe in God, and their technology has not suddenly stopped working. If you make a claim, the burden of proof is on you. The null hypothesis is that there are no magic invisible monsters which make my computer work. If you suggest otherwise, you have to prove it.
I’d also enter into evidence that our ancestors discovered the technology of making fire long before Yoshua Ben Yoseph walked the earth. I’d point out that the Romans had advanced engineering and the Greeks had advanced science too. I’d point out that the Egyptians developed papyrus without a helping hand from Christian or any other monotheistic faith. So it certainly does seem that non-belief in your God doesn’t shut down technology.
You’re conflating two issues.
Science can tell us how to grow enough food to feed our population. Various social/economic/political theories can tell us what to do with the food once we grow it. But religion, no matter how fervent, will never sprout a seed or harvest wheat. Moreoever, virtues like compassion are not the sole domain of religion.
Also, religion certainly doesn’t always do a great job of when it comes to justice. The Crusades spring to mind. The Inquisition springs to mind.
Science cannot tell us the ‘why’ of a thing, that’s left to philosophy. But science can tell us the ‘how’ of a thing. Science is responsible for everything from velcro to clock radios to atom bombs. You can pray till you turn blue in the face, but you won’t create any atomic weapons out of thin air.
