I don't think you understand.We don't really view superstition that way. I'm pretty sure that in the early days science was thought to be the superstition, not as we see it now as observable things we can verify, and we know do get verified, and we actually benefit from them in real life. For example, we get our antibiotics because we think that researchers have observed that they kill the germs in petri dishes. I don't think faith healing works supernaturally because I've never seen evidence for it. What we know is best a guess based on evidence, however, the science works consistently while the superstition never seems to hold up to scrutiny. I can light a fire, and because of science, I know what is happening.
Empiricism, due to the very nature it arrives at conclusions or draws from information, simply doesn't have the scope to lend authority to explicit causes. IOW, it relies on a sort of metonymic reasoning that never approaches the holistic, much like division by 2 of a number with value never arrives at zero.
IOW empiricism can never hope to invalidate the notion of god simply because whatever it claims to know is shrouded in mystery at either end of the macro/micro-cosm
