Turns out, the cause of disease can be seen under a microscope. We found a way to observe the previously unobservable. Awesome.
But when physicists start talking about "something from nothing", they have jettisoned scientific inquiry. At least you can try to observe evil spirits and deamons (which is how the real cause of disease was discovered). After all, that's all science is: observing, and applying those observations. But you can't observe nothing. Ergo, you are in the wrong sandbox, kiddo.
