Since I finally gave up and put MM on ignore, I will cheerfully discuss this.
I used to be of the opinion that
scientism (that's the philosophy that science is the most authoritative and superior method for finding out what reality is like) was somewhat narrow-minded. A god-of-the-gaps "lite" school of thought, so to speak.
However, the argument for scientism is that science is so darn powerful when you apply it properly. For example, the benefits of various religions and philosophies could be studied statistically. Any deity or method that provides any kind of benefit should be revealed quite handily. The only remaining escape route is to postulate a deity that meddles in the scientific data to keep us fooled, which starts to sound like solipsism.
As far as current evidence goes, it seems any benefits of supernatural beliefs are equally supernatural (ie, good luck finding them in this universe). Add the rule of parsimony to this, and ignoring any such belief systems seems perfectly logical to me.
Certainly, science is never quite sure it has gotten things exactly right, but it's usually quite sure when something is wrong. Falsification works well for any philosophy that claims to have real-world effects.
