Scientism = a metaphysical claim about the scientific method being the only valid way to get knowledge about the universe.
I asked you for a specific example of something we could learn "about the universe" from a source other than the application of science. You refused to give one so we are no further forward.
One example of scientism is demanding scientific evidence to things beyond the scope of the scientific method
Yes that does sound like it would be a foolish thing to do. I haven't encountered anybody who does that. Do you mean like expecting science to tell us whether we ought to prefer pistachio or chocolate ice cream?
On the other hand when theists claim that god acts in the physical world - as you have - it is entirely reasonable to turn to science to investigate those claims. That would be a proper application of science.
