YESSSSSSSSSSSSSS
Magic exists in D&D so it's not Supernatural. It's Natural. It's part of the world. How do Wizards use it? Science! They learn it from trial and error and doing various tests and making it work. Which is why Owlbears and other monsters exist because Wizard Experiments went awry!
Magic is totally normal and natural in a D&D Campaign Setting. Nothing supernatural about it!
... unless it -is- supernatural. Kind of a thing I plan to write into Sunset Riders. Magic, the arcane in particular, is -unnatural-. Not because it's supernatural compared to our baseline reality, but because it comes from another reality. From -beyond- the Prime Material Plane.
But on the plane it comes from? That's just how physics works, my dude. Y'know? THAT plane has really weird physics where wiggling your fingers and saying special words makes an explosion... And you're invoking those physics and placing them onto the Prime Material Plane, temporarily, because of reality-bleed between different existences.
Diving and Nature magic, though... those are natural.
