Eventually and overall it is best to approach what we do not understand from the perspective of intelligent design. That's how science and medicine work best. I would wager Darwinism and/or materialistic naturalism take little if any credit in dispersing misnomers attributed to the miasma theory of disease.
Another bizarre utterance from FesterWorld.
"God did it. Okay, we can pack up and go home now, nothing to learn here."
I've heard of theories using the god of the gaps to fill in the holes, but you want to replace an entire theory with one big gap.
