"It's as verifiable as the evolution of the TTSS into a flagellum."
On the one hand, you've got the rather mundane transformation of a small biological structure into a physically similar small biological structure with a different function. This is no more remarkable that a bird beak used for eatign bugs mutating into a bird beak capable of punching through bark to get at the bugs. Same structure, slightly changed through no will of the owner, into a structure capable of doing a new thing.
On the other hand, you've got an infinite God, capable of creating entire universes billions of lightyears wide, with every single subatomic particle specifically placed.
Now, for scientists, one of these propositions is far more extraordinary than the other, and consequently the level of evidence required for adequate confirmation would be equally extraordinary. But you equate the two as equally likely... which means to you a minor mutation is no more or less extraordinary than God.
As I said... interesting theology you have going there.
