If you understood, you would know why that picture is not irrelevant.
To expand upon your argument: When only things that you can detect now with the five senses are real, and everything else is metaphysical, then all things of the distant past, like that lovely centaur, are equally "real."
I understand that you need to pretend that all things are 'equally real' and that your centaur picture is 'relevant'.
You merely want to disguise the basic metaphysical nature of evolution by pretending that people either believe that evolution is 'scientific' or believe in centaurs.
A foolish position, but ultimately where you must go to preserve 'evolution as science'.
