You say that it’s not impossible for our ear to have developed through mutation and natural selection. You say that there’s no evidence. You challenge me to find a paper that addresses this issue. I admit that I can neither think of a paper that answers your question nor come up with an experiment on my own. The discussion is ripe for a coup de grace - your contribution to science through the publication of the first peer-reviewed paper that supports creationism without resorting to supernatural explanations. You’ve already won your challenge. If you publish that paper, you can win the war.
Based on how entrenched your beliefs are that creationism has a rightful role in the public science classroom, a thousand scientists could laugh at you in an auditorium and you’d still be the same old preternaturally intelligent Russ Paielli.
But who cares about these thousand un-“enlightened” scientists? Your successful publication will result in an automatic senior fellowship at the Discovery Institute. It’s win-win for you as you get in the history books and a comfortable salary. Heck, you might even get a Nobel Prize.
Do it. Challenge science. Enlighten the unenlightened.
