This will mean nothing to Bible Thumpers. They live in a self-created alternate universe of steadfast denial. There is nothing that can penetrate their psyches, especially science, which is the spawn of Satan.
I think their argument will go something like this: “God is testing our faith in him and in his divine word, as revealed in the King James Bible (and only the KJB heathens!) by tempting us with scientific evidence that is contrary to His holy word.”
I remember the furious tap-dancing they did when Carbon 14 dating proved that the Shroud of Turin is a Medieval fake, circa 14th century. Oh, pay no attention to the man behind the curtain! The great OZ has spoken!
