Now of course, it is somewhat like shooting fish in the proverbial barrel. Past scholars, uncharitable toward literalist believers in "biblical inerrancy," have calculated the needed size of the Ark, for example. Were even just all known mammal species shoved aboard, shoulder to shoulder -- you'd need a hundred modern aircraft carriers.
In fact, this argument has had results! Creationist "scientist" Ken Ham conceded -- in his recent debate with Bill Nye -- that evolution (yes "evolution"!) must have radiated all the species we now see, from a seed population that rode upon the Ark! I cannot believe this major concession got so little play in the media or among devotees of either religion or science. It is a real shift in ground.
