Some people look at the existence of life on earth and -- notwithstanding the obvious fact of our existence -- they assume that it's impossible. Therefore, starting with that assumption, it's entirely logical for them to conclude that something miraculous must have happened to make the impossible happen. But it all hinges on the "impossibility assumption." I suggest that this creationist assumption is employed only because it forces the desired conclusion. And when you've become attached to the conclusion, it's quite natural to hold onto the initial assumption.
They realized they couldn't enter any contestants into the annual Darwin Awards if they banned Darwin, I guess.
