They know that. It's just easier for them to mock than to think.
Sorry, but he's right. Ultimately, creationists *do* stop at "goddidit". Press them long enough for an explanation of why things are as they are (e.g., why endogenous retroviruses in DNA appear in various species in exactly the way that an evolutionary "family tree" would predict if they evolved from a common ancestor), and they'll resort to, "because God made it that way". Then they sit there happy and smug, despite the fact that they haven't bothered to address *why* God would choose to "make" DNA as if evolution had occurred, when there'd be no good (or even bad) reason to do so from a design standpoint.
"Goddidit" *is* where they stop thinking.
I'd like to show where the evos stopped thinking but one has to start to think before one can stop.
One of the ultimately stupid-est tenets of evolution is that everything happend through natural processes, yet so many exceptions have to be made to these natural processes that it becomes a series of miracles without God.
One incredibly cephalic evo stated that "if it happened, it was natural. Therefore everything happened naturally."
With thinkers like that you have no need for dummies.
