And I still think that the agnostic argument from similarities between Christianity and paganism works only if you know the answer. If you start by knowing on other grounds that Christianity is false, then the pagan stories may be another nail in its coffin: just as if you started by knowing that there were no crocodiles then the various stories about dragons might be helpful to confirm your disbelief. But if the truth or falsehood of Christianity is the very question you are discussing, then the argument from anthropology is surely a petitio.
