In my experiences, the common critic of Christianity, when he thinks of Christianity, imagines a sort of elementary, Sunday School blunder of elements: fiery Hell, an angry God, 'try not to sin', 'be good so that you can go to Heaven', absurd miracles, hyper-fundamentalist tales, religious hypocrites, and Jesus telling people not to judge. There is no horse more dead than such. I maintain that understanding Christianity and the Bible is quite like painting a piece of art. Let a toddler paint a puppy; then let an adult who is a long-time painter paint the very same puppy. They are both paintings of the puppy, but one is far more detailed, rational, realistic, and believable than the other. One is distorted and comical; the other is proportional and lively. One can write off Theology if he so pleases, but he might not be very wise in using the toddler's painting when it comes time to identify the real puppy or when trying to confront actual men of the Faith.
Dogs (like rats) are multitalented but they are also not very smart the way humans are. A recent book, devoted to the intelligence of dogs, is 250+ pages long (Stanley Coren, The Intelligence of Dogs: A Guide to the Thoughts, Emotions, and Inner Lives of Our Canine Companions, 1994). Interestingly, despite careful qualifications by Coren regarding definitions, the ranking of breeds by intelligence literally made newspaper headlines. We are obviously fascinated by the notion that dogs - or at least certain breeds of dog - might, just might, be really, really smart. It all makes as much sense as evaluating humans on our ability to sniff for bombs or echo-locate.
