It is also important to point out that the design of the eye does not appear on close inspection to be completely ideal. The rods and cones that sense light are the bottom layer of the retina, and light has to pass through the nerves and blood vessels to reach them. Similar imperfections of the human spine (not optimally designed for vertical support), wisdom teeth, and the curious persistence of the human appendix also seem to many anatomists to defy the existence of truly intelligent planning of the human form.
Theism knows this word is painful; it should not be expecting perfection anywhere short of God/heaven. In fact to see perfection anywhere else is a form of idol worship.
