The only reason I am "hammering" on the human eye is that evolutionists point to our blind spot as "poor design" without an explanation of why our blind spot is "poor design".
I have read articles by experts in physiology and human vision in particular who have stated the blind spot in no way impedes our vision or is detrimental to humans and is in fact perfectly designed. Joe wants to use airline crashes as an example. However, I doubt Galileo was concerned with airplanes and neither were the billions of humans who lived prior to 1903. I can use boat and vehicle accidents to show that just being a human being in a powered vehicle is dangerous to our health so Joe is simply begging the question.
