If an intelligent designer designed humans, then why do we have:
crossover air and food pipes that make us very prone to choking
very vulnerable, relatively weak knee joints that are quite easily damaged
spines that are weak and very easily damaged simply by twisting the wrong way
a sharp ridge on the
inside of our skulls that causes severe brain trauma from not-that-hard of a blow to the head
a blind spot in our visual field
a propensity to develop hernias?
