Modern miracles seem somewhat anemic. I would expect more from a God capable of creating universes. The following is a Scientific American article on how evolution explains our defects and diseases. Many people claim that God is all-perfect and he designed us. Our defects show that we are not perfect.
Evolution shows why certain defects, such as our blind spot, exist.
I am not aware of any religious model that explains the blind spot. Origins has a lot of information on evolution and the age of the earth.
