The eye is indeed too complex to evolve via random mutation and natural selection. The irrationality award goes to those that believe that Darwin’s brain-dead natural selection god can assemple super-sophisticated biological nano-machines that merely give the “appearance” of design.
It is true that we do not know just how the first cells came into being.
But, given a reproducing cell, evolution hangs together better than any other theory.
Evolution is not about first beginnings. It is about the origin of species by natural selection. If you want to argue that a creator created the first cells a few billion years ago, fine. I will not argue with that possibility. If you want to say that a creator created the universe, with all the fossils intact and the physical evidence for an "old" earth and universe, 6000 years ago, fine. I don't want to destroy your faith.
