It is said that the mechanisms of evolution (natural selection, sexual selection, etc.) only enhance or diminish traits (populations with long necks get longer necks, populations with little arms get smaller arms).
If the mechanisms of evolution only enhance or diminish traits and not create, then to explain eyes that would mean that there would have to have been a creature with some kind of proto eye already in existence to enhance, but it seems unlikely that just a mutation would by chance produce an eye. How do you reconcile the existence of the eye and the fact that the mechanisms of evolution only enhance or diminish traits?
