Just another form of argument from incredulity. "I don't understand how the eye / the human body / life / the universe could exist without a creator, therefore, god. And by the way ... I don't want to understand, either. My ignorance is what feeds my faith."

Creationism, the first choice of the stupid and the lazy.

The evolution of the eye is really not as remarkable as those who'd like to claim it must be the result of intelligent design like to claim.

Plants, as we all know, are able to detect light and direct their leaves towards it, thus maximising the amount of food they can produce for themselves through photosynthesis. Likewise, many very basic animals have eyespots, organs capable of distinguishing between light and dark, in order to regulate circadian rhythms. Whilst eyespots are not capable of discerning detail or movement an organism which, thanks to a chance mutation, is able to react to a very sudden switch from light to dark by getting the hell out of the way because such a change is likely to mean another animal, perhaps a predator, is overhead has a very obvious evolutionary advantage and will have a greater chance of passing on its genes. One of its offspring then has the chance mutation that allows its eyespots to detect green light - and thus it can detect the presence of the phytoplankton upon which its species feeds and, when it detects it, beat its flagella in pursuit rather than waiting around for chance encounters - so it passes on its genes too. This process, survival of the fittest, continues over many generations to the present day - and suddenly, the evolution of the eye doesn't seem quite so extraordinary.
