Looking at a building, I don't need to be able to touch/smell/see an architect to know that there was one. My eyeball is infinitely more complex, and Darwin himself admitted that the formation of the eye through natural selection seemed highly absurd. (Something like "If you didn't have photosensitive cells, how would you know about light? If you didn't know about light, why would you develop photosensitive cells?")

Anyhow, middle school mathematics teaches that if the probability of one thing occuring is slim, then the probability of it *not* happening is high. And the chance that the functions of the human body just came together and *happened* is, as George Gallup so nicely said, a statistical monstrosity. So probability-wise, a Creator has a fairly good chance of existing.
