Well, what counts as an eye? When in development does an eye become an eye? If it isn't complete, is it still an eye? In order to be considered complete, shouldn't it be able to see? Seems like the eye and sight are two sides of the same coin.

But then again, some people have eyes that can't see. Sight is both the defining feature of an eye, and also not necessary to define an eye. Maybe our languages aren't specific enough. Let's say the capital E Eye is a concept of an organ defined by the fact that it sees, (like how some frogs have rudimentary third eyes on the tops of their heads which just sense light above them) while a lowercase e "eye" is any object which resembles an organ that sees. Then the Eye works in the previous paragraph.

Good point, how could sight come before eyes? Maybe I'm missing something

Kind of at the same time. The form of the eye as it exists now is one that has been iterated on, but without the benefit of an eye-like organ it would not have been selected for.

Depends on what you mean. Obviously plants and photosensitive tissues have been sensing light for a long time, millions of years. But hose aren't eyes, and most wouldn't even call that poor sight.

A baby human usually has its eyes closed at birth, and the brain isn't completely formed until 25 years old. It takes at least a few years after birth for all the basic parts to settle in and get developed. So does a baby have sight if it hasn't yet used it's immature eyes? Does it truly process what it "sees" into anything meaningful in the beginning?

If there is a spirit that exists before life, does it "see" and with what?
