Like Mirdith said, this argument just isn’t trying.An eye is not a discrete organ. It needs an optic nerve. The optic nerve needs to connect to the brain. The brain needs to interpret the (name removed by moderator)ut. Evolution? I don’t think so.
I ask everyone reading this to think it through. Small incremental changes? That’s a lot of steps. Miss one, and it’s back to square one. A lot of steps to get from vague light receptor to fully formed eye.
However you also appear to have an extremly limited grasp of what evolution is. It might be better to actually know what you are talking about before you try to disprove it. I don’t suppose you’ve ever heard of cumulative selection? Yes, there are a lot of steps that go to make up the eye. The are organisms alive today that show some of these steps. They range from organisms with meer light sensitive patches to organisms with pits to contain the cells, to animals where the pits have closed over to form ‘pinhole cameras’ to animals where a lens exists. Now to jump from anyone of these steps to another in one leap would be ridiculously improbable. To go in many little steps over a large amount of time is clearly possible.
Your biggest mistake is to say ‘Miss one, and it’s back to square one.’ Why would that be? You think that if one organism was born with a slightly poorer eye then all the organisms of that species would automatically have the same eye? Or that when that happened some judge would come down and say, ‘no, no, thats all wrong, back to square one for you!’ Surely this one organism with a poorer eye does not mean that the whole specis is now going to deevolve to nothing?
Prehaps you will find that that organism has a worse eye and thus a worse chance of surviveing. Another organism of the same specis may have a better eye and a better chance of surviving. Through variation and natural selection, the best mutations are allowed to reproduce and become common, while the worse, at a selective disadvantage, dissapear from the population.
This is cumulative selection, very small incremental changes, but occuring with no direction. They don’t intend to make an eye. However, if in some small way they make a better one and that organism has a better survival chance, then unknowingly they will have.
