But, would you make something perfect if imperfection could work well enough to accomplish whatever it is that you intended it to accomplish? Economically, it doesn't make sense.
I think it makes sense. I get the impression that everyone who wants to debate me doesn't want to give this idea the benefit of the doubt. I can see why people in the business world would want more perfection. Why should I keep debating these issues other than to learn about them? I could but I really don't have the time right now to debate the rest of you anyway. I would rather allocate it into learning and understanding the real issues such as understanding why eyes were designed (or evolved) the way they were, rather than taking the explanations of atheists (or even proponents of I.D.) as gold.
I can't prove this but it is possible the verted retina of the vertebrate eye does a much better job in protecting it from radiation damage. Since many of those invertebrates live underwater, salt water tends to filter out radiation at the surface.
I think you can pass judgment either way if your level of knowledge isn't up to the level needed to give the subject matter a fair judgment. It depends on how you wish to look at it either way based on whether you are an atheist or a theist. I believe this is rational but, it is a road many people don't wish to travel on.
