Cantleave, your comments seem to imply that since living organisms have "apparent design flaws" they are not designed.
You then site the example of "the blood vessels positioned in front of the retina," stating that, "even a small hemorrhage can result in loss of sight."
If by this you mean to imply that the structure of the eye could not be designed, then I must point out that your logic fails.
This would be analogous to saying that since my radiator hose sprung a leak and my engine blew up, clearly none of it was designed.
Am I reading into your statements something you did not intend? If so, what is your purpose in pointing out the obvious fact that complex living organisms often have parts break?
