While I'm not an expert in eye physiology, I hope I can point you in the right direction. To answer your first set of questions, God did design everything the way He wanted, "in the beginning". There's a huge difference between the Intelligent Design movement and Biblical Creationism. IDers do not address *who* the designer is. Could be God, Allah, Buddha, Homer Simpson, etc. Biblical Creationists have a worldview founded in the Holy Bible, which makes their worldview cohesive. Because of Man's rejection of God in the Garden of Eden, the original creation became corrupted. This introduced death, both physical and spiritual. So Adam did die in noth senses of the word: he died immediately (spiritually) and began the process of dying physically (as we do once we reach physical maturity). As for the design of the eye, I would direct you to Answers_in_Genesishttp://www.answersingenesis.org/ . This site has answers to many questions from a Biblical Creationist point-of-view, written by PhDs in many fields including biology, chemistry, physics, astronomy, etc. For the record, I have a PhD from NC State University in molecular biology, and I am a Biblical Creationist. Evolution does not adequately explain our origins, and is itself *not* science. It's a naturalist/humanist religious belief. No one has ever observed organisms changing from one kind to another (ie. canines always have canines, felines always have felines, etc.). Since no one can recreate the past, and none of us physically observed the creation of everything, it is an untestable hypothesis. This is why we should teach evolution AND creation, warts and all. This way students can make up their own mind as to what to believe. Hope this helped!
