If you, a mere human being, cannot fathom how this could be done then you must assume creationism to be true.
Or you could go to school and learn something about physiology and anatomy.
I guess you know the facts, fill us in.
Did your college class create an eye in a Petri dish? Maybe you are just making a few assumptions that they forgot to teach you.:-)< /sarcasm >
But seriously, as we discover how complex the inner workings of the cell are, we need to pause and determine if a 150-year-old process needs a serious checkup. Pulling teeth in the science community doesn't come easy.
When the nerve of the community finally dies, we might see more scientists choosing to get an evolutionary "root canal".
Since you are so smart, suppose you tell us how the human eye with its numerous parts evolved gradually. Kindly include all the parts necessary for it to have proper functioning and also kindly do not use the words 'imagine', 'possibly', 'perhaps', 'maybe' or 'could be' which are not scientific terms.
