ID proponents will tell you that the eye cannot have been produced naturally. Eyes were in existence before the fall. Would you like to explain that?
Is this going to be a bad eye design argument?
Animals and birds had eyes before man was created and the fall.
The creation account also tells us God created a good world.
299 Because God creates through wisdom, his creation is ordered: "You have arranged all things by measure and number and weight."151 The universe, created in and by the eternal Word, the “image of the invisible God”, is destined for and addressed to man, himself created in the “image of God” and called to a personal relationship with God.152 Our human understanding, which shares in the light of the divine intellect, can understand what God tells us by means of his creation, though not without great effort and only in a spirit of humility and respect before the Creator and his work.153 Because creation comes forth from God’s goodness, it shares in that goodness - "And God saw that it was good. . . very good"154- for God willed creation as a gift addressed to man, an inheritance destined for and entrusted to him. On many occasions the Church has had to defend the goodness of creation, including that of the physical world.155
Providence and secondary causes
306 God is the sovereign master of his plan. But to carry it out he also makes use of his creatures’ co-operation. This use is not a sign of weakness, but rather a token of almighty God’s greatness and goodness. For God grants his creatures not only their existence, but also the dignity of acting on their own, of being causes and principles for each other, and thus of co-operating in the accomplishment of his plan.
307 To human beings God even gives the power of freely sharing in his providence by entrusting them with the responsibility of “subduing” the earth and having dominion over it.168 God thus enables men to be intelligent and free causes in order to complete the work of creation, to perfect its harmony for their own good and that of their neighbors. Though often unconscious collaborators with God’s will, they can also enter deliberately into the divine plan by their actions, their prayers and their sufferings.169 They then fully become “God’s fellow workers” and co-workers for his kingdom.170
308 The truth that God is at work in all the actions of his creatures is inseparable from faith in God the Creator. God is the first cause who operates in and through secondary causes: "For God is at work in you, both to will and to work for his good pleasure."171 Far from diminishing the creature’s dignity, this truth enhances it. Drawn from nothingness by God’s power, wisdom and goodness, it can do nothing if it is cut off from its origin, for "without a Creator the creature vanishes."172 Still less can a creature attain its ultimate end without the help of God’s grace.173
