Efficient cause

Choose either the "Efficient Cause" or the "Design" argument for the existence of God presented by 'Aquinas'. Explain the Argument and how it is supposed to prove God's existence, using examples to demonstrate the principles/premises when needed. Then criticize the argument and point out where it might fail as a proof, using counter-examples.

choose only one argument, not both of them. you should fully explain the major premise in the argument and then be very complete in your criticism of it. i am not asking you to argue for or against God's existence but rather to critique a particular argument.
