GTP-transducin-activated rhodopsin now binds to a protein called phosphodiesterase, located in the
               cell's inner membrane.  When attached to activated rhodopsin and its entourage, the
               phosphodiesterase acquires the ability to chemically cut a molecule called cGMP (a chemical relative of
               both GDP and GTP).  Initially, there are a lot of cGMP molecules in the cell, but the phosphodiesterase
               lowers its concentration like a pulled plug lowers the water level in a bathtub.

                                              Another membrane protein that binds cGMP is called an ion channel.
                                              It acts as a gateway that regulates the number of sodium ions in the
                                              cell.  Normally, the ion channel allows sodium ions to flow into the cell
                                              while a separate protein actively pumps them out again.  The dual
                                              action of the ion channel and pump keeps the level of sodium ions in
                                              the cell within a narrow range.  When the amount of cGMP is reduced
                                              because of cleavage by the phosphodiesterase, the ion channel closes,
                                              causing the cellular concentration of positively charged sodium ions to
                                              be reduced.  This causes an imbalance of charge across the cell
                                              membrane, which causes a current to be transmitted down the optic
                                                                               clix
               nerve to the brain.  The result, when interpreted by the brain, is vision.

               Let's ask ourselves a couple of questions:
               1.  Is this an extraordinary and complex organ in our body?  YES!   Is it improbable that something this
               complex could have happened by chance?  YES!  ABSOLUTELY!

               2.  Does the complexity of this organ match specific patterns in other areas of science?  (Sodium pumps,
               chains of complex enzymes activating or deactivating other chemicals, etc.)  YES!

                                 We can conclude, as we did with Mt. Rushmore, that the eye was created by a
                                 designer of tremendous intelligence.

                                 Dr. George Marshall, an eye-disease researcher from the University of Glasgow,
                                 Scotland, said when asked, "How do you react to the notion that the human eye is
                                 the product of evolution?  (chance)"

                                 The more I study the human eye, the harder it is to believe that it evolved.  Most
                                 people see the miracle of sight.  I see a miracle of complexity when viewing things at
                                 100,000 times magnification.  It is the perfection of this complexity that causes me to

               How do we detect creative design?
               Imagine a room in which a body lies crushed, flat as a pancake.  A dozen detectives
               crawl around, examining the floor with magnifying glasses for any clue to the
