The study on birds' feathers, wings, pupils of the eyes, skeletal frames, respiratory organs, digestive organs, heart and circulating system tells us that those organs of birds are like the most excellent machines designed with the best high-leveled aerophysics and their art and efficiency of flying is better than any other aircrafts. And through the study on the velocity, center of gravity and economical efficiency of a ship, shipbuilders and naval architects concluded that they should make the proportion between the length and width of a ship the same to that of a fish. These facts teach us that everything was designed and created by the Creator. "So God created the great creatures of the sea and every living and moving thing with which the water teems, according to their kinds, and every winged bird according to its kind. And God saw that it was good." (Genesis 1:21) From Rev. Dr. Jaerock Lee's Serial Column "Siloam" on Dong-A Ilbo
