Where there is design, there must be a designer. This is a fundamental axiom. Take for example the design of a pair of pliers – composed of only three parts (two levers with jaws and a pivot pin). The clamping action is simple, useful and evidences design. The modern automobile requires a much higher level of engineering in order to properly coordinate the many systems (braking, combustion, cooling, exhaust, electrical, etc.). When our cars do not function correctly, we might begin to cast blame on the designers for flaws, but we certainly do not question the existence of automotive engineers. Whether looking at the working of pliers (simple design) or an automobile (complex design), anyone can deduce that each had a designer.
Have you ever played with two magnets? When you get them close enough together they will usually snap quickly together. In a similar way the gravitational pull between the sun and our earth is trying to draw them together. However, the earth’s speedy elliptical orbit (approximately 66,000 miles per hour) creates a centrifugal force in the opposite direction. While on its circuit our earth has its own dedicated orbiter, the moon. It orbits the earth at about 2,200 miles per hour. The forces between the earth and the sun are perfectly balanced, as are the forces between the earth and moon. If any of these forces were altered, even slightly, these heavenly bodies would not remain in their dependable orbits.
Furthermore, this exact distance between earth and sun that results in orbital stability is also perfect to allow the sun’s heat to produce moderate, habitable climate on earth’s surface. What do we deduce from this display of perfectly balanced design? “For every house is builded by someone; but he that built all things is God” (Hebrews 3:4).
Remember our reference to the automobile? It evidences design by its interrelated systems. Now consider the human body. There are ten major systems of the human body (skin, skeletal, muscular, digestive, circulatory, nervous, respiratory, excretory, endocrine, and reproductive). These all function ingeniously in concert. “I will give thanks unto thee [God]; for I am fearfully and wonderfully made” (Psalm 139:14). See the fine book, The Human Body, Accident or Design? by Wayne Jackson (https://www.fortifyyourfaithbookstore.org).
The designs that abound all around us testify to the Great Designer. Read Romans 1:20 and Psalm 19.
