A great many details we hardly think about are the products of engineering-designs and technology that have emerged after years of research, experience, and hard work by well-trained individuals.
For example, the refrigerator that keeps your food from spoiling was designed by engineers, as were your television, music set, elevator, watch, car and computer. All industrial machinery, satellites, spacecraft, and military technology are the products of engineering, representing the work and brainpower of a great many people.
Just like these designs that make our lives easier, there are countless designs in the bodies of living things that make their lives possible at all: perfectly functioning wings, cells that work like miniaturized chemical laboratories, infra-red-sensitive eyes that let their owners see in the dark, thick skin that can withstand heavy blows and harsh climactic conditions, and suckers that make it possible to walk on smooth surfaces- to name but a few.
When we compare such perfect designs in living things to the artificial designs that they often inspired, a striking parallel emerges: almost all the products of man's technology are no more than imitations of those in nature; and usually, they fail to match the superior design in living things, which are the work of Almighty God.
