Go ahead, look at yourself, anywhere. What you see is more complex than you know, and more marvelous than you can imagine. Hands, for example, illustrate this.

Recently I watched a video put out by National Geographic in 1975 entitled, The Incredible Human Machine. In 50 minutes the program summarized some of the amazing systems of the body, throwing out facts that boggle the mind. The video started with Geographic’s usual evolution, speaking of chimps as our cousins and of 40,000 generations of people. But throughout, the writer inadvertently referred to design. “This part evolved in order to . . .” it said repeatedly. It’s as if evolution had a mind and will! How easy it was to see past the chance statements as the body systems declared throughout, “I am designed with purpose!”
Think about this one example. Our hands have 25 joints and can make 58 different motions. Our two hands contain over 25% of all the bones of the body and their muscles and joints are strong enough to support the weight of the entire body. The hand is so complex that a person wanting to perform hand surgery must have at least a year’s study beyond his MD. Each hand contains 29 major and minor bones, 29 major joints, at least 123 named ligaments, 34 muscles which move the fingers and thumb (17 in the palm of the hand, and 18 in the forearm), 48 named nerves (3 major nerves, 24 named sensory branches, 21 named muscular branches), 30 named arteries and nearly as many smaller named branches.
Consider just the thumb. The thumb is controlled by 9 individual muscles, which are controlled by all 3 major hand nerves. The thumb “moves in such a complex fashion that there are 6 separate descriptive terms just for particular directions of movement of one thumb joint.” What a marvel! No wonder Sir Isaac Newton said, “In the absence of any other proof, the thumb alone would convince me of God’s existence.” Thank God for your marvelous hands!
