Chance or Design? Amazing Feats inside the Human Body

Amazing Feats inside the Human Body

I never stop being amazed at the complexity, intricacy and engineering marvel of the human body. The human body contains upwards of 10 trillion cells. Each cell, too small for the naked eye to see (0.001 cm3), works as a chemical factory performing thousands of functions, often in a fraction of a second, coordinating each function with thousands of neighboring cells. Each cell can replicate itself within 24 hours. The cell controls hundreds of millions of biochemical and biomechanical events per life cycle. When replacing its DNA, the tiny bacterium E. Coli, copies 1000 nucleotides per second with very few mistakes. Compare this to the robots we have sent to Mars, which are called ‘marvels of human design’. They are about the size of a small car (a billion times larger than a cell), able to do many hundreds of functions, but unable to replicate themselves. Yet atheistic evolutionists consider the cell a result of undirected, random processes.

The information content of these trillion cells operating as a ‘well oiled machine’ is more than all accumulated knowledge  of mankind (estimated to contain bits of information with ten raised to the  two millionth power). Our brain, the organ that processes information, controls the body functions and is the seat of our consciousness is made up of 80-120 billion neurons. Each neuron made up of 100,000 molecules, and each neuron has thousands of connections to  its neighbor neurons (called axons and synapses).

Another critical organ, the human heart, pumps 22 liters (6 quarts) of blood through 96,000 miles of arteries and capillaries, beats 100,000 times in 24 hrs and continues to do so for an average lifespan of 80 years, without repair. Which man-made pump can match such a feat? And yet, some consider this unique organ to be the result of unguided, random processes developed over eons of time.

These are just a few examples of the wonders in God’s world exhibited in our own bodies. The Psalmist wrote in worship and wonder, “I praise you because I am fearfully and wonderfully made; your works are wonderful”. Psalm 139:14.
