The more we learn about the human body, the more we see the complexity that defies any notion of mindless creation. The latest count of microscopic species that live in or on our bodies is over 10,000. The total number of single-cell microbes is over one-hundred trillion. These are not just hitchhikers that have come along for the ride. They are essential to the proper functioning of our bodies. Scientists have well studied most of these microbes, but the scientific literature continues to report on new roles for microbes that scientists previously thought to have no function. We marvel at the amazing complexity of being you.
This complexity is minor compared to DNA. The project to sequence the human genome formally began in 1990 and was completed in 2003. If you wonder why it took so long, consider the enormous size of the DNA molecule. Packed into every cell of your body is a DNA strand that, if you unwound it and stretched it out, would be about three meters long. Considering the number of cells in the human body, if you took the stretched-out DNA molecules from every cell and laid them end-to-end, they would reach from here to the Sun and back almost 70 times. A few years ago, the popular literature told us that 98% of our DNA was junk with no functional use. Since that time, science has learned that over 80% of human DNA has a function, and you don’t hear about “junk DNA” anymore.
The point of all these numbers is to show the amazing complexity of being you. The human body is an incredibly complicated machine with a blueprint that scientists are still not able to read. As we do read parts of that blueprint, we find that our assumptions about our bodies have led to unfortunate medical decisions. As a child, I can remember the polio epidemic and the pain and misery that it brought to some of my friends. It is incredible that I never contracted this virus because when I was very young, I had a lot of throat problems, and the doctor decided to remove my tonsils. We now know that the tonsils are the only area of the body that can synthesize antibodies to fight poliomyelitis. If you don’t have tonsils, your chances of developing polio increase significantly.
We hear promoters of the theory of human evolution glibly talk about the chance mutations of life that would lead to what humans are today. Assuming that the incredible complexity of the human body can come about by chance alone is to accept a faith that defies reason. The simple biblical statement that “God formed man of the dust of the Earth” ignores the intelligence and design that is required. The Psalmist had a glimpse of the amazing complexity of being you when he wrote, “I will praise you, for I am fearfully and wonderfully made” (Psalms 139:14-15). Today we know far more about our creation than David did, and we can add our voice to that praise.

Since the first sequencing of the human genome in 2003, there have been exhaustive studies of links between the human gene structure and addiction.
