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.
Skeptics claim that Intelligent Design destroys science. This claim shows how badly the skeptics misunderstand Intelligent Design.
The dictionary defines science as knowledge. When we do scientific experiments and make observations, we are trying to gain knowledge. We apply that knowledge to those situations where we can gain more knowledge. We never just say “God did it” and stop investigating. We continue experimenting because we want to understand how and why God did it. Believing that there is design in all aspects of the creation never stops us from looking for a deeper understanding. Naturalism is frequently just the opposite. A classic example of this is Junk DNA.
As naturalists examined the DNA in various animals, they found that there was DNA that didn’t seem to be necessary. They called it “Junk DNA” assuming that it was a byproduct left over from the evolutionary process. For many researchers, that was the end of the story. No further experiments were designed to find a purpose for junk DNA. In this case, a naturalistic view and assumption stopped the scientific investigation, or at least slowed it down.
A biology professor chastised me for referring to junk DNA as a dead-end street. His exact words were “God doesn’t make any junk.” The assumption that junk DNA wasn’t junk led to further investigation. That research now tells us the so-called “junk” has a purpose and plays a vital role in life processes. Believing that everything we see was created with a purpose and a design, and wanting to understand that design is a great catalyst for scientific investigation.
Historically, most of the significant discoveries of science over the past 1000 years have been made by scientists who recognized purpose and design in the cosmos. They were striving to understand that design. In our quarterly journal (which you can read on doesgodexist.org), we have a column titled “Scientists and God.” We present statements by leading scientists about their faith and their recognition of purpose and design in the creation. Does Intelligent Design destroy science? No, it supports science.
“We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written the books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangement of the books, but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human beings toward God. We see the universe marvelously arranged and obeying certain laws but only dimly understand these laws.”
