A Close-Up Look at the Amazing Human Eye!
Viewpoint of Mark Cadwallader, Creation Moments Board Chairman
“If the whole body were an eye, where would the hearing be?” 1 Corinthians 12:17
The physical function – apart from the psychological and spiritual function – of human beings is a wondrously amazing testimony to our great Creator. Even Charles Darwin, in his Origin of the Species, said this about the human eye:
“To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree.”
Yet, he went on to dismiss this “absurdity”, writing three and a half pages describing a highly imaginative story, stringing together several “intermediate” stages to explain how the process from “simple” light-sensitive spots to “complex” eyes may have taken place.
As it turns out, Darwin was quite ignorant of the inner workings of cells, along with the actual chemical pathways required for sight. For images to be registered in the brain, it takes an incredibly complex arrangement of photo-chemical receptors, nerve cells, transfer proteins, electrical signals to and within the brain, muscles, tear ducts and cellular skeletal structures, not to mention the incredibly complicated arrangement of molecules which make up the eye itself. His proposed scenario for natural selection of the eye was far too simplistic and completely unrealistic.
In Darwin’s day, the eye was held forth as the great and marvelous biological machine – the epitome of biological complexity. They thought that cells were essentially blobs of protoplasm surrounding a nucleus. They had no clue that cells are themselves specialized self-contained chemical plants or factories of highly organized and complicated operation, acting under near-instantaneous command and control, both conscious and subconscious.
The more we find out about the human body, the more we should appreciate all of the awesome wonders of God’s creation. Baseball players, for instance, can actually watch a baseball thrown toward them at 90 miles an hour by someone who doesn’t want them to succeed … and swing a bat around – with their legs, hips, arms and wrists all working together – to hit the fast-moving spheroid into the field of play, and then run to first base. That the eyes, brain and other body parts can work so well together – adjusting to curve balls, sliders and other pitches over different parts of home plate – is really quite amazing. There is no machine that could replace a baseball batter – yet, the human body is said to have evolved by chance and natural selection!?
Unknown to Darwin, the human eye is much more amazing than anyone of his day could describe. It can detect the faintest light possible, a single photon of light – and can also work with 10 billion photons of light. In the language of Optics, its “dynamic range” is 10,000,000,000 to 1. Compare that to specialty modern photographic film that has a dynamic range of only about 1,000 to 1.
The biological “machinery” which allows the human eye to do this not only involves muscular contractions and dilations of the iris to allow more or less light through the lens of the eye, but it also involves a great deal of complicated cellular biochemistry. Light-detector cells use specialty proteins to transport “calming” proteins along skeletal cell formations from a “holding area” to where the light-detecting proteins are. They “pick up” these soothing desensitizing proteins with a special “sticky” fat. In effect, the light-detecting cells work like a very efficient factory, using motorized transport along internal train tracks to pick up and carry with glue a calming agent to where it is needed – in a split second!
Take out the most advanced video camera or smart phone available, hit record and move it quickly back and forth. You end up with a blur. But when you quickly swing your head up and down or side to side, practically everything in your field-of-view stays focused! Unlike the best available camera and computer technology, our brains – through a complex process – can recognize and bring into focus objects that we barely glance at!
Computers may seem to beat the brain at things like huge number-crunching and database searches, but there are many other tasks where the best computers cannot come close to what we can do. In the area of navigation, for instance, the most powerful supercomputers cannot approach even the navigational ability of a simple honeybee as it goes out from its hive, making multiple stops to gather nectar and return again.
Indeed, Biochemical, Neurological and Computer Engineers are now working together in teams to try to “reverse engineer” the brain – a goal set forth in 2008 by the National Academy of Engineering as one of the Grand Challenges of the 21st Century. Interesting, isn’t it, how something officially considered to have evolved by chance is also recognized as far “more complex than anything humans have ever built”? Sophisticated complexity requires intelligent design and engineering. Yet, our most sophisticated design and engineering does not even come close to building something that somehow “officially” arose by chance!? The foolishness of such a charade boggles the mind!
The fact that the scientists and engineers involved use the term “reverse engineer” the brain, of course, admits to the plain fact that the brain was “engineered” – or made – in the first place. And this is exactly what the Bible says – that the evidence for our Creator can be “understood through what has been made, so that they are without excuse” (Romans 1:20). Moreover, considering the human body itself, we can exclaim with the Psalmist, “I am fearfully and wonderfully made” (Psalm 139:14).
And this, my friend, is the message that Creation Moments is proclaiming to all the corners of the globe! By proclaiming God’s truth, we are making millions of people aware that they are being kept in darkness and confusion by evolution – the world’s “official lie”. Yes, evolution is the central deception of our modern day – playing right into the hands of the world, the flesh and the devil to keep millions from knowing their Maker!
That’s why I’m excited to say our ministry is making a difference at home and around the world! Here’s one testimony among many we receive each day: “I have been in China and Germany working full time for the Lord. Creation Moments was a great blessing which I often shared in morning devotions with my friends.” – L.F.
This is a great example of what we call creation evangelism … and it’s the heart of everything we do. For the past 48 years, the Lord has made it possible to continue this work by faithfully providing for our financial needs. Even in the midst of difficult economic times, we trust God to put it on people’s hearts – perhaps your own – to support the crucial work we share together. If you can’t donate at this time, then we ask you to keep us in your prayers. And if you can support us, please do!
