THE CREATOR'S HANDIWORK: MAN
INTRODUCTION
The evolutionists fell us that man is the product of chance. Random action of chemicals produced living creatures; random changes In those creatures produced more creatures; random changes in later creatures ultimately produced man. That is how the story goes.
Man talks about exploring outer space. In this chapter we will briefly look at some aspects of inner space--inside you. Everything within your body is a wonder, an absolute miracle of structure, function, and design. We could fill 100,000 large volumes with the amount of information known by modern science about the human body. Although the following is but the briefest of overviews, as you read each point, think to yourself: "How could it happen by chance?" and then settle it in your mind: "It couldn't happen by chance! It was done by the Creator God!"
1 - BONES
Bones are the framework for your body. If you did not have them, you would lie nearly motionless on the floor like a jellyfish. Your 206 bones are all perfectly shaped to do the right job and in the right way. Each bone is somewhat different from all the others, yet perfectly designed for its task. It is connected in just the right way to perform its functions.
Your finger joints move like a door on its hinges, so are called hinge joints. Your shoulders and upper legs have ball-and socket joints, so they can turn in every direction. How could such a joint make itself by chance? You would have a difficult time working and surviving without that special joint in your shoulders and legs.
Strong, fibrous bands, called ligaments, hold your joints together, and each moving joint is lined with a membrane that secretes a fluid (synovial fluid to keep the joints "oiled" and working smoothly. The ends of each joint has over it a plate of very smooth cartilage to provide a slick surface for rotation.
Inside the bones is a spongy material called marrow. This design provides great strength, yet makes your bones much lighter in weight. Since the area inside the bones is a highly protected area, the red marrow within it contains special cells. Those cells manufacture one of the most important substances in your body: red blood!
Everyone knows that there are only 2 bones in your head: your skull and your jaw. But did you know that, at birth, you had many bones in your head? They were all movable so your head could squeeze through your mother's birth canal. Later, they fused together. Everything was planned, carefully planned.
Your spinal bones are another total marvel. The spine is divided into a vertical stack of bones (vertebra), all carefully connected, with a central vertical hole. Through that hole a cable of nerves-your spinal cord-runs down the middle, with horizontal outlets in the vertebra so nerves can pass outward to various body parts. How could that complicated arrangement invent itself?
2 - MUSCLES
Hold your hand out in front of you and look at it. Move the palm up, then down, and around. Then rotate it slowly from one side to the other. There is hardly a movement that you cannot do with it. Notice that those motions involve your forearm and upper arm. From your shoulder down, all the muscles and bones are working together with your hand as it undergoes various movements. Place your left hand on your right hand, as you move the right hand. Feel the bones and muscles beneath the skin responding to the messages sent from your mind. Look at your hand carefully as you move your fingers in every possible way. Do it again, but this time with your other hand on your wrist, and then your forearm. Rotate your hand again, with your other hand on the forearm bones. Feel the radius and ulna bones turning over on one another as you do it.
Now, within your shoes, wiggle your toes.
Stand up and, with your hands on your hips, slowly walk across the room. As you go feel the bones and muscles moving in perfect coordination. Notice how your legs and body do what is needed to keep you balanced as you walk.
What is this amazing machine called the human body! It is astounding!
Your muscles are attached to your bones at exactly the right places where they will give the best leverage. That took thinking! Downstairs in your family workshop, make a couple bones and several muscles, ligaments, tendons, and all the rest, and then figure out the best place to locate the ends of the muscles in order to obtain the best leverage. Oh, you say, you don't know how to make a muscle! Well, no one else can either. That which intelligent human beings cannot do, random actions of molecules are supposed to have accomplished.

One end of each muscle (the insertion) is attached to a movable bone, the other (the origin) to a less movable one. Muscles are elastic and work in pairs: Most body movements require several pairs of muscles working together. When you bend your elbow (flexion), you can feel the muscle in your upper arm grow hard and thick as the muscle fibers shorten to bring up the forearm. At the same time, the contrasting muscles, those on the back of your upper arm, are lengthened and they pull against the front ones. Now reverse the process (extension) and your arm is extended outward again.
You have two types of muscles: voluntary (skeletal, or straiteal) muscles, and involuntary (smooth) muscles. The voluntary ones change body positions and only work when you want them to; the involuntary work automatically. Work automatically! How can a muscle work "automatically"? Well, they do anyway. These involuntary muscles control motion inside the body, circulate the blood, move food along the digestive tract, make eye adjustments.
Highly-trained scientists and technicians have invented cameras with automatic focus and aperture control. But your eye has always done both functions automatically. Obviously, a highly skilled Person produced that eye. The focusing makes adjustments in the lens system; the aperture determines the size of the hole through which light enters the optical instrument. Yet in your body, it is all done "automatically." literally thousands upon thousands of other adjustments are also made in your body automatically! Thousands are made each minute in each cell in your body. (See chapter 11, Cellular Evolution, for much more on this.)
3 - CIRCULATORY SYSTEM
If I tried to put an ad in the newspaper announcing houses that come with self-manufacturing plumbing and electrical systems, they would tell me I was writing science fiction, and refuse to print it. If I tried to have it printed in a science magazine, they would laugh in my face. But that is what your body does. Before you were born, it constructed its own plumbing and electrical system-and more besides.
Your body is filled with plumbing; in fact, with several totally different plumbing systems. These include your circulatory system, which sends blood all over your body, your urinary system, which purifies the blood, and your lymphatic system, which carries on additional cleaning actions in body tissues. There are also compact plumbing systems in the liver, kidneys, mammary glands, skin sweat and oil glands, and the endrocrine glands.
Your circulatory system is composed of a blood pump (your heart), and the plumbing (blood vessels) needed to carry fluid (blood) throughout your body.
The structure of the heart is another great marvel. It is perfectly designed for what it must do, and is the hardest working muscle in your body.
In the wall of the right atrium of the heart is a small spot of tissue. Called the sino-atrial (SA) node, approximately every second this tissue send out a tiny electrical signal which special nerves quickly carry throughout the heart muscle in the right ventricle. The message it sends is: "Beat!" Instantly, a second node, the atrioventricular (A V) mode (bundle of His) is alerted and relays the message on to the left ventricle: "Bead"
And your heart beats! Moment by moment, day by day, year by year, it keeps beating. How thankful are you for that beating heart?
The heart is a powerful pump that drives 5 to 6 quarts [4.7-5.7 liters] of blood per minute through several miles of tubes in your body. During active exercise, this can go up to 20 quarts ]19 liters]. Consider the complicated, yet efficient design of the pump:
Blood from all parts of your body returns through the superior and inferior vena cava (the largest veins in your body) and enters a "waiting room," the right atrium (right auricle), ready to enter the right ventricle. When the next heart beat occurs, the ventricles squeeze. The load of blood already in the right ventricle is squeezed out into the pulmonary artery (and is sent to the lungs for oxygen). None of that blood flows back into the ventricle, because the semllunar valve guards the exit. That same squeeze brought the waiting blood from the right atrium through the tricuspid valve into the right ventricle. That valve keeps it from flowing back into the right atrium.
Blood returning from the lungs passes through four pulmonary veins into the left atrium (left auricle). A mural (bicuspid) valve guards the entrance into the left ventricle. Then comes the next heartbeat which sends that blood into the left ventricle,-a split second after the blood in the ventricle has been squeezed out through the semilunar valve into the aorta (the largest artery in your body).
The blood in the aorta goes to all parts of your body. From the aorta, that crimson stream is carried to still smaller arteries, and thence into arterioles. These flow through capillaries so tiny that the blood cells must pass single file. As they do, oxygen and nutriments pass across into the cells, while carbon dioxide and wastes leave the cells and pass out into the capillaries. Still other wastes pass out into the lymph vessels to be carried away. From the capillaries, the blood passes into venules, then into veins, then into the inferior or superior vena cave, and back to the heart. Random activity of molecules is supposed to have invented all that? Why, the organism would be long dead before "natural selection" ever got started trying to figure out such complication! Natural selection is simply random activity, and nothing more; it does not have the brains to accomplish anything worthwhile.
Your blood cells are very complex. In chapters 10 and 11 (DNA and Cells), we discuss part of the immense requirements needed to invent blood and other body cells. There are different types of blood cells; each one is vital and each one contains hundreds of key factors needed for life. Complicated enzymes must be present to produce the crucial ingredients in those cells.
One cubic centimeter-smaller than a drop of blood contains an average of 41/s-5 million red blood cells. They wear out in less than a month, and more are made in the red bone marrow. That same cubic centimeter of blood contains 7,0009,000 white blood cells, and increases to 15,00025,000 when infection occurs. There are several types of white blood cells. That same cubic centimeter of blood contains 250,000-500,000 blood platelets (thrombocytes). If you cut your finger, these are used to quickly clot the blood so you will not bleed to death.
The above description is over-simplified in the extreme. But it is enough to take one's breath away! A Powerful, and extremely intelligent Being created you!
In addition to the blood circulatory system, there is the lymphatic system. If all your body were removed except your lymph vessels, the complete three-dimensional form of your body would still be there. That is how many lymph vessels there are in your body! Your lymphatics are used to carry away additional wastes from your cells.
4- DIGESTIVE SYSTEM
For a moment, let us consider your digestive system, a complicated structure that harmful mutations, assisted by random actions ("natural selection") is supposed to have developed Of course, evolutionary processes would have had to produce it within a few days or your first ancestor would have starved to death very quickly.
Evolutionists say that, given enough time, anything can be done. But that is not true. (1) Given enough time, randomness only increases confusion. (2) In relation to living creatures, all the complicated organs had to be in place-fast!
In or near your mouth are teeth to chew food, a tongue to move it around, and seven different salivary glands to produce saliva to predigest part of that food. Any one of those items would be impossible for chance to invent. It is only their great ignorance that enables people to glibly speak about how "evolution operates by mutations and natural selection." Anyone who takes time to study into the multitude of nerves leading to the tongue will be dumbfounded with amazement. All those nerves were needed, for you were purposely designed to be able to think in words and then speak them with your tongue.
From the mouth, the food is sent to the back of the throat where it passes through the swallowing mechanism. How may ages did it take for natural selection to figure out that you needed to swallow food without choking to death instead? Until that happened, food would all pass into the lungs instead of into the stomach!
Another little detail: Your pharynx not only contracts so you can swallow food properly, it also connects through Eustachian tubes to each ear. Without those tubes, changing air pressure would quickly destroy your hearing!
Passing down the 10-inch [25 cm] esophagus, the food arrives at your stomach. The cardiac valve guards the top end, and the pyloric valve the bottom end of your stomach. Both are ingeniously-designed sphincter muscles.
Within the stomach, the digestion begun in the mouth continues on. Signals are sent to the stomach wall, and its excretes an acid so powerful that it can digest meat! Why then does it not digest the stomach and everything inside your body? No one has ever satisfactorily explained that question. Next the stomach begins churning back and forth, mixing the contents with hydrochloric acid. All the while, the pyloric valve remains closed.
Then, something tells that valve to open, and the contents start entering the small Intestine. The upper 10-12 inches [25-30 cm] of it is called the duodenum. Within that short length of tubing, bile pours in on signal from the gall bladder. (It was oil in the food which triggered that signal.) The wall of the duodenum also signals the pancreas on the other side of the body to quickly send over some pancreatic juice. Still other types of juices come from the wall of the duodenum. All of those juices work to break up fats, proteins, sugars and starches into still smaller particles.
The food gradually moves downward through the small intestine, which is 11/z inches wide [3.8 cm] and 23 feet [7 m] long. Throughout its entire length, little fingers protrude from the walls. These are called villl. In the center of each is a lymph channel (lacteal), with blood capillaries surrounding it. Between the villi are additional intestinal juice glands. The villi absorb the nutriments and send them into the blood stream.
You could not design a more efficient way to do it if you tried, yet evolutionists say it all happened by chance. When asked how that could be, the reply is always the same: "long ages of time, long ages of time; anything can be done if given enough time." How did we live during all those "long ages" until our villi were invented?
The liver is generally classified with the digestive system, but it accomplishes a wide range of tasks. Aside from your skin, this is the largest gland in your body, and one of the most astonishing structures in your body!
The liver literally performs thousands of different functions! It is amazing how such a small organ can do so many things. Here are a few of its major activities: (1) It is a collection and filtration plant, carefully removing a variety of substances from the blood. (2) Working with waste products and nutrients brought to it in the blood stream, it manufactures literally hundreds upon hundreds of different chemical substances. Among these are bile, glycogen (stored sugar), and blood clotting aids and preventatives. (3) Since it does so much, how can the liver find room to store anything,-yet it does. It is a warehouse and stores iron, vitamins, copper, amino acids, fats, and glycogen. (4) It is a heating plant, producing more heat than anything else in the body except the muscles. (5) It is a waste disposal plant. Like the kidneys, it filters all your blood, removes certain waste products, and sends them off for excretion. Aside from your blood cells, the liver and kidneys are the major detoxification points in your bogy.
We will discuss the pancreas later.
6 - RESPIRATORY SYSTEM
Here is another miracle system. Air enters your nose and passes down to that same pharynx again. But this time, the swallow mechanism is not in operation, so the air goes directly downward into the larynx, past your voice box, and into the trachea, which then divides into the two bronchi, which then lead through the bronchioles into tiny air sacs called atria. Think of two trees with their branches continually rebranching until finally they end-in grapes! That is the appearance of the bronchi, bronchioles, and atria. Tiny projections, called alveoli, protrude outward from each grape-like atrium into the lung. It all does look very much like a bunch of grapes! The plan is to exchange oxygen for carbon dioxide-as much as possible and as quickly as possible. There are over 400 million alveoli; each one is closely connected with blood and lymph vessels, nerves, and connective tissue.
That is what, on the inside, your lungs look like; From the outside, the lungs appear to be two cone-shaped organs, nicely designed to fit the space in your chest. Your left one is not as large, in order to make room for the heart just below it. Your lungs hold about 31/z quarts [3.3 liters] of air, and are remarkably like air bellows, partly filling, partly emptying, partly filling, partly emptying; this goes on constantly, night and day. It should not take long for such action to wear a hole in the side of the lungs, but instead they are wrapped inside the pleural cavity. Moist fluid is exuded by the walls of the pleural membrane, which provides a slippery surface for the lungs to move against.
Please remember that, throughout this chapter, you are observing only the barest outline of the body systems. It is similar to lifting the top off the central processing unit of a home computer, letting you gaze within at the electronic boxes and cards neatly stacked inside,-and then concluding that you understood the complexity of a computer!
Several lengthy books could easily be written about each italicized word in this chapter.
6 - URINARY SYSTEM
Your kidneys are the primary filtration and removal plant in your body. They are your blood cleaning organs. Most of your kidneys consist of nephrons. Each one is a capillary cluster with a coiled tube attached to it. There are over a million of them in your kidneys! As the blood passes through the capillary cluster, water and waste products filter through the capillary walls and into those tubules. Most of that waste water is cleaned and returned to the blood. Your kidneys, then, are like a million little thinking machines, each one of which knows just what to remove from the blood and what to leave in it.
The waste fluid drains out into a collecting basin in each kidney called the renal pelvis. From each one, a tube leads down into the bladder. When the bladder fills to about 200 cc [12.2 cu inches], it sends a signal to the brain to void the urine. How can a bag send a signal? How does it know to do it at the right time?
7 - ENDOCRINE SYSTEM
The endocrine glands are located in various parts of the body and pour their secretions directly into the blood stream. They produce chemical substances which speed up or slow down the activities of various body organs. These substances, called hormones, also affect each other's actions. Each endocrine gland is a fantastic organ for what it can accomplish, especially in view of its small size.
1 - The Thyroid Gland. The thyroid is in the center front of the neck, and looks something like a butterfly with wings 2-3 inches [5-7.6 cm] wide. It is just behind your voice box. The thyroid secretes thyroxin (thyroxine), and regulates the rate at which the cells burn food. Thus, it regulates metabolism. If too much thyroxin is sent out into the blood stream, all body activities are speeded up, and the cells burn food so rapidly that the body uses up its daily supply of nourishment and draws on the stored reserves. If the thyroid does not secrete enough of this hormone, the cells burn food too slowly. this interferes with body development and slows body activities.
How can the extremely small amount of thyroxin sent out by this gland get to each of the billions of cells in your body, and affect them? In what way does that fluid signal them to speed up or slow down? All this is a great mystery. Thyroxin is almost pure iodine.

2 - The Parathyroids. Four small glands, each the size of a pea, are the parathyroids. There are two of them on each side of the thyroid. These extremely tiny organs secrete a hormone (parathormone) which regulates the amount of calcium in the blood. The amount of calcium in the blood directly affects nerve and muscle irritability. Too little, and muscle spasms and convulsions bring death within a few hours. Too much, and the body uses up calcium faster than it can get it from ingested food, and calcium will then be drawn from the bones and they will become soft and eventually break.
All the hormones are utterly mysterious, yet we all take them so much for granted. They are miracles; describable, but inexplainable. Each endocrine gland is as truly miraculous as any miracle found in the Bible. The endocrines are blessings to mankind sent from the same Source as all the other miracles.
3 - The Adrenals. Also called the suprarenals, these two glands are at the upper end of the kidneys. Each one is so tiny it is the size of the last joint on your little finger. Each adrenal gland is really two separate endocrine glands because its two parts produce different hormones.
The central part (the medulla) secretes the hormone epinephrine (adrenalin), which brings many body processes into action quickly. This is the "fight or flight" hormone. It makes the heart beat faster, raises blood pressure, increases muscle power, and makes blood clot more rapidly. -A tiny amount of fluid from part of a large bean can do all that? Emotions of fright, anger, love, grief, or pain signal the epinephrine to be sent out.
The outer part (the cortex) secretes several hormones. One of these, cortin, regulates the behavior of salts and water content in the body. Certain male and female hormones are also secreted by the adrenal cortex.
4 - The Pancreas. When the duodenum signals it to do so, part of the pancreas sends secretions to the duodenum to aid in the digestion of food. Yet another part of it contains the islets of Langerhans, which secrete Insulin. This regulates the amount of sugar in the blood. If too little insulin is sent out, sugar accumulates and the kidneys try to get rid of it through the urine.
5 - The Pituitary Gland. The pituitary is often called the "master gland." It is located in one of the safest places in the body: the center of your skull. Attached to the base of the brain in the region back of the eyes, it is only about the size of a pea, yet it secretes more potent hormones than any other gland. How can it do that when it is one of the smallest of the endocrine glands? It has two parts, the anterior lobe and the posterior lobe.
The posterior lobe secretes two hormones: The first of these, vasopressin affects the smooth muscles, raises blood pressure by constricting blood vessels, and stimulates the reabsorption of water in the kidney tubules, thus affecting water balance. The second, oxytocin stimulates contractions of the uterine muscles.
The anterior lobe of the pituitary secretes several hormones. One regulates the thyroid, another controls the adrenal cortex, another stimulates sex and mammary gland activity, and another regulates growth of bone and fibrous tissue. It is the pituitary anterior lobe which determines how tall you will become. It is also decides how much pigment you will have in your skin.
6 - The Gonads. The gonads are the reproduction glands: the testes in men and ovaries in women. The testes secrete male sex hormones (androgens), which includes testosterone. The ovaries produce estrogen and progesterone. These hormones are powerful in their effects on the body, yet they come from small glandular organs.
7 - The Thymus. The thymus lies behind the breast bone (sternum), but its purpose is still not clearly understood. It apparently has something to do with attaining sexual maturity, for it atropies following puberty.
8 - The Pineal Gland. The pineal is attached to the brain and is another endocrine puzzle. Apparently it has some effect on growth. Tumors on this gland in children accelerate sexual growth.
9 - Other Hormones. The stomach wall secretes a hormone, gastrin, which affects the blood vessels and secretions of the stomach glands.
At the beginning of the small intestine, the lining of the duodenum secretes two hormones: Secretin stimulates the pancreas to send pancreatin, a digestive fluid to the duodenum wall for excretion into small intestine. A second hormone signals the gallbladder to contract and send gall into the small intestine.
The placenta is also a temporary endocrine gland which excretes hormones to regulate and maintain pregnancy.
8 - THE NERVOUS SYSTEM
There are several other complicated body systems, such as the skin and the reproductive system, but we will conclude this chapter with the nervous system.
Without nerves, your body could not send, relay, or receive any signals. Without nerves, you could not think or even live. A large part of your nerve activity is done without your conscious thought, and is called the autonomic nervous system.
Did you know that the best way to build a telephone switching station is to send in several dump trucks with sand, dirt, rock, and odds-and-ends junk? Then send in a bulldozer to scatter it around a little. After that leave it for several million years and return-and you will have a complete switching station, ready for operation? Well, that is how evolutionary theory would build one.
But within your body is a switching station and far more: a complete electronic computer system operated by something equivalent to an Intel chip 500,000. (As these words are being written, the largest home computers are Intel 486 in capacity.) Literally millions of connections are to be found inside just a pinhead of space in your brain. Main cables flow out from the brain and down through your spinal column, and then out to various parts of your body. And all that is supposed to have come about by chance?
Through a network of wires, messages come into the central switchboard, where the necessary connections are made to direct them out to the right places. Your nervous system is organized to bring messages into a center which relays them out to certain parts of the body. The brain and the spinal cord are the switchboard, and the nerves are the wires that carry incoming and outgoing messages. The deference is that thinking is a part of your switchboard system.
Your brain weighs about three pounds. It is similar to a bowl of jelly, yet it is the most fantastic creation in our world. The largest part is the cerebrum which fills the upper part of the cranium. Next is the cerebellum, located below the cerebrum. The third major part is the brain stem, with its pons and medulla.
The cerebrum is the main brain and is divided into two halves, one on either side, called hemispheres. The outer part is the cerebral cortex. This is soft grayish matter filled with nerve cells. Beneath it is the white matter, which has the nerve fibers, or "wiring," leading out from the gray matter. The cortex or "gray matter" is heavily wrinkled. That is done to give it a much greater area. If it was flattened out, it would cover a surprisingly large area. Some centers in the cerebrum think, some are memory. Others are related to hearing, sight, movement, and speech.
Directly beneath the left and right cerebral hemispheres, and covered by them, are two other centers: the thalamus and the hypothalamus. The thalamus is a relay station; receiving impulses from every part of the body, it sends them to exactly the right part of the cortex. The thalamus also interprets sensations, and tells the brain whether they are pleasant or unpleasant. The main job of the hypothalamus is to regulate the action of various body organs in order to maintain normal conditions. For example, you shiver when you are cold because of the hypothalamus.
The cerebellum maintains body balance and coordinates groups of muscles. It is because of the cerebellum that you can walk across the room, or reach down and pick up a book. Skill in sports is related to good cerebellum connections.
At the top of the brain stem is the midbrain, which is an important reflex center. A reflex is an action that takes place automatically when something happens. If you look into a mirror and shake your head, your eyes will keep looking forward. It is the midbrain that tells them to do that.
The pons is the bridge between the cerebral cortex and the cerebellum, carrying messages from one to the other.
The medulla is just below the pons and is on the very bottom of the skull. It connects the brain with the spinal cord. It also controls certain factors on its own. One of these is the amount of carbon dioxide in the blood. The medulla, in some mysterious way, knows that percentage,-and then sends out signals instructing you to breath faster or more deeply. It also guides the rate of heartbeat. It even affects the muscles in the smallest arteries. The spinal nerves from the two halves (hemispheres) of the cerebrum cross over in the medulla before proceeding on down to the body.
The spinal cord is a long mass of nerve fibers reaching down through the central holes in all the vertebra in your spine. The spinal cord does two things: (1) conduct impulses from the brain to the body, and (2) operate as a reflex center apart from the brain. When you touch something hot, the spine sends the message to move your hand back quickly. That arrangement was wisely planned, for the nerve impulses warning of terrible danger did not have to travel as far before a message could be sent back to take proper action.
You have different types of nerve cells; we will not take the space here to describe them. Suffice to say that they are extremely complicated. Each nerve connects with thousands of other connections in nearby cells. The result is a massive electronic circuit board arrangement,-and all connected to part of a thinking mind.
The major nerves for your body exit the brain and travel down through the spine and then go outward at various points. There are 12 pairs of cranial nerves and 31 pairs of spinal nerves. The cranial nerves attach directly to the brain, and most of them carry impulses to and from the brain and various structures about the head (sensory organs, swallowing, speech, hearing, sight, tongue, jaw, etc.). However, other cranial nerves connect with organs in the thorax and abdomen.
The spinal nerves are attached to the spinal cord, and carry impulses from the skin and some internal structures to the central nervous system.
But now, forgetting all the rest; let the evolutionists satisfactorily explain the brain, the nerves, and and spinal cord-on the basis of random actions ("natural selection") and harmful accidents ("mutations"). We await their reply.
CONCLUSION
We have not taken space in this chapter to discuss the sense organs, and they are just as wonderful, if not more so, than some of those we have already discussed.
The eye we discussed in some detail in chapter 13 (Natural Selection). The ear has some of the most delicately complex structures to be found anywhere in the body. For example, consider this: Blood bathes every part of your body, and flows next to and into every cell,-with one exception: the cells in the ear which are involved in hearing. Why is that? If blood capillaries flowed next to those particular cells, you could not hear properly! You would hear the faint beating sounds of the blood rushing along as it is pushed by the heart pump. So, instead, fluids containing no blood are sent that final short distance to bathe, nourish, and clean those hearing cells.
That was done by chance? There would be no reason for random activity to do that.
Why do you have eyelashes? They keep dust out of your eyes, but are in no way needed for survival. A thinking Creator would bestow eyelashes upon His creatures; the chance workings of so-called "natural selection" would never produce these perfectly-located little helpers.
Why do you have odor-detecting cells in your nose? Why can you taste with your tongue? Why does food itself have built-in flavor? The food and your tongue were designed for one another!
There are three semicircular canals, shaped like small horseshoes, that are close to each ear. Each is partly filled with fluid that is set in motion by head or body movements. Sensitive nerves send signals from this fluid to the brain. Without those structures and those signals, you could not maintain body balance; you could not stand up without falling down. Think about the semicircular canals for awhile; how could they arise by merest chance?
Everything is a miracle; an absolute miracle. It all came from a God of miracles; your heavenly Father. He made you for purpose: to live a good, clean, unselfish life. He alone can help you live such a life. Come to Him just now; tell Him your needs. Let Him give you forgiveness for the past, and help for the present and future. He is waiting, just now.
