Existence of God and the Rise of Atheism #6: Complex and Amazing Human Body

“Sunday Afternoon Sermon”

God created man in his own image.” (Gen. 1:27)

The Psalmist pondered: “What is man, that thou art mindful of him?”For thou hast made him a little lower than the angels, and hast crowned him with glory and honor.” “Thou madest him to have dominion over the works of thy hands; thou hast put all things under his feet.” (Psalm 8: 4-6)

One of the great “proofs” of the existence of God is the “crown” of His creation — mankind. The human body is so incredibly complex it could not have been the product of the random accidental collision of molecules.

Embryonic Development

Amazingly, a single cell divides into two identical cells, and those two cells divide into four identical cells.  Somewhere in the process, these identical cells differentiate.  Some become  hearts, brains, skins, etc.  How can identical cells suddenly differentiate?

The Heart

Pliable and delicate heart valves open and close over over 36,000,000 million times a year. Yet, unless altered by disease, heart valves are so rugged they can stand this kind of wear almost indefinitely. No man-made material can be flexed so frequently and for so long without breaking.  The heart is so complex it warrants is own medical specialties (cardiologist, cardiac electrophysiologist, cardiac surgeon, cardiovascular surgeon).

The Brain

“The human brain is the most complex and orderly arrangement of matter in the universe.” (Isaac Asimov)

The human brain has an intricate combination of power cells and recording, memory, storage, and retrieval systems.  

The brain simultaneously interprets huge amounts of information, including:

  • objects
  • colors
  • sounds
  • smells
  • texture
  • external and internal temperature
  • pressure
  • hunger and thirst
  • illness and injury

The brain processes over 1,000,000 messages each second.  These include:

  • thoughts
  • feelings and emotions
  • imagination
  • memory
  • dreams
  • creativity
  • complex bodily functions (pulse, respiration, organs)
  • action (flight/fight)
  • plans and goals

The brain is so complicated it requires its own medical specialties (neurologists, neuropsychologists, neurosurgeons, psychiatrists).

The Eye

The eye can distinguish among seven million colors. It has automatic focusing and handles an astounding 1.5 million messages simultaneously. The eye is so complex it requires its own medical specialties (opticians, optometrists, ophthalmologists).

Backup Systems and Redundancies

The human body has several backup systems and redundancies: two kidneys, two lungs, two eyes, two ears, two arms, two legs, etc. The brain has a left and right hemisphere that can compensate for damage to the other side.

Multiple Self-defense Mechanisms

The body has several effective self-defense mechanisms.

For example, the hard skull is specifically designed to not only protect the brain, but also the eyes and ears.  The eyes are recessed inside the orbital bone.  The ear canals are protected by the mastoid bone, one of the strongest bones in the body.

Another self-defense mechanism is blood clotting and coagulation.  Without the complex clotting process, a simple laceration could be fatal.

Another self-defense mechanism is antibodies. Produced by white blood cells, these antibodies recognize and fight foreign and harmful bacteria.

Another self-defense mechanism is the immunity process.  People can develop natural immunities to threatening illnesses.

The Skin

The skin is the largest organ in the body. It does more than just keep the bad stuff out and the good stuff in.  Skin:

  • protects against pathogens,
  • senses heat and cold
  • controls evaporation
  • shows moods (like embarrassment),
  • synthesizes vitamin D
  • regulates body heat
  • eliminates toxins
  • absorbs medicine   

The skin is so complex that it has several medical specialists (dermatologists, allergists, immunologists.)

Self-repair

In most cases, from broken bones to major injuries, the human body can repair itself.  Most medical intervention involves helping to body to heal itself.

Renewal, Regeneration, and Replacement of DNA and Cells

About 50-80 billion human cells die, and are replaced, every day.

Molecular machines package, replicate, distribute DNA. The DNA strand in each cell is 6 feet long and contains 3 billion letters. Molecular machines coil DNA strands at the speed of a jet engine. Molecules traveling one direction on the DNA have tall “legs” so that the “short-legged” molecules traveling in the opposite direction can
“walk” under them without slowing down. (See: Veritasium Channel, “Your Amazing Molecular Machines,” YouTube, 6:21 min.)

Auto-regulation and Biofeedback

The body has incredible systems of autoregulation and biofeedback. These systems control body temperature, carbon dioxide levels, hydration levels, and vitamin and mineral levels.  These systems also reduce toxins and eliminate waste products.

Human Reproduction and Childbirth

Reproduction is one of the most mindboggling systems in the body.  The strongest and fastest sperm fertilizes the egg.  The baby receives 23 pairs of chromosomes from the father and 23 from the mother.  Out of billions of people born, each one is unique.

After fertilization, the cells divide and differentiate into separate organs. When the baby is fully developed, the cervix dilates and the mother’s pelvic bones actually soften and expand so that the baby can fit through the narrow birth canal.

This birth process is so incredible that it is often called, “the miracle of childbirth.”

Reproduction and childbirth are complicated enough they have their own medical specialties (gynecologists, obstetricians, reproductive endocrinologists, pediatricians, anesthesiologists) 

The Human Body as a Whole

All of the complex systems, processes, and organs of the human body are interconnected. When considered as a whole, the complexity of the human body is almost incomprehensible.  

Caring for the body requires several hundred medical specialties, including:

  • dermatology
  • cardiology
  • urology
  • proctology
  • oncology
  • neurology
  • neurosurgery,
  • hematology
  • anesthesiology
  • immunology
  • radiology
  • otolaryngology
  • ophthalmology
  • pathology
  • rheumatology
  • pulmonology
  • nephrology
  • obstetrics
  • gynecology
  • gastroenterology
  • allergist
  • surgery
  • orthopedics
  • physical medicine
  • pain management medicine
  • thoracic surgery
  • cardiac surgery
  • audiology
  • dentistry
  • oral surgery
  • endocrinology
  • epileptology
  • toxicology
  • nephrology
  • hepatology

Think of the countless hours intelligent medical specialists devote to “mastering” just one part of the human body. It is inconceivable that such complexity, efficiency, and perfection could be the result of random chance accident.  

Amazing Complexity and Wonder of the Human Genome

3D Genome

Several preeminent scientists became believers after studying the miraculous complexity and smooth function of the human genome.

One of them was Dr. Frances Sellers Collins, the director of the Human Genome Project.  He wrote the book, “The Language of God: A Scientist Presents Evidence for Belief.”

Another was Dr. Antony Flew, a leading spokesman for atheism.  He concluded that a belief in God is “the only rational conclusion.” “Super-intelligence is the only good explanation for the origin of life and the complexity of nature.” “One has to ask…. how did this information program wind up in each human cell? These are not just chemicals. These are chemicals that instruct, that code in a very detailed way exactly how the person’s body should develop. Natural, biological causes are completely lacking as an explanation when programmed information is involved. You cannot find instruction, precise information like this, without someone intentionally constructing it.”

Scientists often refer to the human genome as “God’s signature.”
