The Journey to Safety

We have often talked about the design of animals. Various animals act on what we often call “instinct.” Programmed into sea turtles is a journey to safety. When baby sea turtles hatch on the beach, they instinctively and quickly head to the ocean to escape the predators on land. Their mothers didn’t teach them to do that. It is programmed into them. When a kangaroo is born, it will instinctively journey to safety by climbing into its mother’s pouch. She does nothing to assist the tiny creature. Programming a specific action is very efficient, so we program computers to do specific tasks.

In contrast to programmed actions, there is free will. When we tell our children what to do, they may do something entirely different. The child can understand our instructions but still refuse to follow them. The reason is that the child finds other things he wants to do are more appealing.

The bottom line is that commanding actions is less efficient than programming those actions. A baby sea turtle, kangaroo, or robot will act in the way it is programmed. If you are a parent, you have realized that your child will not always do what you command. The question, then, is why didn’t God program humans to do what He wanted? Why did He give us free will? Programming us to act as He desired would have been much more efficient.

God commands us rather than programming us to do His will because He wants to have a relationship with us. Robots can be very efficient because they have specific functions programmed into them and will do what their designer intended. That is not true of humans. However, you can never have a real relationship with a robot. God wants to have a relationship with us. He knew what would happen when He created the first humans, but He did it anyway. We have rebelled and made a mess of our lives and our world. Hatred, war, and mayhem have been the results.

Why, then, did God choose to create us? To Him, having a relationship with us was worth the price. Jesus Christ came to Earth to restore the broken relationship. He was the perfect man, but at the same time, He was God in the flesh. He showed us how to have a loving relationship with God and each other. Then, He bore the punishment for our disobedience to restore the broken relationships.

We are not robots. We are God’s creation, in His image, with free will. We can choose the journey to safety or ignore God and choose our own path. God has made the journey to safety and peace available to us. Why choose the path to destruction?

Seaweed as a Food Source

God has given us a food source that so far humans have been unwilling to tap – seaweed. It is super fast growing, with some species like giant kelp growing 50 centimeters a day. Seaweed doesn’t need land or pesticides and doesn’t have to be watered. Furthermore, it is packed with protein, fiber, vitamins, minerals, and other nutrients. With over 800 million people starving worldwide, one answer might be seaweed as a food source.

Oceans cover roughly two-thirds of our planet, yet they contribute less than three percent of humans’ total food calories. Asian recipes have used seaweed for centuries, and its cultivation is limited mainly to Asia — large areas of the sea could be seaweed farms. There are 12,000 different types of seaweed, and humans have only learned how to cultivate fewer than 30.

Dried seaweed retains its nutrients and has a long shelf life, so it doesn’t have to be refrigerated or frozen. The reluctance to use seaweed as a food source has primarily come from misconceptions about it. Many of us have only seen water plants growing in a freshwater pond and have no idea what ocean-grown seaweed is like. In addition to food and the replacement of environmentally polluting agents, seaweed can be a significant carbon sink, absorbing massive amounts of carbon dioxide.

Seaweed can also be used as a natural fertilizer for land plants and as feed for animals. It can even be a cotton alternative in textiles and, in some cases, as a biodegradable replacement for plastics. Like most human problems, the solution is there, but we aren’t using all of the wealth of resources God has given us. One solution God has provided may be seaweed as a food source and more.

The Feel-Good Hormones

Hormones are chemical messengers that travel through our bloodstream. You can describe them as signaling molecules that work to set things in motion. The name comes from a Greek word meaning “setting in motion.” Hormones are produced in various areas of our bodies and are sent through the bloodstream to signal some action or response. Good health requires a balance of hormones, and proper diet, exercise, and rest help to keep them in balance. The feel-good hormones are four classes of hormones that, as you might guess, do things that make us feel good.

ENDORPHINS- Endorphins are the body’s natural painkillers. The pituitary gland, located at the base of the brain, synthesizes and stores them. Endorphins help to mask pain, reduce stress, and improve mood. When we push through a painful task or strenuous exercise, endorphins are there to help us.

DOPAMINE- Two areas of the brain produce dopamine, and you can think of this hormone as the brain’s reward system. Exercise, eating a food we like, or accomplishing a task can cause the brain to release dopamine, giving us a pleasurable feeling. The use of some drugs and alcohol can release a flood of dopamine, giving us a sense of euphoria, a “high.” But coming down from that high can lead to depression and a desire for more of the drugs. Normal activities or exercise stimulate dopamine more slowly, and the effect of the hormone remains longer. Good stewardship of our bodies and health calls for avoiding harmful drugs and alcohol.

OXYTOCIN- Some people call this feel-good hormone the love hormone. Touching, hugging, or sexual activity can trigger the release of oxytocin. The brain’s hypothalamus produces it, and the pituitary gland releases it into the bloodstream. Oxytocin can help improve social interactions and give us a desire to develop stronger connections with others.

SEROTONIN- Serotonin is a natural mood booster, and depression can result from a low level of this hormone. Serotonin performs many functions and is produced by the central nervous system in various areas of the body. Serotonin improves memory and learning and promotes relaxation. Exercise, as well as exposure to sunshine and the outdoors, can increase the production of serotonin. Meditation and quietness in prayer can also reward us with this mood-boosting hormone.

The feel-good hormones are part of good health, and a healthy lifestyle boosts them. However, too much of a good thing too quickly is not healthy. Alcohol and drugs can give us a high but only lead to a letdown. A healthy lifestyle involves proper diet, exercise, rest, prayer, meditation, thankfulness, and balanced relationships with others. Incorporating those things into our lives is the best way to enjoy the blessings God has for us.

Biological Complexity in Living Organisms

Those who advocate for naturalistic evolution have a problem. Well, they have more than one, but this one is a math problem. In a publication on the National Institutes of Health’s Pub Med website, Alexei A. Sharov presents a dilemma for evolutionists. Simply stated, the size of the genome indicates biological complexity in living organisms, while macro-evolution requires exponential growth to achieve that biological complexity.

Perhaps this will be easier to understand if we relate it to Moore’s Law in semiconductor technology. In 1965, Gordon Moore of Fairchild Semiconductors and Intel projected that the number of components in each integrated circuit would double yearly. In 1975, the prediction was revised to every two years. It took on the quality of a “law” as the semiconductor industry used it as their target for planning production. Moore’s Law has led to technological changes that produced economic growth and social change. The point is that doubling the complexity of electronic technology means a logarithmic increase in versatility, as we have seen over the years.

Alexei Sharov applied that principle to evolution based on the exponential growth in biological complexity. Using the exponential increase in biological complexity in living organisms as a guide, it is possible to go backward in evolutionary time to see when life began. If the exponential hypothesis is true, tracing back in time, the origin of life would have been ten billion years ago. That is how long it would take for the genome to evolve to its present complexity in mammals. No evolutionist or other scientist believes our planet is that old. That presents a math problem for naturalistic evolution.

So, what do Sharov and others propose as the solution? They call it “panspermia,” meaning that life came to Earth from outer space. Nobel Prize winners Fred Hoyle and Francis Crick were advocates for panspermia. However, most evolutionary scientists reject it. Perhaps there is a better way to explain the fact that naturalistic evolution does not fit into Earth’s timeline. The solution, soundly rejected by Hoyle and Crick, is the idea of a Creator outside of time and space who designed the universe and life and put us on this planet for a purpose.

Afraid of the Facts

We should never be afraid of the facts when they are accurately presented. U.S. President John Adams said, “Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.”

Last week, we looked at James Tour’s challenge to the leading origin-of-life scientists. None of them were willing to address even one of the five roadblocks to abiogenesis that he presented. The fact is that the study of abiogenesis, the origin of life from non-living matter, has progressed very little in the last 70 years. Science has found many barriers to abiogenesis since the Miller-Urey experiment of the early 1950s.

Quora is a social media question-and-answer website where people post questions and others respond with answers. A recent questioner asked, “Are scientists terrified of abiogenesis?” A person who said he was “45 years a physician” answered that he was not afraid of abiogenesis. Part of the response from the “physician” was:

“Abiogenesis is a process that occurred at least once in the history of the earth, and that single event (or handful of events) may have left no traces at all. The steps in abiogenesis were probably a series of unknown physical and chemical steps. So, the process may never be known.”

Saying that “unknown physical and chemical steps” in a “process may never be known” is a vague answer. He seems to be saying, “I’m not going to worry about that because it scares me.” As I said, people should never be afraid of the facts.

Genesis chapter one uses the Hebrew word “bara,” which is always used to describe something that only God can do. Verse one describes God creating the heavens and Earth out of nothing. Verse 21 uses that word again to describe the creation of the first soulish animal life (nephesh). Between those verses, the term “made” (Hebrew “asah”) or the words “let there be” describe God’s work. Bara is not used again until verse 27 when God created humans.

Science has made significant progress in understanding the processes described by “made” and “let there be.” In some cases, scientists have even duplicated those processes in laboratories or particle accelerators. However, understanding how God created everything from nothing or life from non-living matter is beyond what science has accomplished or perhaps will ever understand. Christians should never be afraid of the facts because they point to a creator God.

World of Life Beneath the Soil

An unknown world of life lurks beneath our feet, and we should be thankful that it does. A research report in the Proceedings of the National Academy of Sciences (PNAS) says that approximately 59% of all living species on Earth live in the soil. Because there are so many organisms living there and they are generally out of sight, scientists don’t know how many species exist in the world of life beneath the soil.

According to the report by Diana Wall of Colorado State University, Fort Collins, soil organisms support life above the soil in many ways. They make it possible for us to grow food, and they break down organic waste. We often think of earthworms, but there are also many smaller worm species. We seldom see various insects that spend their lives in the soil. However, we do see insects that live much of their lives under the ground as well as above. Those include ants, springtails, woodlice, and millipedes. We often think of some animals that live in the soil as pests, such as termites and nematodes. However, they serve the purpose of breaking down organic materials, helping to keep the world from filling up with waste.

Plants also live in the world of life beneath the soil. For example, fungi do not use photosynthesis like green plants, so they can survive in the darkness. Subterranean life forms include the least familiar amphibians, the caecilians, whose name means “blind ones.” Naked mole-rats live underground, and many other mammals spend at least part of their lives in subterranean darkness.

According to the report in PNAS, “soil is the most biodiverse singular habitat.” We don’t often think of the world of life beneath the soil, but we should thank God that He thought of it. Subterranean life makes it possible for life above ground to thrive and prosper. We see this incredible web of life as evidence of design.

The Purpose for the Cosmos

Scientists and philosophers speculate on the question, “Why Is There Something Instead of Nothing?” The question is why our solar system exists and why there should be countless galaxies other than our Milky Way. Part of this question no one can answer, at least not at the present time. What is the purpose for the cosmos?

Is there intelligent life in any of the other solar systems? We can’t answer that question yet. However, if God’s purpose in creating the physical world in which we live is to advance the battle between good and evil, would He also do that in other places? Isaiah 55:8-9 challenges us to understand that God is not limited to our capacity to think and understand. In that passage, God says, “My thoughts are not your thoughts, neither are your ways my ways … For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.” Science fiction writers have created a whole industry on the assumption that the war between good and evil is ongoing and not limited to the planet on which we live.

A theologian may object to the possibility of other planets with intelligent life, saying, “So you think that Jesus died more than once and experienced more than one resurrection?” The answer to that is “no.” The biblical account is limited to planet Earth. However, many years ago, on a Larry King talk show with an atheist, a caller asked the atheist, “What would you do if a spaceship landed on the White House lawn and a little green man jumped out with a Bible in his hand and said, ‘Has Jesus been here yet?'” My atheist opponent smiled and said, “Punt.”

God may provide a different means for the battle between good and evil than what we see on planet Earth. The point is that there is a purpose for our existence and a purpose for the cosmos. God may use other places and methods to carry out that battle. On a cosmic level, the atheist has no purpose for existing.

Another point we must consider about why the universe exists is that all we see in the cosmos may simply be the result of the creation of time, space, and energy in the beginning. We now understand that the “big bang” singularity was not just a physical process. God created time and space, and matter-energy was engrained in the fabric of space. For us humans, limited to our five senses and able only to comprehend the changes in our physical world, the purpose for the cosmos is beyond our current understanding.

Recent advances in quantum mechanics have shown that time did have a beginning and that the fabric of space contains all the residual matter produced by the creation process. God was not just concerned about the scientifically ignorant population of the days of Moses and Christ. God knew that humans would eventually come to understand the creation process to such an extent that we could see evidence of God’s hand in the cosmos. As God’s ultimate creation, it makes sense that humans would seek to know the purpose for the cosmos.

We suggest that what makes humans unique and special is our spiritual makeup, being created in the image of God. Our physical qualities are of secondary importance. The whole message of the cosmos is that God is a God of incredible power, wisdom, and purpose. The universe radiates that, and the more we see of the creation, the more we understand of its Creator.

James Tour Challenge

How did non-living chemicals become living plants and animals? Origin of life research has been the focus of countless hours and vast expenditures by expert scientists for the last 70-plus years. The results have been, well, unremarkable. Chemist Dr. James Tour of Rice University issued a 60-day challenge. The James Tour challenge to the leading origin-of-life researchers called for them to show what progress they have made in 70 years.

Dr. Tour points out that there are five major hurdles that the origin-of-life scientists must clear. They are the fundamental problems that stand in the way of life originating from non-life (abiogenesis). In simplified form, they are:

Linking amino acids into chains
Linking nucleotides into RNA molecules
Linking simple sugars into chains
The origin of biological information
The assembly of all components into a cell

YouTubers are claiming that scientists have completely solved these obstacles to abiogenesis. If that is true, Tour challenged the leading origin-of-life researchers to verify and explain it. The James Tour challenge gave them 60 days to put up their evidence. Dr. Tour said if they could show that they have solved even one of those problems, he would shut up about the issue.

The James Tour 60-day challenge expired at the end of October 2023. Not one scientist could meet his challenge. In other words, in 70 years of research, no progress has been made on any of the major roadblocks to non-living matter becoming a primitive living cell.

If brilliant scientists with the best equipment and modern laboratories ever manage to produce life from basic elements, what will they prove? They will not show that life can originate by unguided accidents. They will have demonstrated that an intelligent being can create life from non-living matter. That is what the Bible has said for thousands of years.

Answering Today’s Challenges

The Church struggles to stay informed and relevant on the issues and answering today’s challenges. In October 2023, the Survey Center on American Life and the Associated Press/NORC released new data revealing the attitudes and beliefs of our friends and neighbors. If the Church is going to lead people to faith in God, we need to know what they believe. Jesus knew the teachings of Judaism and the beliefs of the Romans, and we must follow His example.

Here are some results of the recent surveys:

1) 44% of Americans have “hardly any confidence” in organized religion.

2) 29% of Americans believe evolution is the best explanation for the origin of life on Earth.

3) 38% believe humans and other living things have evolved over time due to processes guided by God or a higher power.

4) 31% believe humans and other living things have evolved over time, and God or a higher power had no role in this process.

5) 12% believe humans and other living things have existed in their present form since the beginning of time.

6) 49% believe scientists generally believe the universe was created in a single, violent event, often called the “Big Bang.”

The problem with surveys is that words like “evolution” are not defined. If “Naturalism” were used instead of “evolution,” the numbers would be different. Confusing “evolution” and “creation” is another source of problems with surveys. Evolution deals with the changes in things already created. It does not attempt to explain the creation of space, time, matter/energy, or anything spiritual.

It is interesting to see surveys like these and compare them to similar ones from past years. You don’t wear a hockey uniform to play baseball, and you can’t reach people today based on what people believed in the 20th century. God’s Word does not change and is a rock-solid guide for life, but young people today are radically different from last century. Answering today’s challenges requires meeting people where they are and not depending on methods that worked in the past.

How the Mpemba Effect Works

Yesterday, I warned of the danger of trying to solve an argument using the scientific method when people want to stick to their preconceived ideas. The argument I referred to was between my family members about whether hot or cold water freezes faster. The truth is that the phenomenon where hot water freezes faster is called the Mpemba effect after an African secondary school student who brought it to the attention of a British physicist. Even though it had been observed since Aristotle’s time, most people didn’t believe it, and nobody seriously attempted to explain how the Mpemba effect works.

Perhaps the reason science ignored the Mpemba effect is because it seems illogical and unreasonable. In 2013, Xi Zhang and colleagues at Nanyang Technical University in Singapore presented a possible solution to how the Mpemba effect works. Water molecules contain one atom of oxygen bonded to two atoms of hydrogen (H₂O). The oxygen atom shares an electron with each hydrogen atom in what is known as covalent bonding.

In addition to the covalent bonding within the water molecules, the separate molecules are held together by hydrogen bonds. Water molecules are polarized, and since water is a liquid, the molecules move around. When a hydrogen atom in one molecule is close to the oxygen atom in another molecule, hydrogen bonds loosely hold them together. Hydrogen bonds explain the surface tension of water, its relatively high boiling point, and how the Mpemba effect works.

As water is heated, the molecules move faster, stretching the hydrogen bonds, causing them to store energy, and allowing the covalent bonds to relax and give up some energy. Covalent bonds giving up energy is equivalent to cooling, allowing the heated water to freeze faster. In a 2017 issue of the Journal of Chemical Theory and Computation, Yunwen Tao and co-authors described using vibrational spectroscopy and modeling to show that hydrogen bonds can explain how the Mpemba effect works.

Other factors can be involved in water freezing to counter the Mpemba effect. Dissolved gases or other impurities, convection currents, evaporation, and even the container can influence the time it takes for water to freeze. The relative initial temperatures and consistency of the water samples are also critical factors.

The bottom line is that the design of water is an essential factor that makes life possible. We have said that before: HERE, HERE, HERE, HERE, and HERE. The fact that hot water can freeze faster than cold is hard to believe, but true. Even harder to believe is that the design of water, the universe, our planet, and life could be accidental, but atheists still argue that those designs all happened by chance. I challenge you to carefully consider where you stand on the existence of a creator God.
