Glacial Erratics and Time

People living in the southern United States may not be familiar with glacial erratics such as the one in the picture. Glacial erratics are rocks deposited by glaciers that are different from the native rocks in the area. Where we live in southwestern Michigan has many boulders like this. Many of us have at least one of them in our yard. They weigh hundreds or even thousands of pounds. Many years ago, when workers were digging the foundation for a wing of our local hospital, they hit a glacial erratic that was so large no equipment could lift it. They had to break it into smaller pieces to get it out of the way.

What is especially interesting about glacial erratics is that no two of them look alike, and they each have their own mineralogy. Some are a form of granite, some are metamorphic rocks like gneiss or schist, and some are sedimentary rocks like limestone or sandstone. As a public high school science teacher, I used to take my classes to the local gravel pit and have my students see how many different rocks they could find. Once, a girl found what she called “a pretty red rock.” I looked at it and recognized it immediately. It was a piece of jasper conglomerate, a rock only known to exist in an outcrop near Bruce Mines, Ontario – a place where I spent many summers as a teenager.

The question is, how did a piece of rock get from southern Ontario to northern Indiana? I have had students find pieces of pure copper in the gravel pit. There is a copper outcrop in the upper peninsula of Michigan that has the same color and texture as the ones my students found. In fact, almost every rock my students found came from a place far to the north of us where those rocks can be seen in outcrops. It is quite evident to thinking students that running water or wind did not carry those rocks. However, a moving sheet of ice can do it. Today you can go to an active glacier and watch that process taking place.

How long does it take for a sheet of ice to flow from Ontario to Indiana? There are places near Martinsville in southern Indiana where you can find similar glacial erratics. Glaciers bring not only minerals but water to our area. There are hundreds of lakes and ponds in the area where we live. Glaciers are a great tool of God to mold and shape the planet, and we are blessed by what glaciers have given us.
The glacial till we found contained no human remains or tools. The glaciers were there long before humans lived in Indiana. The process of shaping and molding the land took an enormous amount of time, but God created time, and it means nothing to Him. Only human theories and religions demand specific time elements. Truly “with the Lord, one day is as a thousand years and a thousand years as one day” (2 Peter 3:8).

Chemical Defense Against Predators

God’s design in the natural world provides protection for animals that would appear to be unable to defend themselves. Some animals can’t bite or run, and camouflage is not an option because their environment changes too quickly. Toads and frogs are classic examples of this, but they have an effective chemical defense against predators.

The Sonoran Desert toad (Incilius alvarius) in the desert southwest (also known as the Colorado River toad) defends itself with a chemical mix secreted through its skin. This toad is very large, and its desert environment makes hiding difficult. All toads secrete toxins through their skin, but the Sonoran Desert toad secretes a substance known as 5-MeO-DMT from glands behind each eye and on its legs. This chemical is a powerful hallucinogen secreted by no other toad or frog, and predators quickly learn to avoid it.

The giant leaf frog (Phyllomedusa bicolor) in South America (also known as the giant monkey frog) secretes a chemical known as kambo, which causes violent regurgitation and seizures and even affects the heart function of predators. The chemicals differ with each species, and researchers are trying to determine how the defenses work. Sonoran Desert toads and giant leaf frogs are geographically isolated, yet they share a common problem of vulnerability. They both use a chemical defense against predators but with different chemicals.

Interest in the Sonoran Desert Toad has increased because people have found that licking the toad produces a high. The psychedelic effect has caused people to catch the frogs, threatening their survival. Although predators are smart enough to leave them alone, apparently, humans are not. Abusers call the 5-MeO-DMT toxin “the God molecule,” but researchers warn that it can cause cardiac arrest.

Researchers are studying the ability of toads and frogs to secrete a chemical defense against predators. The difference in the chemicals depending on the species is still a mystery, but it’s a testimony to the design built into the natural world, allowing diversity in living things. The statement of God’s design of humans in Psalms 139:14 is also true of every creature in God’s creation.

Matter Greatly Exceeds Antimatter

It’s “one of the Universe’s best-kept secrets” and a mystery that physicists are working to resolve. Every subatomic particle in the universe has an antimatter equivalent. Each atom consists of electrons, protons, and neutrons. The negative electrons have alternative positrons with a positive charge. If you could combine an electron and a positron, they would cancel each other. Protons and neutrons, which compose the nucleus of atoms, are made of smaller particles called quarks. There are also anti-quarks, and if you combined a quark and an anti-quark, they would explode and destroy each other. Our universe, and us, can only exist because matter greatly exceeds antimatter.

If matter and antimatter were in a state of symmetry with equal amounts, they would have destroyed each other, and nothing would exist. Scientists theorize that the creation event, or Big Bang, should have created an equal amount of matter and antimatter, so they wonder why the lack of symmetry. In other words, why does anything exist in the universe, our planet, and our bodies? The universe is made of matter, while antimatter is almost non-existent except in radioactive particle decay and particle colliders such as the Large Hadron Collider (LHC) in Switzerland and France.

According to the Standard Model of particle physics, physicists theorize that a “charge-conjugation parity violation” (CP) caused the lack of symmetry – but how and why? Physicists working with the LHC say particles and antiparticles can spontaneously transform from one to the other. LHC spokesperson Chris Parkes said, “Through more precise measurement, large improvements have been made in our knowledge. These are key parameters that aid our search for unknown effects from beyond our current theory.”

We can be thankful that in today’s universe, the amount of matter greatly exceeds antimatter. Since physicists are looking for an explanation, they may eventually solve the mystery. It will be interesting to see the scientific explanation for the lack of symmetry. Whatever process scientists discover, we suggest that this is another example where intelligence and wisdom provide a more reasonable ultimate explanation than accidental chance offers.

The Cosmological Argument for God

Cosmology provides strong evidence for God’s existence. The basic cosmological argument for God involves three simple questions:

1) Was there a beginning to time, space, and matter/energy? The evidence says there was.

2) Was the beginning caused or uncaused? Taking the position it was uncaused violates scientific conservation laws.

3) If it was caused, what or who was the causer? The evidence is that the cause can not be blind, mechanistic chance. Logic suggests that the cause was an intelligence, in other words, God.

As more data becomes available to support intelligence as the cause of planet Earth, the cosmological argument for God becomes stronger. If we define life as that which can breathe, move, respond to outside stimuli, and reproduce, what is necessary for life to exist? Astronomers now talk about the habitable zone (HZ) of stars. This is the zone around stars where the temperature on a planet would allow water to exist in the liquid state on the surface.

Recent discoveries have shown that M-class dwarf stars are the most common and longest-lived stars. The problem with these stars is that their HZ is very close to the star, so tidal forces would lock the rotation of any planet so its same side would always face the parent star. One side of the planet would be constantly hot while the other would be cold. Also, M-class stars would bombard these planets with stellar flares causing massive radiation levels that would eliminate any possibility of life. Other star types create various problems for a life-supporting planet.

Astronomers have determined there is a galactic habitable zone (GHZ) in addition to the star’s habitable zone. A star must be far from the galactic center to have a planet with life on it. The high star density near the core of a galaxy exposes the star system to deadly supernovae and gamma-ray bursts. Mass distribution within a galaxy is also an issue because, near the galaxy’s core, mass concentrations cause gravitational instability.

The basic cosmological argument for God is now supported by a vast number of parameters that must be within precise limits to allow life to exist in a planetary system. Having a large moon is essential to the survival of life on a planet. Likewise, having a shield against incoming cosmic bodies is critical. A body the size of Comet Hale Bopp hitting planet Earth would have sterilized it, killing even microbes that might be present. The Earth’s shield is the arrangement of the Jovian planets. Jupiter, Saturn, Uranus, and Neptune preventing objects like Hale Bopp from reaching Earth.

The more we look at the cosmos, the unique qualities of our planet reinforce the cosmological argument for God. Proverbs 8 personifies Wisdom speaking of God’s creative power and design. As we learn more about the cosmos, the stronger the evidence becomes that “in the beginning God created the heavens and the earth” (Genesis 1:1).

Predictions of Earth’s Demise Are Highly Exaggerated

With many world issues to be concerned about, politicians and the media are predicting the end of the Earth because of global warming. Yes, climate change is real, but predictions of Earth’s demise are highly exaggerated.

U.S. Representative Alexandria Ocasio-Cortez received widespread media coverage as she predicted the end of humanity would happen within 12 years. Politicians today continue to scream that the end of the Earth is near. The media quoted our current administration with these words: “The world is facing a grave emergency…Every week brings new climate-related devastation. Floods. Drought. Heat waves. Wildfires, Superstorms … We are in a battle for our lives … Climate change is the biggest threat to the global economy.”

There is no question that we need to take steps to improve our planet, but predictions of Earth’s demise are highly exaggerated. The prophets of doom are not only inaccurate, but they are unsettling. Consider the following facts which you won’t see in most of the media:

1. The number of hurricanes annually making landfall in the U.S. has declined since 1900. That is also true for major hurricanes – category three and above. The second-lowest recorded year was 2022.
2. The wildfires in Australia in 2019 and 2020 were close to Sydney and Melbourne, where the major news organizations are, so the coverage was exaggerated. The total number of fires in Australia as a whole was one of the lowest levels on record. The amount of burned areas over the entire planet has dramatically declined over the past 25 years.
3. In the 1920s, roughly 500,000 people died annually due to climate. That number has been dropping to approximately 11,000 people in 2022.
4. In 1890, renewable sources produced 94% of the world’s energy (mostly wood). In 2021, 16% of the world’s energy was from renewable sources.
5. Unlike the politicians’ proposal of net zero by 2050, the most optimistic model suggests we could reach 95%. However, the cost would be roughly $11,000 per person per year.
6. Yale climate economist William Nordhaus received the Nobel Prize in economics in 2018 for his studies comparing the cost of climate change and climate policy. He showed that restricting the average world temperature to a 6.75 degrees Fahrenheit rise, instead of the 7.4 degrees that it will rise if we do nothing, would cost 20 trillion dollars. Limiting the increase to 5.3 degrees would cost about 100 trillion dollars.

The bottom line is that the media and the politicians are exaggerating the long-term effects of climate change and underestimating the economic cost of climate policy. Motivating people to do something is good, but we must consider the cost and apply innovation to do the job efficiently.

God created a resilient Earth, and we must recognize the challenges and be good stewards of God’s gifts. All the hand-wringing of the media and the politicians accomplishes very little. Predictions of Earth’s demise are highly exaggerated.

Freeing Up Nitrogen Atoms

Nitrogen is an essential ingredient in biological molecules, such as proteins and DNA, but nitrogen must be in a free state for these molecules to form. By that, we mean nitrogen atoms that are not already bonded to each other, making them inert. Seventy-eight percent of our atmosphere consists of nitrogen, but nitrogen atoms in the air are bonded with other nitrogen atoms to form nitrogen molecules that are chemically inert. It takes enormous amounts of energy to tear apart nitrogen molecules, freeing up nitrogen atoms to bond with other elements.

A nitrogen atom can be useful for life when it bonds with three oxygen atoms to make nitrate. Nitrogen can also bond with three hydrogen atoms making ammonia, which is also useful for life. This is a complicated issue because Earth’s early atmosphere did not contain much oxygen, so the rock record shows nitrogen bonded to hydrogen atoms. Ammonia has a very low gram molecular weight, so it can escape Earth’s gravity. We see large amounts of ammonia in the atmospheres of our Jovian planets, but that is because their large masses provide enough gravity to hold on to the ammonia.

Humans create nitrogen fertilizer through chemical and electrical processes. But that method of freeing up nitrogen atoms is complex and requires a lot of energy. Scientists in the past have theorized that microbes could have been the method of nitrogen fixation, reducing the nitrogen to nitrates. This is a “chicken-egg” problem because nitrates had to be in existence for the microbes to exist. Freeing up nitrogen atoms would require some non-biologic processes. Studies have shown that electric discharges in lightning have enough energy to tear apart nitrogen molecules, but the rate is insufficient to account for all the nitrogen needed.

New research on volcanoes has shown that eruptions release oxygen and supply enough energy to tear apart nitrogen molecules that bond with oxygen. The nitrates produced would accumulate, allowing life to survive. Studies have shown that a strong volcanic eruption can produce about 60 million tons of nitrate. In 2022 the Tonga-Hunga Ha’apai volcano in Indonesia produced 400,000 discharges in one day.

As we learn more about the chemistry and physics required for freeing up nitrogen to allow life to exist on this planet, the complexity and design of the system astound many researchers. The Bible merely says God did it, but not how or what complexities were involved. Everywhere we look, we see that a wounder-working hand has gone before. Nitrogen is an excellent example of how much wisdom, power, and planning was required for a life-bearing planet to come into existence.

Tardigrades Have Incredible Resilience

NASA’s “Astronomy Picture of the Day” for May 21, 2023, shows a small creature called a tardigrade crawling on some moss. The picture is an electron micrograph of the tardigrade, which is a millimeter long (0.0393701 inches). Most tardigrades range between 0.3 and 0.5 mm. They eat plants and bacteria and help convert them to other forms essential to molding and shaping the environment. In addition, tardigrades have incredible resilience to adverse conditions.

Tardigrades can go for decades without food or water. They can withstand temperatures near absolute zero but can also survive in boiling water. They can survive in pressures well above what has been measured on the ocean floor or even in a near-perfect vacuum. Tardigrades have incredible resilience, allowing them to survive direct exposure to high radiation levels. They can repair their own DNA or reduce their body water content to a few percent.

They were first described in 1773 by a German zoologist who called them “little water bears.” Then, in 1777, an Italian biologist gave them the “tardigrade” name, which means “slow walker.” These creatures remind us that living things too small to see with normal human vision are major movers and shapers of higher life forms.
The formation of unseen life systems that allow us to exist demonstrates life’s complexity. It demands an acceptance of the fact that we are not just a chance collision of atoms. The more we see of life and design in the creation, the more we comprehend the magnitude of the Creator’s power and wisdom.

Convergent Evolution and Carcinization

When unrelated species of animals or plants have common features, evolutionary biologists call it “convergent evolution.” There are many examples, such as:
* Dolphins and bats use echolocation to find food.
* Titan arum and rafflesia plants use putrid odor to attract pollinators.
* Nightingales and humpback whales sing similar songs just for beauty.

Those are only a few of the vast number of examples that scientists explain as convergent evolution. You can probably think of others. For example, bats, birds, and insects all have wings, but they are not related. In addition, unrelated venomous or poisonous creatures often wear bright colors as a warning, for example, snakes, frogs, and insects. Usually, the convergent features of various animals and plants serve an obvious purpose for the species’ survival.

Perhaps the most repeated convergence appears in the crab-like body shape. A crab has a flat, rounded shell and a tail that tucks under its body. Evolutionary biologists say that body plan has “evolved” at least five times. Scientists even have a name for this phenomenon. They call it “carcinization,” but they can only guess why it happened.

The result of carcinization is that many unrelated crustaceans resemble crabs. As a result, we often call them crabs even though they are not true crabs. A familiar example is the so-called king crab. Crab-shaped animals come in a wide range of sizes and live in various habitats, from the oceans to the mountains. So, with these creatures living in diverse ecosystems, scientists have difficulty explaining why they evolved the same body plan. Some suggestions include the tucked-under tail providing greater safety from predators or the body shape allowing them to move sideways.

We have a suggestion of why the crab shape, or carcinization, shows up in so many different crustaceans. Rather than convergent evolution, the common traits can be explained by a common Creator. That would explain why these creatures have the DNA building blocks for crabbiness – oops, I mean crab body shape.

Chondrite Meteorites from Space

What are the odds of you getting hit by a rock that came to the Earth from Mars? A New Jersey woman named Suzy Kop walked into an empty bedroom in her house and found a hole in her ceiling and a still-warm six-inch potato-shaped rock on the floor. Scientists studying it have concluded it is one of the rare stony chondrite meteorites, dating back to the beginning of the solar system.

The word “chondrite” comes from the Greek “chondres,” meaning sand grain. Such rocks from space contain tiny, millimeter-sized granules, iron and nickel alloys, and as much as 50% silicate minerals. There are several different kinds of meteorites. Some are called “irons” because they are almost entirely made of iron and nickel alloys. Others, called “stoney irons,” have silicate minerals in addition to iron and nickel alloys. In addition, carbonaceous chondrite meteorites contain water, sulfur, and even some organic material.

In their excavations of ancient cities, archaeologists have found knives and various other objects made of meteoric iron material. Ling before humans learned how to smelt iron to make tools and weapons, they found iron meteorites and pounded them into useful tools. (See “Metal From the Heavens” in National Geographic for June 2023, pages 102-104.) Genesis 4:22 refers to Tubal-Cain, a son of Lamech, “who forged all kinds of tools out of bronze and iron.” However, early humans used iron meteorites long before Tubal-Cain forged tools.

The question of why there are different kinds of meteorites is of greater interest. The answer is that the meteorites came from the formation of different objects in various places in the cosmos. Scientists believe iron meteorites came from the cores of asteroids or planets where extreme heat would allow only resistant metals to exist. Silicate minerals were probably ejected from planets with less heat and lower pressure. Some stoney chondrite meteorites have the same chemical composition as Mars, so they probably came from that planet.

In 2018 the Japanese Hayabusa2 spacecraft brought back samples from the asteroid Ryugu. The samples contained uracil, which is a building block of RNA. Some astronomers believe a planet exploded and that many meteorites, as well as Ryugu are what remain from that explosion.

Researchers are sampling other asteroids, but the message is that space is full of the remains of God’s creative actions. Likewise, the existence of planet Earth and the life on it tells us that this is indeed a unique place that we need to care for and preserve.

The Careless Use of Chemicals to Control Pests

One of the significant challenges we face is dealing with biological pests. In the United States, the accepted pest control method is using chemicals to kill anything that affects crop growing, spreads diseases, or just annoys us. We use weed and vegetation killers, insect sprays, chemical treatments for trees, and chemicals for the soil to make our lives more comfortable and increase the food supply. Unfortunately, the problems caused by the careless use of chemicals to control pests become more evident as we see the collateral damage and the cost of chemical production and distribution.

The current battle over the potential cancer-causing effect of Roundup reminds us of the health damage Agent Orange caused for military personnel in Vietnam. On a personal note, my younger brother died from the effects of Agent Orange that he was exposed to during his military service. We need to realize that God has given us tools to control negative environmental influences without the careless use of chemicals.

Studies show that the collateral damage from air pollution and ground-level ozone includes increased heart disease, diabetes, obesity, and dementia. Even aggression among animals and humans increases when pollution levels rise. For example, a study of 70,000 U.S. cases showed more people were bitten by dogs on smoggy days.

American foulbrood is a bacterial disease that has wiped out many broods of honey bees and is apparently catalyzed by pesticides used on crops that bees pollinate. The U.S. Department of Agriculture has approved an oral honeybee vaccine against the disease. But, again, this is an example of collateral damage from the careless use of chemicals to control pests.

Natural pest control avoids collateral damage. For example, vineyard owners near Cape Town, South Africa, use a group of domesticated Indian runner ducks to eat the snails and bugs that infect their vines. In addition to eating the pests, the ducks leave natural fertilizer to nourish the vines.

People use bats to eat insect pests in various places worldwide. Locust swarms are not an issue where bat populations are large. Insecticides can cause the death of songbirds, and as the bird populations decline, insect swarms increase, creating more problems. Even removing fish and frog populations harms pest control, as fish and frogs eat many insects and their larvae.

God has built pest controls into our planet, but humans often upset the balance. Restoring natural controls is within our reach, but people often believe the careless use of chemicals to control pests is easier and more profitable. Unfortunately, ignoring God’s design leads to health problems linked to the chemicals we dump on our land and into our rivers, lakes, and oceans.
