No Life Without Water

Without water, life would not be possible. For that reason, astronomers are constantly looking for other locations in the universe where liquid water might exist. Only in such places could there be any hope of finding life. Whether life exists anywhere in the universe outside of planet Earth is a question people have asked for hundreds of years. Scientists still don’t know the answer, but everyone agrees that there could be no life without water.

The water molecule seems very simple. It is H²O–one oxygen atom combined with two hydrogen atoms. However, instead of bonding in a straight line (H-O-H), the two hydrogen atoms are on one side of the water molecule at a 104.5-degree angle from each other. That alignment gives the hydrogen side of the water molecule a partial positive charge, while the other side has a partial negative charge. Because of that, the positive and negative sides of water molecules attract one another and form hydrogen bonds resulting in a network of water molecules.

When water is in the gaseous state, the interaction between molecules is negligible. However, when it is in the solid form of ice, each water molecule forms a bond with four others, creating a lattice that causes ice to be lighter than liquid water. For most substances, the solid state is heavier than the liquid state. This unique property of water causes ice to float. Additionally, the low thermal conductivity of ice prevents the water below from freezing. If lakes and oceans froze from the bottom up, it would kill all marine life and ultimately all life on Earth.

If water molecules did not form hydrogen bonds, instead of boiling at 100 degrees C, water would boil at -100 degrees C. That would prevent life processes. Furthermore, because there is a 100 degree C difference between water’s melting and boiling points, life is possible in Earth’s wide range of environments. Water has the highest heat of evaporation of any known substance so that it remains liquid up to and even at its boiling point. It also has the second-highest heat capacity of any known substance, allowing its temperature to remain stable during heat fluctuations in the environment. Those qualities of water are also critical for life, meaning that there could be no life without water.

Water’s ability as a solvent makes it essential for the life processes of living cells. Likewise, water’s inability to dissolve oily substances is vital to create a strong “hydophobic effect.” Cell membranes, DNA, RNA, and proteins all contain oil-like regions. If the water in the cells could dissolve them, life would not be possible. In addition, the water molecule can participate in and enable chemical processes such as hydrolysis, reduction, oxidation, and others that are essential in living cells.

The bottom line is that there is no life without water and the fine-tuning of the hydrogen bonding in water molecules. With new scientific discoveries, we see fine-tuning for life in the cosmos and even in the cells of our bodies. Without that fine-tuning, life would not exist, and we would not be here. Accidental coincidences do not explain such incredible precision of design. We think the explanation goes beyond science and points to an intelligent Designer.

For much more on this, read chapter three, “The Chemical Anthropic Principle,” in Fazale Rana’s book Fit for a Purpose.

Changing Climate and the Human Response

There is no question that we are experiencing a rapidly changing climate. The data is massive and comes from many places on Earth. There hasn’t been much of a change here in Michigan so far. We have had a very typical winter at the time of this writing. However, in places like Alaska, the changes have been very pronounced. Many areas around the globe have witnessed changes not seen before in modern times.

We must understand that there have been many periods of changing climate throughout Earth’s history. At one time, glaciers covered a significant part of North America, giving undeniable evidence of a frigid climate. Around 12,000 years ago, there was a cold period scientists call the “Younger Dryas.” Many large animals went extinct during that climate change. When dinosaurs roamed the Earth, the climate was very different from today. Not only was it warmer, but the oxygen level was higher.

The point is that changing climate is not new. Our planet is a dynamic place, and climate change is part of its history. The issue is how much humans contribute to climate change and whether it will have disastrous consequences for us. As the planet warms, the thawing of glaciers and polar ice releases water into the ocean. This means we have to prepare for weather changes and a rise in sea level.

Some people will use the changes to deny God’s existence. Others will blame God or claim that He is using climate change as a weapon to afflict us for rejecting HIm. Instead, we suggest that God has allowed us to understand how the creation works and expects us to use that knowledge to prepare for the future.

Perhaps as humans battle with the changing climate, it will prevent the nonsense of humans battling other humans. God won’t force solutions on us, but He has given us the tools we need to live successfully on this planet.

The Carbon Miracle and Life

Life on Earth would not be possible without carbon. All known living things are carbon-based, and there is a good reason for that. Carbon is the fourth most abundant element in the universe, and it’s also plentiful in Earth’s crust. That means there is plenty of it to form life. It’s the second most abundant element in the human body, after oxygen. However, that abundance is a carbon miracle because it demonstrates precise fine-tuning of the cosmic creation event known as the big bang.

First, let’s look at the qualities of carbon that make it so useful for life. Carbon can form more compounds than any other element. That’s because it is the smallest element that has four valence electrons. As we said in our discussion of oxygen, all atoms look for eight electrons to complete their valence shell. Carbon can form covalent bonds by sharing electrons with up to four other atoms to complete that shell.

Furthermore, the energy required to make or break those bonds is at the exact level to build large and complex molecules with both the stability and reactivity necessary for life. Carbon atoms are also lighter because they are smaller than the other atoms with four valence electrons. Their small and lightweight qualities allow enzymes to manipulate the organic molecules formed around carbon atoms. Metabolism requires the manipulation of organic molecules.

Carbon can combine with other carbon atoms to form macromolecules that life requires. Without carbon, there would be no proteins or DNA. Because of its unique qualities, carbon can form hydrocarbons such as sugar, lipids, and alcohols for storing energy in living organisms. Without carbon, there could be no life functions such as breathing, digestion, excretion, or reproduction. In other words, there could be no life. Some scientists have suggested the possibility of silicon-based life somewhere in the universe. However, there are numerous problems with the “rock people” concept, and there is no evidence to support it.

But what is the carbon miracle? According to Fermilab, it is “miraculous” that carbon exists. The cosmic creation event known as the big bang formed only the elements hydrogen, helium, and lithium. Clouds of hydrogen and helium gas came together because of gravity to form stars that collapsed and became hot enough to fuse some pairs of helium nuclei with two protons each into beryllium with four protons. The next step would be to fuse one more helium nucleus to form carbon with its six protons.

That is where there seemed to be a roadblock. The beryllium isotope is so unstable that it decays back into two helium atoms in a ten-thousandth of a trillionth of a second. However, scientists found that the carbon nucleus has an “internally excited short-lived state” that allows the miraculous microsecond bonding to take place. According to scientists, as reported by Fermilab, “Amazingly, if the strength of the nuclear force between protons and neutrons after the Big Bang were different by less than 1%, carbon would be extremely rare, and the universe would be devoid of life.”

That is the carbon miracle, and we don’t think it was an accident that the creation event was fine-tuned. English astronomer Sir Fred Hoyle first suggested the unique quality of the carbon nucleus that made it possible for carbon to come into existence. Hoyle was an agnostic, but seeing the fine-tuning of the creation, he wrote, “A common sense interpretation of the facts suggests that a superintellect has monkeyed with physics, as well as with chemistry and biology, and that there are no blind forces worth speaking about in nature. The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question.” (Fred Hoyle, “The Universe: Past and Present Reflections”) We believe that “superintellect” is God.

The Whole Earth Sings

One of the fun units in physics is the study of vibrations and resonance. A simple demonstration of sympathetic vibration is an apparatus that consists of a tuning fork mounted on a wooden box. If you place near it a second box with a tuning fork of the same frequency, you can hear the effect called “resonance” or “sympathetic vibration.” Striking the tuning fork on one box will cause the tuning fork on the second box to start “singing” without being touched. A second tuning fork with a different vibration frequency will not respond. The amazing thing is that the whole earth sings.

When building a guitar or violin, a craftsman has to be very careful not to allow any part of the instrument’s box to naturally vibrate at the same frequency as the strings. If it does, that frequency will be louder than all other frequencies, and the sound will be distorted.

This effect is not confined to tuning forks and musical instruments. Resonance is all around us and in us. For example, your inner ear has hairs of varying lengths and thicknesses, resulting in specific vibration frequencies. If a sound at that frequency reaches your ear, the hair will vibrate and signal the brain to identify the pitch. Not having some of those hairs produces tone-deafness.

Taking a fine glass goblet and running a moistened finger around the edge will produce a tone at a specific frequency. That is the natural frequency of the goblet. You can produce a sound at the resonant frequency of a glass that will cause it to shatter, but probably not with any human voice.

Amazingly, researchers have found that everything in the natural world has a resonant frequency. For example, recent research on the Matterhorn near Zermatt, Switzerland, shows that it vibrates with a resonant frequency. The mountain actually vibrates about once every two seconds (.42 cycles per second.). Our ears hear sound frequencies between about 20 and 20,000 cycles per second, so we need instruments to detect the Matterhorn’s frequency.

You could say that the whole earth sings. Interestingly, the Bible refers to mountains, and even stars, singing. (See Isaiah 44:23, 49:13 and Job 38:7). Isaiah and Job certainly didn’t understand their statements to refer to mountain resonance. However, our understanding of what happens in nature gives new meaning to this poetry describing how the whole earth sings praise to God.

Oxygen and Nitrogen Levels in the Atmosphere

Oxygen and nitrogen are two of a handful of elemental superstars of life. Without them, life would not be possible. In some ways, these two elements are very similar, but they are also very different.

Oxygen and nitrogen atoms differ in only one proton and one electron. In chemical reactions, the important subatomic particle is the electron, and oxygen has eight while nitrogen has seven. In the last two days, we talked about the difference that one electron makes. Oxygen and nitrogen make up about 99% of our atmosphere, with nitrogen composing nearly three-quarters of our air. So why is nitrogen’s percentage so high compared to oxygen?

As we said previously, the triple bond of a nitrogen molecule requires more than twice as much energy to break as the double bond of an oxygen molecule. The oxygen bond can be broken to allow combustion oxidation and energize our bodies. On the other hand, the nitrogen bond is not easy to break, but plants require nitrogen for photosynthesis and growth. What is the solution?

Lightning breaks the nitrogen bond allowing rain to wash nitrogen to the ground. Plants such as beans, peas, and alfalfa, which we call legumes, have microorganisms on their roots that extract nitrogen from the air. That enriches the soil with nitrogen while providing for the legumes. More than a century ago, scientists found a way to extract nitrogen from the air to produce ammonia. That process enabled fertilizer production, which today allows farmers to produce enough food for the world’s population.

It is not easy to break the nitrogen bond so it can combine with other elements, but with 78% of the atmosphere being nitrogen, there is no shortage. So why is our atmosphere mostly nitrogen? Since it is only about 21% oxygen, wouldn’t it be better to have more oxygen so we could breathe easier? The answer is that nitrogen stability is essential for our safety. Wildfires have been a significant problem in recent years. If the atmosphere consisted of a very high percentage of oxygen, fires would be more common and dangerous. If the atmosphere consisted of 100% oxygen, all it would take is one lightning strike to set the whole planet on fire.

Remarkably, we have the correct percentage of elements in our atmosphere. We have the right amount of oxygen to allow respiration to power our bodies and combustion to power our vehicles and industry and heat our homes. At the same time, we have the right amount of nitrogen to prevent uncontrolled combustion leading to the destruction of life. We have just a small amount of carbon dioxide, which plants need for photosynthesis. Plants use CO² and generate oxygen to keep the gases in balance. The balance is amazingly precise as long as humans don’t generate enough carbon dioxide to mess it up.

During the dinosaur age, the oxygen level was higher, on the order of around one-third of the atmosphere. That allowed the enormous animals to prepare the Earth for humans. Now we have the precise balance to sustain human life and advanced society. The question is, did the features of oxygen and nitrogen and the balance between them happen by accident, or was it part of an intelligent plan? We think the best explanation is that an intelligent Planner of life created it.

The Atmosphere Is Fine-Tuned for Life

Nitrogen and oxygen together make up about 99% of the air we breathe. The vast majority of our atmosphere is nitrogen. Oxygen is ten times as abundant as nitrogen in the universe, but it makes up only about 21 percent of our atmosphere. So, the less common element is the most abundant in our atmosphere. What does that mean to us? The bottom line is that the atmosphere is fine-tuned for life. Let’s examine that more carefully.

An atom of oxygen and an atom of nitrogen differ by only one proton and one electron. That may not seem like much, but it makes a world of difference. Both of those elements form diatomic molecules, meaning that two atoms bond together to make one molecule of oxygen or nitrogen.

Covalent bonding is the chemical bonding of atoms by equal sharing of electrons. That bond gives atoms stability in their outer, or valence, electron shells. Atomic stability requires eight valence electrons. The only elements with that number are the so-called “noble gases”–helium, neon, argon, krypton, and radon. For that reason, they are inert, refusing to combine with other elements. All other elements need electrons to complete the octet in their valence shells.

An oxygen atom has six electrons in its valence shell, so it needs to share two electrons to become stable. When an oxygen atom shares two electrons with another oxygen atom, they both become stable. Nitrogen, on the other hand, has only five valence electrons. Therefore, by forming a covalent bond with another nitrogen atom, sharing three electrons, both atoms complete their outer shell. In this way, our atmosphere is made up of stable diatomic oxygen and nitrogen molecules.

However, not all molecules are equally stable. That is where we see the atmosphere is fine-tuned for life. For example, oxygen molecules have a double bond sharing two electrons, but nitrogen atoms have a triple bond sharing three electrons for more stability. That difference may seem insignificant, but it is essential to make life possible. Come back tomorrow when we will explain what a difference it makes.

Life Under the Antarctic Ice Shelf

One of the amazing things about our planet is its ability to support life. We find a diversity of living things on land, in the air, and under the oceans. Scientists have even found a variety of life under the Antarctic Ice Shelf.

Gerhard Kuhn and Raphael Gromig of Germany’s Alfred Wegener Institute, a polar and marine research organization, drilled through the Antarctic ice shelf. After boring through 656 feet (200 m) of ice, they scooped up material from the seafloor another 328 feet (100 m) down. What they brought up surprised them. They turned the material over to David Barnes, a marine biologist with the British Antarctic Survey. He was so amazed that he said, “Is this a practical joke?”

Barnes was surprised that as he studied the sediment, he identified 77 different species of animal life in the material they extracted from a single drill hole. The species identified included bryozoans, which are stationary filter feeders, and tube-feeding worms. Barnes said, “This discovery of so much life living in these extreme conditions is a complete surprise…”

Filter-feeders feed on algae which require sunlight to grow. However, there is no sunlight to provide photosynthetic life under the Antarctic ice shelf. The explanation is that these creatures are feasting on microorganisms that the ocean currents sweep under the ice shelf. You could say the food is delivered to their doorstep.

Despite the cold and dark conditions, life survives in a location where fires, storms, or predators do not threaten it. The only thing that may threaten these creatures is the melting and breakup of the ice shelves. So, here in one of Earth’s least-known habitats, life survives. Like the scientists who discovered and studied these life forms, we are amazed. But, more than that, we thank God for wisely creating life with the ability to adapt and survive even in hostile environments.

Evolution Is Not Creation

An error shared by some creationists and some evolutionists is confusing evolution with creation. One problem is that the terms “creation” and “evolution” do not mean the same thing to different people. Regardless of how we use the terms, evolution is not creation. Evolution and creation are two completely different subjects that are only very remotely related.

We see the concept of creation in the very first verse of Genesis 1. “Reshith Elohim bara shamayim erets” is the Hebrew of this verse. Each of these words has great significance:

“Reshith” tells us that there was a beginning to time, space, and matter-energy. Our studies in quantum physics continue to support that statement.

“Elohim” is a plural word for God and conveys the power and nature of the agent that produced the beginning.

“Bara” is a word used only in reference to God and implies a process beyond human capacity to reproduce.

“Shamayim” refers to “heaved up things,” meaning the expanding universe.

“Erets” refers to our functional planet. It is used 648 times in the Old Testament.

A person might deny God as the causal agent of time, space, and matter-energy. Nevertheless, the creation’s characteristics strongly suggest intelligence and wisdom. However, this entire subject has very little to do with evolution. “Evolution” means “unfolding change.” The evolutionist starts with the assumption that not only time, space, and matter-energy existed, but that they existed in a form that allowed change to take place.

Many evolutionary scientists bring into their thinking the question of God’s role in shaping what He had already created. The other option is naturalistic evolution which attributes all we see in the natural world to chance. But, regardless of how you define the terms, realize that evolution is not creation.

For some interesting points on this topic from the perspective of a scientist who is a Christian, we suggest “How might God have Guided Evolution? Scientific and Theological Viewpoints” by Dr. Peter Bussey. It was published in the June 2021 issue of the Journal of the American Scientific Affiliation. Dr. Bussey is Emeritus Reader in Physics with the University of Glasgow in Scotland and works with the European Organization for Nuclear Research (CERN) and its Large Hadron Collider (LHC), the world’s largest particle accelerator.

A Larger Dinosaur Has Been Found

We are amazed by the enormous size of animals in the distant past. From a giant millipede to the Titanoboa and the Titanosaur, the size of ancient animals excites fossil hunters. Since 2017, Patagotitan has held the record for the largest dinosaur at 120 feet (36.5 m) long and weighing over 57 tons. However, paleontologists in Argentina recently found pieces of a larger dinosaur.

The size of this animal has several implications. First, we need to be reminded that, unlike mammals, reptiles never stop growing, so there is virtually no limit to their size. A more significant issue is having environments warm enough for such animals to live and enough plant material to sustain them, plus a high oxygen level.

The environment that allowed a larger dinosaur to survive would not have been hospitable to mammals. Reptiles can not only survive very hot conditions, but they require heat to sustain their bulk. A hot Earth with very wet conditions would also promote rapid plant growth. Accordingly, the plant fossils from the time of those animals indicate huge size and rapid growth.

The Bible makes clear that everything humans would need to live on Earth was produced before humans were created. Therefore, we have maintained that God was not a magician miraculously zapping things into existence. God could do the creation any way He wished, but He wisely chose to make the resources humans would need in such a way that we could find them.

God acted as an engineer, producing the coal, gas, oil, iron, salt, and other resources we would need by processes we can study and understand. The volume of fossil fuels stored up for our use is a staggering number. Present-day processes on Earth could never produce them, but the enormous animals and plants of the past created enough resources to take us into the nuclear/solar age.

The Bible tells us that God created planet Earth, not how or how long He took to do it. Genesis 1:1 is not dated or timed. However, as we look at the record of the past, we see God’s wisdom and power and the magnitude of the creative process that allows us to exist.

Rather than trying to fit a larger dinosaur into Noah’s Ark, we need to take Genesis for what it says and not add denominational traditions. We must not use the economy of language in Genesis to justify our human religious theories.

A Giant Millipede and What It Teaches Us

Can you imagine a giant millipede almost nine feet long? Most of us have seen inch-long millipedes under a rock or in a rotting log. Like centipedes, millipedes get their name from their many legs. “Mille” means thousand, and “ped” means foot, so a millipede could have a thousand feet.

Some 10,000 species of millipedes live today, and they are related to lobsters, shrimp, and crayfish. Australian researchers recently announced finding a three-inch-long millipede with 1,306 legs, which stirred up great interest among biologists. But that is nothing compared to a new fossil discovery.

Now researchers from the University of Cambridge have found the fossil of a true giant millipede in England. This specimen is 8.6 feet long and would have weighed about 110 pounds. Named Arthropleura, this is the largest invertebrate ever found, replacing giant sea scorpions that previously held the record. This animal lived before the dinosaurs and was an omnivore eating plants, nuts, seeds, and other invertebrates.

The importance of a find like this giant millipede is that it tells us that large animals, insects, and plants existed in the past. In addition, it reminds us that the ecology of the early Earth, as it was being prepared for later life forms, was very different from what we see today. At that time, England was a tropical area where massive quantities of resources like coal, limestone, and various minerals were being produced. Therefore, the plant and animal life in that ecology had to be large.

The Bible does not describe all of the processes because even today, we have a hard time comprehending how that ancient world functioned. Genesis 1:1 simply tells us that God created the Earth, not how or when or what processes He used to prepare the planet for humans. But because God used a process, we can locate resources far underground. If He had simply “zapped” the planet into existence, we would have no clue about where to look for oil or coal or various minerals.

Proverbs 8 talks about the wisdom that allowed the production of all we see and use today. When we hear about a find like this giant millipede, it underlines how carefully God planned for our existence. Today, our challenge is to take care of the planet by preserving what God has given us rather than wasting it.
