The Tragic Fires of Lahaina

The tragic fires of Lahaina destroyed the train station — Lahaina train station before the fire

Those who have not been to Maui may be unable to comprehend the tragic fires of Lahaina and what happened there. I lectured on Maui several times, visited Lahaina, and even lived in the area for a short time in Kehei. Knowing the area, I can understand the conditions leading to the wildfire that destroyed the town and killed so many people.

Maui is a beautiful island. There are two huge mountains and two primary sections of the island. Haleakala is a popular tourist area with a road to Hana on the east side of a volcanic mountain where there are many gardens and lush vegetation. The other side is a barren area of relatively recent lava flows.

On the island’s northern side, a mountain area known as Kahakuloa has an observatory at the top. Lahaina is located on the west side of this mountain. I worked with a church on the east side of Haleakala, a wet area with lush vegetation. Between these two mountains is a relatively flat area with the villages of Waikapu and Pounene and the main shopping area for locals and tourists.

Unlike Haleakala, Kahakuloa has weathered igneous rock on its west side, which has led to soil capable of supporting crops, primarily sugar cane. When we were there, the growers used fire to remove the processed sugar cane. The area was very dry, with a vast cattle ranch and people living in open houses and sheds because rain was infrequent.

What we have described here is a classic example of a rain shadow. Moist air moves up the sides of the two mountains, and as it cools, it drops its water as rain. All the moisture is gone by the time it gets to the top of the mountains. As a result, very dry air goes over the mountain and cascades down the other side, creating desert-like conditions. This is not an area to attract tourists, but with irrigation, it’s a productive agricultural area.

A fire on the mountain’s east side would not spread since lush green trees and grass do not burn easily. On the mountain’s west side, any dead cane, grass, or bushes would be great tinder. People must plan for climate changes, avoiding towns where drought conditions can produce the tragic fires of Lahaina.

Agriculture must use places to plant crops based on understanding the movement of air and water. The tragic fires of Lahaina were not an act of God but the result of human mismanagement of what God has given us. The question is whether we will learn from our mistakes or repeat them.

The Problem of Homochirality

Can life arise spontaneously from non-living chemicals? Scientists have spent many hours and vast amounts of research money attempting to prove it can. One of the many challenges they must solve is the problem of homochirality.

All the large molecules required to make a living cell are composed of building blocks that have mirror images. When you look in a mirror, you see a reversed image of yourself. The right hand appears to be on the left and vice versa. The right- and left-hand analogy is used when referring to the building blocks of life. Those building blocks come in either right or left-handed forms. We call that handedness “chirality” from the Greek word for hand. Homochirality means having the same handedness.

Life almost exclusively uses only one chirality. The amino acids that make up proteins are left-handed. Scientists are uncertain why, but they have to accept the fact that to build the proteins that RNA and DNA molecules require for life, you must have only left-handed amino acids.

In nature, amino acids are not homochiral. They come in a distribution of about 50/50 left and right, creating the problem of homochirality. For amino acids to form the building blocks of life, they would have to be homochiral. Scientists have yet to find a way to make that happen, even in the laboratory. They aren’t even sure why life requires it since the chemical properties of mirror-imaged compounds are the same for all practical purposes.

The problem of homochirality is one of the many obstacles that prevent non-living chemicals from coming together to form life without intervention by an intelligent force. Even the intelligence of our best scientists has not overcome those obstacles. I saved an Associated Press news release from 2007 titled, “Scientists Believe Artificial Life Will Be Possible in 3 to 10 Years.” We are well past that goal, and I suspect they are not much closer today.

Purpose in the Evolutionary Process

Evolutionists such as Richard Dawkins tell us that life has no purpose and results from mindless, unguided evolution. That is the accepted doctrine of evolutionary biology. However, Dr. Gunter Bechly writing in the Evolution News website, reports on a review by Dr. Richard Buggs, giving some hope of at least one scientist finding purpose in the evolutionary process.

British plant biologist Richard Buggs wrote in Ecology & Evolution about a BBC science series called “Earth” in which the host, Dr. Chris Packham, made some very “non-Darwinian” statements suggesting purpose in the evolutionary process. Instead of viewing evolution as a natural process without purpose, Packham expresses it as an intentional process with direction.

Packham anthropomorphizes plants suggesting that they “have agency and intention.” He says they don’t “give up easily”; they “developed a new trick” and “were ready to start conquering the world.” He also points out something we have discussed on this site, that plants communicate with one another.

Packham finds purpose in the evolutionary process of plants. He suggests the greening of plants was not a purposeless, unintended process, but early photosynthesis was “something miraculous.” He describes the world as a “bountiful, blooming miracle” and the symbiosis between plants and fungi as “a match made in heaven.” The BBC promotes the series Packham hosts by saying, “Chris Packham tells the miraculous story of how plants turned Earth from a barren rock into a vibrant green world.”

In my graduate work at Notre Dame, an atheist taught our class on the historical development of planet Earth. He repeatedly pointed out that it takes enormous faith to believe that the complexities we see in Earth’s biological history leading to humans resulted from mindless chance processes. However, he justified his atheist faith by maintaining that given enough time, it could be possible.

Dr. Bechly concludes his article by saying he hopes this is “a new trend that would feel like a breath of fresh air amidst all the materialist and atheist propaganda in popular science media.” The current theories of how life developed on Earth by chance are so complicated and unlikely that evolution has become a faith for many. Finding purpose in the evolutionary process is a step toward recognizing that life is not an accident.

For over 50 years, we have said that evolution is a tool of God, designed to allow life to exist on a changing planet. God has indeed built into living things the capacity to change, so we have many varieties of dogs, cattle, grains, and fruit trees. Without this capacity for species to evolve and adapt, humans would have long ago run out of food.

With the verified climate changes in Earth’s history, many global mass extinctions would have occurred. There is a vast difference between the fact of evolution and the neo-Darwinian theories of naturalism and macro-evolution. Many conflicts would be eliminated if both sides could admit to that fact.

The Design of Mass Spawning

In Alaska, female moose have their calves at about the same time, so carnivores can’t eat them all, allowing enough survivors to maintain a healthy population. Many other animal species reproduce at the same time to overwhelm their predators. We see this survival method in the design of mass spawning of defenseless marine animals.

Palolo worms are an example of mass spawning. They live in tropical areas of the Pacific Ocean, including Samoa, Tonga, Fiji, Indonesia, Vanuatu, and some islands of the Philippines. These worms spend their lives hiding in the crevices and cavities of coral reefs. An interesting event takes place in Samoa seven days after the first full moon in October. The heads of the palolo worms remain in the coral reef, but their tails break off and swim to the surface by the millions. Those tails are filled with sperm and egg cells that are released into the ocean.

Because there are literally millions of palolo tails, and the release of sperm and eggs happens so quickly, the survival rate is very high. Other marine animals feast on them, and Samoans gather them using nets and buckets. Considering them a delicacy, the Samoans eat them raw or cooked in various dishes. Despite the consumption by humans and natural predators, there are so many palolos at once that their population survives. Their only real threat is loss of the coral reefs.

Another example of the design of mass spawning is the grunions off the coast of California and Mexico. Millions of female grunions ride a wave along the coast and lay their eggs on the beach. The next big wave brings the males who fertilize the eggs. The fertilized eggs remain in the tidal zone where sea birds and some other fish eat them, but the sheer numbers ensure the species continues.

The design of mass spawning indicates planning and coordination. Evolutionary chance models involve too many assumptions to be the best explanation. God has provided many systems that allow life to survive, and it is up to humans to protect the living system for future generations.

How Fast Are You Spinning?

You may think you are sitting still as you read this, but you are actually moving at tremendous speeds in various directions. You are on planet Earth which is rotating on its axis. The planet is also orbiting around the Sun. More than that, our solar system is spiraling around the Milky Way. Yes, the Milky Way is also moving in relation to other galaxies. It’s enough to make your head spin but let’s just look at Earth’s rotation. How fast are you spinning?

Earth’s circumference at the equator is about 24,900 miles, and a day, the time when Earth makes one rotation, is 24 hours. Therefore, if you are on the equator, you are moving at about 1040 miles per hour. Where I am, on the same latitude as Chicago, I am spinning around at 773 miles per hour. That’s because the circle at that latitude is much smaller. Those who live in Anchorage, Alaska, are moving at a leisurely 504 miles per hour. How fast are you spinning if you are standing on the North Pole? I doubt if any of our readers are doing that, but if so, you are just spinning in the same place like a top every 24 hours. Try not to get dizzy.

This spinning of Earth creates centrifugal force, which works against the pull of gravity. At Earth’s present rotational speed, if you moved to the equator from the North Pole, you would weigh about one pound less. Not a very efficient way to lose weight.

What would happen if Earth’s spin increased by one mile per hour? Centrifugal force would raise the ocean’s water level at the equator by a few inches and lower it in the Arctic Ocean. More noticeable would be that geosynchronous communications satellites would be out of their proper positions disrupting GPS services, satellite communications, television broadcasting, and military operations. A ten percent increase in Earth’s rotational speed would make the days only 22 hours long. And you thought you were having trouble getting everything done now. How fast are you spinning, and is the whole universe and our place in it just an accident?

What’s the point of all this? We have often discussed the many things that make this planet suitable for advanced life. Abundant water, a just-right tilt of the axis, the right spin, and a just-right Moon to stabilize the spin and speed. Those are only a few of Earth’s remarkable features. It almost seems that it was designed for a purpose by an intelligent Designer who knew we were coming.

Feathers – Complex Structures of Ingenuity

We take many things for granted without realizing the complexity of their design. That is undoubtedly true of bird feathers. American biologist Thor Hanson correctly wrote that feathers are “complex structures of ingenuity that defy the most advanced human technologies.”

Feathers are made of keratin, which is a protein. They are connected to blood vessels like our hair is connected to our vascular system. Once a feather reaches its final stage, it is disconnected from the blood vessel that has nourished it, reducing the weight of the feather. When molting occurs, and old feathers are discarded, the vascular system is re-connected by tiny muscles surrounding the feather follicles to grow a new feather.

These same muscles allow a bird to move its feathers for various purposes. Feathers serve the bird by providing insulation, waterproofing, color, display, and flight. Birds accomplish each of these functions in remarkable ways. Peacocks can present colorful displays, but so can parrots, pheasants, and various tropical birds.

Feathers provide insulation by trapping air, which is a poor conductor of heat. Down feathers trap air efficiently while adding very little weight to the bird. This same feature gives waterfowl their buoyancy while giving them insulation. Birds preen their feathers by treating them with oil from a gland just above the bird’s tail. The tight interlocking barbules in a bird’s outer feathers make them impenetrable to water. Birds use down to produce an environment that allows eggs to hatch and to keep chicks safe. Modern technology can’t match the heat-to-weight ratio of feathers.

Flight is possible because each wing feather has the shape of an airfoil to provide lift and minimize drag. Since the feathers are flexible, they can move to reduce drag, and their tips are designed to minimize turbulence making smooth flight possible. They really are complex structures of ingenuity.

Color in bird feathers is accomplished in several ways. For some feathers, melanin gives color to the feather’s keratin, and the structure of keratin is such that the bird’s diet can control its color. A flamingo’s pink color comes from eating algae that have carotenoids in it. Rather than using pigments, many brightly-colored bird feathers use structural color produced by manipulating light waves to create blues, greens, and iridescent colors.

Considering the complex structures of ingenuity we know as bird feathers brings to mind Psalms 9:1, “I will praise you, Lord, with all my heart; I will show forth all your marvelous works.” Feathers are among those marvelous works.

Ronald Numbers and Creationism

Dr. Ronald Numbers died on July 23, 2023, at 81. Numbers had an interesting journey from being a Seventh-Day Adventist to an agnostic and supporter of Darwinism. He is best known for his studies and books on Adventism, Creationism, and the history of science.

In 1976, Dr. Numbers wrote an excellent expose’ of Adventism titled Prophetess of Health: A Study of Ellen G. White. His study of the topic led to his leaving the Seventh-Day Adventist Church. This book remains an excellent source for those wanting to know the weaknesses of that denomination.

In 1992, Ronald Numbers wrote The Creationists: The Evolution of Scientific Creationism, a scholarly study of the history of the creationist movement. He revised it in 2006 with the subtitle changed from “Scientific Creationism” to “Intelligent Design.”

Although Ronald Numbers disagreed with the faith of the creationists he wrote about, he showed respect for them and presented factual history. Dr. Numbers was Hilldale and William Coleman Professor of the History of Science and Medicine at the University of Wisconsin from 1974 to 2013. Among other writings, he co-edited the eight-volume Cambridge History of Science.

In our exchanges with Dr. Numbers, he was always polite, interested, fair, and understanding. He had his own beliefs, some of which I disagreed with, but he strived for accuracy and fairness and set a model that the evolutionist and creationist camps should emulate.

Tell the Clouds What to Do

Yesterday, we asked the puzzling question, “How can clouds float in the air?” Clouds are made of water, which is heavier than air, so how can clouds float on air? The short answer is they don’t. We have two things to learn: the clouds are falling, and only God can tell the clouds what to do.

If you didn’t read yesterday’s post, I suggest you read it for background. But, for now, let’s return to where we left off in Job 38, where God speaks of clouds as He challenges Job and his friends. These are God’s words in verses 34-38:

“Can you lift up your voice to the clouds,
That an abundance of water may cover you?
Can you send out lightnings, that they may go,
And say to you, ‘Here we are!’?
Who has put wisdom in the mind?
Or who has given understanding to the heart?
Who can number the clouds by wisdom?
Or who can pour out the bottles of heaven,
When the dust hardens in clumps,
And the clods cling together?”

God asks Job if he can tell the clouds what to do, sending rain when the ground is dry. Of course, the answer is “No.” Human wisdom and understanding can’t do that, but God can. Before God spoke to him, Job seemed to believe that sometimes God used rain as a form of punishment (Job 37:13). God did withhold rain from Israel for years because of the evil leadership of Ahab and Jezebel, but Elijah’s prayer brought it back.

So does God make a practice of withholding rain as a punishment? Not according to Jesus. He told us to love our enemies, “that you may be sons of your Father in heaven, for He makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust” (Matthew 5:44-45).

We cannot tell the clouds what to do, whether we want it to rain or not rain. Only God can do that, but He is not a punishing old man in the sky ready to withhold rain or zap us with lightning if we misbehave. Many people have that confused idea, but the Bible does not support it. God sends sunshine and rain on the just and the unjust through the weather system He created. All weather conditions occur naturally according to God’s designed system, except in rare cases when He intervened with a timing miracle.

Let’s get back to our original question about clouds. They are water and sometimes ice, so how can they float in the air? The answer is that they don’t float. They are falling very gradually. Any unsupported object will fall to the ground because of Earth’s gravity. As it falls faster, the friction of the air molecules increases.

Any falling object will eventually reach terminal velocity when the friction force equals the pull of gravity. We can ignore the air friction for a bowling ball because it is minuscule compared to the ball’s weight. However, the weight of a water droplet in a cloud with a diameter measured in microns is minuscule, so the terminal velocity may be less than a hundred feet per hour. When you consider that clouds are thousands of feet in the air, that “falling” is too slow for us to notice. The water droplets may “dissolve” into the air before they fall very far. When they converge into larger droplets, they fall more quickly as rain.

The bottom line is, yes, the clouds are falling, but you will only notice it when they fall as rain. The more important point is that only God can tell the clouds what to do. The most important thing to remember is that God’s love sends sunshine and rain for everyone, even for those who refuse to recognize His existence.

How Can Clouds Float in the Air?

The sky is falling! Well, not exactly. Actually, the clouds are falling, or are they? Clouds are made of water, and everyone knows water is heavier than air, so how can clouds float in the air? Have you ever wondered about that? Are clouds floating, or is it an optical illusion? I’m baffled. How about you?

Before we answer those questions, here is another one. What does the Bible say about clouds? Clouds are mentioned many times in the Bible. God gives us a creation story in the Book of Job that expands on the Genesis account. These are some of the words God used to challenge Job and his friends in Job 38:8-9:

“Or who shut in the sea with doors,
When it burst forth and issued from the womb;
When I made the clouds its garment,
And thick darkness its swaddling band;
When I fixed My limit for it,
And set bars and doors;
When I said,
‘This far you may come, but no farther,
And here your proud waves must stop!”

In this poetic account, when the early Earth was a water world, God shut up the ocean “with doors” and told it, “Here your proud waves must stop!” I love that word picture of the creation process! God speaks, and the seas listen! But we are talking about clouds, and how can clouds float in the air?

In this Job passage, God explains something we wonder about in Genesis 1:1, where it says, “darkness was on the face of the deep.” The garment of clouds explains the darkness covering the oceans. Otherwise, we have to wonder why the first part of Genesis 1:1 tells us, “In the beginning, God created the heavens and the earth.” The heavens would have to include the Sun, Moon, and stars, as well as all of the galaxies and everything in them. Why, then, was there darkness on the water-covered Earth? God answers that question by saying: “I made the clouds its garment and thick darkness its swaddling band.”

Genesis tells us that God divided the water covering the land from the water in the sky, meaning the clouds. (See Genesis 1:9-10.) We read further in Genesis 1:14-18 that God caused the clouds to clear up enough to allow the Sun and Moon to be fully visible “for signs and seasons, and for days and years” and to “give light on the earth.”

We see that God’s description of the creation process in Job clarifies some questions that the Genesis creation account leaves unanswered. But that isn’t all God said about clouds in Job 38. He challenges Job with this question in verse 34:

“Can you lift up your voice to the clouds,
That an abundance of water may cover you?”

God verifies that clouds are made of water, and as Genesis tells us, God divided the water on the surface from the water in the air. So how did God make the water float in the air? Are the clouds defying gravity, or is this an optical illusion? Is God breaking His own laws of physics, or is He fooling us? The answer is – we are out of time for today. But tomorrow, we will answer the puzzling question, “How can clouds float in the air?”

Following the Rules of Debate

Recently media debates have occurred in discussions about climate change, global warming, fracking, abortion, evolution, vaccinations, immigration, and the existence of God. The problem with debates in the media generally is that they are not following the rules of debate.

Not too long ago, I had a radio debate with a talk show host in Pittsburg. I presented scientific evidence from cosmology showing that time and space came from God. From scientific data and probability, I then showed that design as the causal agent of creation in the natural world is more reasonable than chance theories. The talk show host admitted that he had not studied the evidence I presented and had no answer for it, nor did his listeners. With 30 seconds left in the program, he said, “I still don’t believe that the Bible’s teaching on morality makes any sense, and that proves that there is no God.” He then said he was an atheist, and I had not changed his mind. He signed off by claiming that, once again, he had won a debate with a Christian.

This is an example of not following the rules of debate, which is not confined to atheists and skeptics. The National Center for Science Education (NCSE) coined the term “Gish Gallop” to describe the techniques of the Institute for Creation Research, a creationist ministry using dispensational theology to promote their denominational beliefs.

Eugenie Scott of the NCSE describes Gish Gallop as: “dishing out a ton of information, accurate or not, that your opponent has no way to answer in the time available. It is an effective if ultimately shallow debate trick.” Scott goes on to say, “Debate is a sport. It is not a way of convincing an audience or the public of the accuracy of an opinion. It is played by rules that are different from those of logic and empirical evidence.”

A formal debate can be helpful when it has restrictions on what topics will be discussed and held between people with integrity who are following the rules of debate. We have quit doing debates because, in our experience, both atheists and creationist organizations cannot be trusted to allow reasonable discussion on the evidence. Be careful what you read in the media about viruses, climate change, the age of the Earth, etc., and make sure that statements and claims are well documented with reliable sources.
