Canyonlands Field Trip Purpose

Canyonlands Field Trip

Today is the final day of the 2018 DOES GOD EXIST? Canyonlands Tour. The pictures are of Bryce Canyon and Alan Doty who has served as a guide along with John Clayton. They have been making these educational tours for several years. The purpose of the Canyonlands field trip is not just entertainment. We want to help people understand the history of how God has crafted the Earth He created to make it a suitable home for people. We also want to show that science and faith are friends, not enemies. This video is from an earlier journey to the Canyonlands. We share it here so that John can tell you why he believes these trips are important.

You can watch the video series John mentions by using THIS LINK.
We also invite you to see our two previous posts about the Canyonlands Field Trip HERE and HERE.

Grand Canyon Formation

Grand Canyon Formation
As we told you before, this is the week of the 2018 Canyonlands Tour. We mentioned the plaque at the Grand Canyon watchtower with the verse from Psalms. Today, we would like to share with you a video segment from a previous field trip to the Grand Canyon. In the video, geologist and teacher John Clayton uses the diagram shown above as he describes the layers of the Canyon and the various processes that formed them. The Grand Canyon formation processes are complex and involve God’s work through natural forces over a vast span of time.

Canyonlands Tour 2018

Canyonlands Tour 2018

This week John Clayton is with a group of people on what we call the Canyonlands Tour. Many times over the years John has taken groups of people to visit the Grand Canyon, Bryce Canyon, and Zion Canyon, as well as other locations in northern Arizona and southern Utah.

The Canyonlands Tour is not just a sightseeing trip. It’s an opportunity for Christians to learn about how God has worked to create those “natural wonders.” John uses his knowledge of geology to explain the many interesting and beautiful features of the “canyonlands” area. Some people try to explain the Grand Canyon by “flood geology.” John explains what the real science of geology actually tells us about the formation of that remarkable Canyon.

With the assistance of Alan Doty who has hiked the canyons many times, the Canyonlands Tour is always an interesting and educational experience. One of the places on the agenda is the “desert view” area overlooking the Canyon. That is the location of a watchtower which visitors can tour.

On a level of the tower, there is a wall which has a plaque attached as you can see in the picture. The plaque contains the words from Psalm 66:4. It says, “All the earth worships Thee; they sing praises to Thee, sing praises to Thy name.” That plaque has been there for years. With atheists demanding the removal of any acknowledgment of God on public property, perhaps the only reason those words are still there is that some might interpret the “Thee” and “Thy” as referring to the Grand Canyon.

However, those pronouns do not refer to the Canyon, but to the One who created it. The process of creating the Canyon was no small feat. It did not happen in one flood. The people on the Canyonlands Tour will learn something about the processes that science still does not fully understand. In the meantime, there are those who say the Grand Canyon disproves God. It does not. It only invalidates a false interpretation of the Bible which many have adopted.

It’s too bad the people who placed that plaque didn’t include verse 3 as well. It says, “Say to God, ‘How awesome are your deeds! So great is your power that your enemies cringe before you'” (NIV). I am sure that there have been some atheists who have cringed when they read the words of that plaque. I suspect that sometime an “offended” atheist will demand its removal. However, nobody can remove the Grand Canyon and the testimony it gives to the power and glory of God.

Fragile Lunar Temperature

Fragile Lunar Temperature
When astronauts landed on the Moon in the 1970s, they left several instruments behind that continued to send data to the Earth. Among those instruments was a set of temperature probes bored into the surface that measured how heat travels through the lunar soil. The data from those instruments indicate a fragile lunar temperature.

Scientists had assumed that heat flows out from the Moon’s core, just as it does on Earth. The question was how fast it was flowing and was this due to residual heat in the core of the Moon or due to radioactive decay inside the Moon. They were amazed to discover that heat was flowing into the Moon instead of out of it.

Later measurements showed that the heat flow into the Moon only happened where the astronauts had been walking and where the rover drove. Scientists now agree that the footprints of the astronauts and the tracks of the rover compressed the lunar sediment which darkened the print. Sunlight was absorbed more efficiently in the darkened areas. Thus it was the absorption of sunlight which caused the elevated temperatures in the borehole and made it appear that it was a lunar feature. A detailed treatment of this research appeared in the Journal of Geophysical Research: Planets in May of 2018.

We are only beginning to understand how delicate the creation process is. The fragile lunar temperature indicates that a small variation can alter the end product of the process. God’s creation of the cosmos demanded incredible knowledge of all this and continues to sustain it today.

Our increase in knowledge further emphasizes the wonder expressed by David in Psalms 8:3-6: “When I consider your heavens, the work of your fingers, the moon and the stars, which you have ordained, what is man, that thou art mindful of him, and the son of man, that you visit him. For you have made him a little lower than the angels, and have crowned him with glory and honor. You made him to have dominion over the works of thy hands; you have put all things under his feet.”

Evolution Does Not Explain Creation

Evidence from Cosmology
The notion of God as the creator has escaped our world today. We have not understood that there was a beginning, that God caused the beginning, and that His imprint is on all we see around us. We have been told that evolution explains all these things, but in reality, evolution doesn’t address the question. Evolution does not explain creation.

Evolution assumes that time has been created. Evolution assumes that space has been created and that matter/energy has been created within space/time. Evolution assumes that forces we are just beginning to understand shaped the matter/energy in space/ time so that stable physical matter came into existence. It assumes that the properties of matter/energy caused it to become organized into galaxies, and stars, and solar systems.

Evolution further assumes that within one of those solar systems a planet was created within the Goldilocks zone where water could exist as a liquid. On that planet, carbon and oxygen and heavy metals were produced to allow tangible matter to exist for long periods of time. Then evolution assumes that within a limited time these materials came into existence in an environment and with a catalyst that could produce life.

Once all those assumptions have been made, evolution attempts to explain how that first life changed to eventually become us. In other words, evolution tries to explain how once the creation happened, things got to be as they are today. Evolution does not explain creation.

God’s Elevator — The Vortex

God's Elevator — The Vortex
One of my favorite demonstrations as a physics teacher was to put a student on a frictionless stool and spin them around with their legs extended out in front of them. I would then tell them to pull in their legs. When they did that, their angular velocity increased dramatically—they spun faster. We see this when a spinning figure skater pulls in their arms and legs causing a dramatic increase in their rotational speed. This is an excellent demonstration of the conservation of energy and angular momentum. It is also a design feature that enables a wide variety of living things to fly without prohibitive losses of metabolic energy. We call it God’s elevator.

Instead of solids, what happens if the material that is spinning is a fluid – water or air for example. When water goes down the drain in your sink, it picks up speed as it gets near the center. In the very center, there won’t be any motion at all. In a hurricane, warm air is rising in the center, and as air rushes in to replace the rising air, it increases in speed. The center with no air rushing in is the eye of the hurricane, and the maximum velocity is in the wall near the eye.

A less dramatic example of the vortex is the convection cell on a hot summer day. The Sun heats the ground which then heats the air near the ground. The heated air rises, and as it does, the edges of the air are cooled by contact with the colder air around it. This creates a doughnut-shaped thermal vortex that rises to make an invisible, energy-saving elevator for any organism that can get into the doughnut. What this means is that an animal like a hawk does not have to beat its wings and spend enormous energy to soar to a high elevation. This is a huge saving in metabolic energy. An amazing number of living organisms use God’s elevator to get high into the sky and travel very long distances.

Charles Darwin, while sailing on the Beagle, noticed a mass of spiderlings 60 miles off the South American coast. These organisms are terrestrial creatures, but they were able to travel enormous distances by using vortices. Moths use vortices to make journeys from where they are to new areas.

Recent studies of birds have shown that the wings of a bird create a vortex system which is like a ladder. There is almost no lift produced by the bird’s wings on their upstroke, but the downstroke creates a vortex. That vortex combines with vortices on the wing tips making a ring. The combination of these ring vortices makes a zigzagging ladder-like system which lifts the bird. This allows the bird to use a smaller amount of energy than if it merely powered itself through the air. That is why the birds in your backyard fly in a zigzag pattern rather than a smooth path.

Blackfly larvae that live on the bottom of a stream position themselves so that water flowing over the bottom of the tube-shaped larva goes faster creating a low pressure rising along their bodies. The resulting vortex brings up food particles along the floor of the stream to the filters that extend out the top of the larva. The number of examples of living things that use vortices to feed or to conserve energy as they travel seems to be endless.

How do these animals know to use the vortex effect? The way they position themselves and how they use the vortices in their environment works to their advantage. God’s elevator is a great testimony to His wisdom of design in the creation. We can know there is a God through the things He has made and how they use things like vortices to survive (Romans 1:20).

Why So Much Stuff in Space?

Why So Much Stuff in Space?
One of the questions people ask about God’s creation is why so much stuff in space? If humans are the focus of God’s creation, why did He create so many planets, galaxies, and stars? If God’s purpose was to have the human race as the battlefield for the struggle between good and evil, surely He didn’t need to create 100 billion other stars in our galaxy and billions of other galaxies.

There are so many assumptions involved in this question that it would take many more pages to explore them all. First, this question assumes that God’s creation of life only happened here. It assumes that there are no other planets anywhere in the creation that have sentient beings living on them. You can argue that forever, but the Bible doesn’t give an answer. The Bible only describes Earth because it presents a message for our planet and its people.

The question also assumes that God only intended for us to live on the surface of this planet. I get letters regularly from people who suggest that we have no business going into outer space because God intends for us to live here and nowhere else. That is a massive assumption, and one that I suggest is misguided. One recent discovery has given another possible answer to why so much stuff in space. Humans are rapidly exploiting the mineral wealth of planet Earth. We know that the Earth contains a finite amount of iron, nickel, cobalt. If we should survive on Earth for much longer than the 21st century, we are going to run out of resources.

Japan’s robotic spacecraft Hayabusa 2 visited asteroid 162173 Ryugu (pictured) in June of 2018. Data from the spacecraft indicates that this asteroid is composed almost entirely of nickel and iron. The spacecraft was returning a sample to Earth for analysis. This asteroid is one kilometer wide, and at the current market value, the iron and nickel in the asteroid are worth over 80 billion dollars. God’s plan for us may be far greater and longer than we realize. Space contains a wealth of mineral resources. God has provided for us in many ways, and we always seem to have just enough of a resource to get us to the next source. We had just enough wood to get us to hydrocarbons, and just enough hydrocarbons to bring us to nuclear and solar power.

Our problem is not resources. Our problem is being able to get along with each other well enough to avoid destroying ourselves. Jesus Christ has the answer to that major issue, but the size of the cosmos merely reflects God’s power and wisdom. As we wonder why so much stuff in space, we have to think of the words of the psalmist, “What is man, that you are mindful of him? And the son of man, that you visit him? For you have made him a little lower than the angels, and have crowned him with glory and honor. You made him to have dominion over the works of your hands; you put all things under his feet” (Psalms 8:4-6).

Why Are Plants Green?

Why Are Plants Green?
Why are plants green? The answer to this is some pretty basic physics.

The colors of light that we receive from the Sun have different energies. Red is the lowest of these energies followed by yellow, green, and blue. The sunlight with the highest energy that actually reaches the surface of the Earth is green. Blue light, which is more energetic, is refracted away by Earth’s atmosphere and scattered as it interacts with molecules in our upper atmosphere. That’s why the sky is blue.

When you look at an object, the color you see is the color reflected by that object. A red ball is red because it reflects red and absorbs all other colors. A green leaf is green because it reflects green and absorbs all other colors. If the highest energy of light reaching the surface of the Earth is green, and if the leaf reflects green, what does this do for the leaf? The answer should be pretty obvious – it keeps the leaf from absorbing too much energy and getting cooked. In the fall of the year when the leaves lose their chlorophyll A, which gives them the green color, what happens? The leaf gets cooked, falls off the tree, and we have to scrape it off the yard.

If a planet had a different atmosphere so that a different energy of light reached its surface, its plants would have to be a different color. To quote Kermit the Frog “It’s not easy being green.” Why are plants green? They are green because green is essential to life on Earth.

This explanation is greatly oversimplified. Obviously, not all plants have green leaves. Some plants live under a canopy of other trees and have to use a different system. The design of life on Earth is incredible, and the green trees and grass around us testify to the wisdom of God in making a place for life to exist.

We have a children’s book titled Why Is the Sky Blue, Why Is the Grass Green. You can read it and all of our children’s books on our Grandpa John’s Science Club site using THIS LINK.

Is there Anything God Can’t Do?

Is there Anything God Can't Do?
This October will mark 50 years that I have been doing question/answer sessions in lectureships and answering written questions in correspondence courses and online. One of the favorite questions from skeptics and atheists has to do with what God can or cannot do. Is there anything God can’t do?

If you say that there is something God cannot do, you have a direct conflict with numerous passages in the Bible that indicate nothing is impossible for God. If you say there is nothing God can’t do, you get a response like, “Can God create a rock so big He can’t move it?” There are all kinds of fun responses to that question. Marshall Keeble once said, “Yep, and He can create a bulldozer big enough to do the job.” Marshall was being funny and not proposing a serious answer. Theologians have constructed all kinds of elaborate arguments to respond to the question such as saying God cannot lie etc. The problem, however, is in a fundamental error in understanding.

My favorite analogy offered seriously is to ask the skeptic to draw me a four-sided triangle. It should be evident that the question is flawed. A triangle by definition has three angles and is subtended by three sides. In a Euclidean universe, a four-sided triangle cannot exist. A rock, by definition according to Webster is a mass of stone. If a mass of stone gets too large, it assumes a different name – asteroid, continent, planet, etc. Since God created the cosmos including planetary-sized masses of rock, the question reflects the ignorance of the person who asked the question.

If there were such a thing as a four-sided triangle, God could create it, but we have to throw out the question because it makes no sense to us. The same is true of a stone so big God can’t move it. Is there Anything God Can’t Do? That question is a way of avoiding the truth of what God has done.

I have many people who write me and say, “I don’t want anything to do with the church.” The obvious weasel word here is “church.” Webster has the primary definition of church as a place of worship. The biblical concept of church is very different. It refers to those who are called out of the world – people not a building. Jesus told Peter that He would build His church on what Peter had confessed—that Jesus was the Christ, the Son of the living God. There was no building at that time, nor during the lifetime of the apostles. We don’t try to defend what human-created structures and organizations do. No serious person would reject the church the Bible describes if they really understood it.

Blaming California Wildfires on God

Blaming California Wildfires on God
I am writing this article near Redding, California. We have been involved in lectureships in California during this month of August 2018. The fires that are burning in this state have been a constant source of inconvenience for us. They are a major tragedy for people here who have lost homes, businesses, and health. Smoke makes travel difficult, but for people with respiratory problems, the smoke can be lethal. Over and over we have heard references to “why did God do this to us” or in other cases “thank God for…” While we understand the emotions that go with all that is happening, we need to stop blaming California wildfires on God.

While working in California, we are blessed to be with Keith Crummer. Keith has been an ecosystem manager and forest management expert in California for over 30 years. He has degrees in forest management from the University of California at Berkeley and from Oregon State. As we discussed the incredible damage of this current series of fires, Crummer just shook his head in sadness. He told us that what is happening in California was caused by human ignorance and mismanagement.

One fact that astounded me is that there are more trees in the United States now than have ever existed in the history of this area. Before the white man arrived on the scene, trees grew and died just as they do today. When the biomass accumulated on the forest floor, small fires set by lightning or by spontaneous combustion eliminated it. Those fires wiped out small trees and allowed grasses to flourish which in turn supported deer, elk, and other mammals. That made the forest less dense. While fires existed, they were small fires that ran out of fuel very quickly.

Then humans moved in and stopped the fires and allowed vast amounts of biomass to accumulate on the forest floor. The trees became so dense that grass could not grow. Crummer said that scientists know that managing the forest involves harvesting the material that falls to the forest floor, thinning the trees, and using the energy that is available from them. This would eliminate the potential for uncontrolled burning because massive amounts of fuel would not be available. It would also allow animals like deer and elk to proliferate. The current fire catastrophe is 100% due to the mismanagement of the environment by people who thought they were doing the right thing by eliminating fires and refusing to allow cutting down trees or removing brush.

In the Genesis account, God told the first humans to “…fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of heaven and over every living thing that moves on the earth” ( Genesis 1:28-30). “The Lord God took man and put him in the garden to work it and keep it…” (Genesis 2:15-16).

God did not tell them to merely preserve the creation. The creation is a living, changing, dynamic entity. It is our job to facilitate the changing Earth. Working and keeping the Earth means to control those things that would destroy what God created including the animals that live on it. We need to stop blaming California wildfires on God. After the fires in Yellowstone National Park, the elk and deer populations returned to levels close to what they were before humans arrived. If we had done what God commanded in Genesis and worked the forests of the western states, the fires today would not be spreading as they are.

So God did not “do it” to those who lost homes. We understand the anguish and desperation that our friends have experienced, but instead of blaming California wildfires on God we need to realize that politicians and bureaucrats have mismanaged the wonderful resources God has given us. Environmental extremists need to understand more fully what must be done to preserve and protect the environment for the benefit of future generations. Followers of Jesus Christ need to let those who are suffering know that we want to help them. God is not the cause of their burden, but He wants to send His people to love and support those who are suffering.
