Do We Really Want to Move to Mars?

Mars is our closest neighboring planet at 33.9 million miles (54.6 million km), and it seems that various countries want to send people there. Several countries have launched successful missions to fly by, orbit, or land on the red planet, but none have yet sent people there. The list includes the United States, the Soviet Union, Japan, the United Kingdom, India, Russia, the United Arab Emirates, and China. As for human explorers, Elon Musk of SpaceX once expressed a desire to send people there in 2024—an overly ambitious objective. The UAE wants to establish a colony there in the next 100 years—a much more conservative goal. The question is, “Do we really want to move to Mars?”

Why does Earth seem to be designed for life while Mars is a rocky and barren place without an atmosphere? Scientists theorize that at one time, Mars had an atmosphere but then lost 99% of it. Why? Mars is smaller than Earth, so it has less gravity to hold onto the atmosphere, but that’s only part of the answer. One hypothesis is that solar wind (charged particles from the Sun) tore away the atmosphere. Then why didn’t Earth lose its atmosphere since we are even closer to the Sun? Earth’s magnetic field protected our planet. Why do we have a magnetic field? The movement of Earth’s molten iron core generates the magnetic field.

Many other factors make planet Earth ideal for life, and importantly, advanced life. So do we really want to move to Mars? The now-defunct Mars One project got tens of millions of dollars from thousands of people who signed up for a one-way trip to Mars to establish a human colony there. Elon Musk has indicated that he wants to get people to Mars just for the sake of getting there. He was quoted as saying, “Fundamentally, the future is vastly more exciting and interesting if we are a space-faring civilization and a multi-planet species…”

With all of this desire to leave the planet ideally designed for life, the question we should ask is, “Was Earth’s design merely chance happenstance, or was it part of a divine design?” I suggest that the many factors that make our planet just-right for human life indicate more than chance coincidence.

Physician-Assisted Death

One of the facts of life is that eventually, we will all die. Many of us have seen people endure enormous pain over a long period before death finally came. I am thankful that my wife Phyllis and my son Tim did not go through months of intense pain before passing on. Medical science has made great progress in extending life but has not been as effective in relieving pain. That is part of the reason we have seen a movement for legalizing physician-assisted death.

New Jersey passed a “Medical Aid-in-Dying” law two years ago, and last year 33 terminally ill people in the state ended their lives. Since 2016, California has had “The End of Life Option Act.” New York has a “Good Death” Act moving through the legislative process. The movement to legalize physician-assisted death is not confined to America. Holland was perhaps the pioneer of physician-assisted death in Europe. Columbia became the leader in South America back in 1997. The “Colombian Pain Institute” administers euthanasia for “intense physical or mental suffering due to an injury or incurable illness.”

The Week magazine for October 22, 2021 (page 8) carried a report demonstrating the difficulty of legalizing physician-assisted death. In Colombia, a 51-year-old woman named Martha Sepulveda has ALS and was scheduled to be euthanized. She would be the first person in Colombia to receive physician-assisted death without a terminal prognosis. However, the Colombian Pain Institute concluded that “her condition had improved” so she is no longer qualified for the procedure. Now she has a lawyer fighting for her right to die because she “is not willing to continue to live.”

Christians have concerns in this matter. In 1 Corinthians 3:16, we read that our body is “the temple of God and that the Spirit of God dwells in us.” The next verse tells us not to defile the temple. This concept is continued in 1 Corinthians 6:15-20, which teaches why a Christian should not be involved in prostitution. In ancient times, death came more quickly than in today’s world with modern medicines. Therefore, a person near death today deserves special attention and Christian compassion. In Proverbs 31:6-7, we read, “Give strong drink to those who are ready to perish, and wine to those who are of heavy hearts.” When David was near death, he was chilled, and a woman came to warm him not for sexual purposes but to relieve his discomfort. (See 1 Kings 1: 1-4).

The doctors I know are horrified at the prospect of deciding to end someone’s life. It is hard to assess the collateral damage of someone saying, “I choose to die rather than blessing others, especially my family.” In many cases, financial concerns are a significant motivation for ending life, and there are horror stories of involuntary euthanasia in Holland. Christians should lead the charge to develop medical steps to relieve suffering and pain. Financial problems should not be an issue in a wealthy country like the United States.

From an atheist’s viewpoint, death is the end, and physician-assisted death is merely the solution to suffering. However, I continue to be reminded of my son’s last words to me before he died. He said, “Dad, I am going to see Mom, and I will actually be able to see her and be with Jesus.” These words were from a blind, mentally challenged, COVID-ravaged young man who had battled muscular dystrophy, cerebral palsy, and schizophrenia all of his life. He was ready to move on to something better.

Tim Clayton’s story was told by John N. Clayton in the book Timothy: My Son and My Teacher available HERE.

The organization Compassion and Choices has been a leader in the movement to legalize physician-assisted euthanasia.

God Has the Solution for Problems Humans Cause

When humans mess things up, God has the solution for problems humans cause. Since 2014, kelp forests and starfish have virtually disappeared from Alaska to Mexico. Sunflower sea stars were the main predators for sea urchins. The sea stars were severely affected by pollution, exploitation of marine resources, agricultural runoff, and climate change. Now scientists say they are functionally extinct. Since the sunflower sea stars are gone, the sea urchins have multiplied out of control.

Northern California has lost 95% of its kelp forests. The problem is that sea urchins are herbivores, and they eat the lower stems of kelp, causing the plants to die. Because of that, Fish, abalone, and various other marine animals that depend on the kelp forests have died. In many places, spiky sea urchins now carpet the seafloor, and locals have called those areas “urchin barrens.”

A partial solution to this problem is the sea otter, a keystone species and a major natural predator of sea urchins. Sea otters have a very high metabolism to keep them warm in the cold water, and it makes them ravenous consumers of sea urchins. In a single day, a sea otter can eat 25% of its body weight in food.

Researchers at the University of California, Santa Cruz, have found that sea otters are eating three times as many urchins as in 2014. In areas where sea otters are active, the kelp beds are starting to return. Once again, God has the solution for problems humans cause.

Role of Elephants in Desert Survival

There are many natural situations where, to a casual observer, an animal or plant appears to be a useless consumer of resources. As conservationists try to solicit funds to protect elephants, others say those animals have no useful function. Elephants consume vegetation which can cause hardships in periods of drought. However, as scientists study the role of elephants in desert survival, the need for these animals has become increasingly understood.

Savannah elephants live in eastern and southern Africa, with the highest densities in Botswana, Tanzania, Zimbabwe, Kenya, Zambia, and South Africa. In those regions, termites build huge mounds, and they bring a large number of elements and compounds to the surface as they dig. Eventually, the mounds flatten, creating depressions that fill with water during the rainy season. At that time, elephants come and dig up the nutrients they need as they wallow in the mud. They leave the area coated with soil which they carry away, leaving a deeper depression that eventually becomes a large water hole.

In addition to enlarging the water hole, the elephants deposit massive amounts of dung. The dung contains plant seeds that grow to become the start of vegetation around the water hole. That vegetation brings insects which, in turn, bring birds. Wading birds carry in fish eggs, bringing a wide variety of life to what was a desert. The oasis this process produces is critically essential to animal and plant life and humans.

The role of elephants in desert survival in Africa makes preserving them a key to the survival of all life in the region. Elephants have unique properties critical to the success of this system. Matriarch elephants remember where previous water holes were and lead their group back to dig and enlarge those holes, eventually making it an oasis. Some plants are correlated to bloom and provide seeds at the proper time for other forms of life. If the water hole dries up, some fish, amphibians, and reptiles can burrow into the soil and survive for up to five years, waiting for the next rain.

Earth’s design automatically produces all kinds of ecosystems, including deserts. God has designed life to adapt and exist, even in extreme environments, and the role of elephants in desert survival is a great example.

Are We in a Matrix or Base Reality?

When speaking on evidence for the existence of God, John Clayton often begins by saying that first, you must believe that you exist. He says, “If you don’t believe that you exist, you have more problems than I want to deal with.” Some people today are suggesting that we do not exist in reality. The question we need to consider is, “Are we in a matrix or base reality?” Let’s examine what that means.

Philosophers have often contemplated the question of whether there is any reality. A philosophy professor I once learned from said that some of his associates begin their philosophy class by suggesting to their students that nothing is real, including the walls of the lecture hall. However, he pointed out that the professor always exits through the doorway at the end of the lecture. Are the walls real? Is anything real? Are we in a matrix or a base reality?

In 1999, there was a movie titled The Matrix in which people were made to believe that they lived in a surreal world where they could have superhuman powers and face life-threatening dangers while all the time being strapped to a chair with electrodes connected to their bodies. The idea must have found a sympathetic audience because it spawned three sequels, with a fourth scheduled for next month.

Now, some scientists are suggesting that we are in a simulation. According to one analysis, the chances that we are living in a “base reality” (meaning not a simulation) are about 50-50, with a slight edge to base reality. So people from scientists such as Neil deGrasse Tyson to entrepreneurs such as Elon Musk have suggested that we could be merely characters in a massive video game. To further that concept, we have quantum theory with its “spooky action at a distance” (Einstein’s quote), such as quantum entanglement and superposition.

In 1948, American mathematician Claude Shannon introduced the concept of the bit as a basic unit of information. Computers work with bits, which can have a value of either 0 or 1. By combining millions, billions, or trillions of bits, we can perform complex calculations and create sounds, images, or even videos. That is how modern cameras, televisions, telephones, and computers work. So the question is, “If the universe is a giant computer simulation, a matrix rather than base reality, how many bits would it take to create the simulation?”

Melvin Vopson, a physicist at the University of Portsmouth, England, estimated that the minimum number of bits of information in the visible universe could be around 10⁸⁰. (That is 10, followed by 80 zeros.) If you include dark matter, which we can’t see or detect, it could be ten-trillion times that number.

So, do we believe we are in a matrix or base reality? If we believe that this universe is a computer simulation and we are only a relatively few bits in that matrix, you would have to believe that an infinite intelligence wrote the code for the program. However, it seems to me that a more reasonable explanation is that we are living in a base reality created by an infinite intelligence. The most incomprehensible thing is that the omniscient Creator cares about each one of us. (Read Matthew 6:25-34.)

Architectural Abilities of Honeybees

One of the evidences of design in the natural world is honeycomb construction by bees. For many years, engineers have noted that the hexagon is the strongest geometric shape. In geology, we see six-sided columns of basalt produced under ideal conditions inside the Earth. Visible examples of that appear in areas worldwide, such as Devils Tower in Wyoming, where erosion has exposed those columns. Scientists using automated measurements of thousands of honeycomb cells discovered the extraordinary architectural abilities of honeybees.

Many years ago, biologists questioned how bees learned to construct their honeycombs with a six-sided geometry. That shape gives the most storage space with efficient use of building materials. Any other geometric shape would collapse under the weight of the honey. Since a mistake would be lethal, trial and error seems to be an unsatisfactory explanation. Therefore, the genetic makeup of bees must include instructions to build their honeycombs with hexagons.

New studies show the architectural abilities of honeybees to be even more impressive. That is because the structure of the honeycomb is even more complicated than fitting hexagons together. The problem is that not all of the hexagons in a honeycomb can be the same size. Worker bees require a small six-sided structure, but drones require larger cells. However, all of these have to be fitted together into a single sheet in the hive. Researchers have found that bees create intermediate size hexagons to transition from one size to the other.

Also, the bees have to merge combs that are constructed from different starting points. Then, to align them, the bees build special cells with 4, 5, or even 7 sides. The writers of the research report said, “Unlike automatons building perfectly replicated hexagons, these building irregularities showcase the active role that workers take in shaping their nest and the true architectural abilities of honeybees.”

Queen Mary University entomologist Lars Chittka commented, “The hexagonal grid structure of a honeycomb–constructed by a leaderless collective of hundreds of bees–lends itself to speculation that robotic, innate behavior must be at work. But a simple robot does not have such a level of adaptability and rate of error recovery.”

Building even a simple robot is a real challenge to modern-day scientists and engineers. Building the bee’s genetic structure to include the ability to adapt the honeycomb to different needs is incredibly complex. The design of the genetic code for the architectural abilities of honeybees is an excellent testimony to God’s handiwork. God is a creator-engineer giving bees the ability to build honeycombs to accommodate their needs.

Anole Lizards Can Breathe Underwater

Researchers from the University of Toronto wanted to know how anole lizards could stay underwater for up to 18 minutes. To study them, the scientists went to Costa Rica and captured lizards in 32 species of the Anolis genus. They found that anole lizards can breathe underwater.

Their study showed that all species of anole lizards breathe air trapped around their snouts while submerged. The skin of these lizards is hydrophobic (water repellent) and traps a thin film of air between the water and the skin. Because of the lizard’s design, the trapped air ends up in a bubble over its nose. When the lizard inhales, the air bubble deflates. When the lizard exhales, the film traps the air around its nose until the anole breathes in again. You could say the lizard has a built-in “scuba-diving” system allowing it to breathe underwater.

This is another example of very specialized equipment built into living things allowing life to exist in challenging environments. The more we learn about the creation, the more we see specialized systems that enable planet Earth to support an incredible variety of life.

Anole lizards can breathe underwater, and the various species share this survival design. The researchers call it “macroevolutionary convergence.” We call it a shared body design for survival with a built-in design for knowing how to use it. Specialized equipment and behavior show evidence of intelligence in the design of the different varieties of life we see around us. As Romans 1:20 says, “We can know there is a God through the things He has made.”

Human Evolution from Lower Life Forms

According to new research, a majority of Americans accept human evolution from lower life forms. Researchers asked people whether they believed that “human beings as we know them today, developed from earlier species of animals.” The result was that 52% of the people questioned said yes, 36% said no, and 12% said they didn’t know.

The data also shows that only 34% of Republicans accepted human evolution as opposed to 83% of Democrats. The study’s authors say that “religious fundamentalism” is the primary factor obstructing belief in human evolution from lower life forms. They went on to qualify who is a religious fundamentalist by five criteria. They include whether a person believes in a personal God and accepts a literal reading of the Bible. It was also based on how often they attended religious services in a typical week and how frequently they prayed. Finally, the definition involved whether they agreed with this statement: “We depend too much on science and not enough on faith.” Obviously, this is broader than the typical definition of “fundamentalist.”

It would be interesting to see someone study how these numbers correlate with moral conduct, cases of abuse, and other social ills that are increasing in our culture. The survey supposedly used “a representative national sample,” but any study like this would likely have difficulty finding a truly representative sample. For example, data from the Bible Belt would be different from New England, and the nature of the people doing the sampling can skew the data.

As a majority of Americans accept human evolution from lower life forms, we see the educational programs and materials from DOES GOD EXIST? becoming increasingly important. With our culture becoming more polarized, extremists on both sides make progress increasingly difficult.

Ducklings Swimming in Single-File – It’s Because of Fluid Dynamics

We live on the riverbank, and many geese, ducks, and swans swim by our house daily. I have always been curious about why waterfowl tend to swim in a line each time I see ducklings swimming in single-file behind their mother. Researchers at the University of Strathclyde in the U.K. have applied a mathematical and numerical model to find an explanation.

For example, the swimming of the mother duck sets up an interference pattern reducing the wave-drag and propelling the trailing duckling forward as it surfs the wave. In this way, the lead duckling swims in the “sweet spot” behind its mother. With the rest of the ducklings swimming in single-file, the “wave-riding” benefit carries further. After the third duckling in line, a “delicate dynamic equilibrium” is reached in which each duckling acts as a “wave passer,” passing on wave energy to the next one behind without loss of energy.

The lead author of the study is Zhiming Yuan, and he gave the researcher’s description of this design by saying, “It’s so beautiful.” He thinks that there could be applications for maritime technology with shipping firms designing their vessels so they can travel like ducks in a row to reduce fuel consumption.

It seems that evolutionary natural selection would have terminated this arrangement. An eagle wanting a duck or goose meal would have little trouble picking off ducklings swimming in single-file behind their mother. If the birds were moving in random arrangement around their mother, it should be far more difficult to focus on and pick off one of them. Survival of the fittest doesn’t seem to apply to the behavior of the birds that use a single file approach to travel.

We see that this design is built into the DNA of these birds to provide conservation of energy which is critical to their survival. When you look anywhere in the natural world, you will see extraordinary design to allow living things to exist and thrive.

The Overview Effect and What It Can Do

The International Space Station (ISS) has now been actively supporting humans in space for 21 years. Since November 2, 2000, people have continuously resided in that small laboratory looking down on the rest of us, watching sunrises and sunsets sixteen times a day from a different perspective. The experience can be a reminder of how small we are. Astronauts have described a feeling that has been called “the overview effect.”

The overview effect is a change in perspective that many people experience when looking down on Earth from space. We are accustomed to seeing a limited view of our surroundings. However, when a person’s horizon opens to see the circle of the Earth (Isaiah 40:22) hanging on nothing (Job 26:7) surrounded by an extremely thin and fragile atmospheric layer (Job 26:10), the experience can be mind-changing if not life-changing.

The ISS orbits a little over 200 miles (322 km) above Earth’s surface. The Kármán Line at 100 km (62 miles) is the internationally-recognized boundary of space. Recently, commercial space companies have taken private individuals beyond that boundary to view Earth from space and briefly experience microgravity described as weightlessness. Perhaps the most notable was 90-year-old actor William Shatner who played Captain Kirk on the TV series Star Trek. In a tweet he wrote before the flight, he described himself as “a boy playing on the seashore…whilst the great ocean of truth lay all undiscovered before me.”

Shatner’s reaction after he returned to Earth’s surface is very interesting. He shed emotional tears, and here is some of what he said:

“I’m so filled with emotion about what just happened. It’s extraordinary, extraordinary. It’s so much larger than me and life… It has to do with the enormity and the quickness and the suddenness of life and death… To see the blue color whip by you, and now you’re staring into backness…everybody in the world needs to do this. Everybody in the world needs to see this.”

I think Shatner is correct that it would be beneficial for each of us to see Earth from that perspective just once in our lifetime. The overview effect could change our attitude toward many things, including life and death. In addition, it would help us realize just how small we are and how amazing it is that God cares about us. (See Matthew 6:25-34.)
