Do Exoplanets Disprove God?

Do Exoplanets Disprove God?

One of the interesting developments of the past twenty years has been the study of planets orbiting stars other than our Sun. So far, scientists have discovered more than 4,000 exoplanets. Those who believe the formation of Earth and its ecosystem is a product of blind mechanical chance seize upon this fact to affirm that God had nothing to do with the creation. They argue that given enough time and enough planets, life was bound to happen somewhere eventually. Do exoplanets disprove God?

One obvious difficulty with this claim is that the real issue of creation is how time, space, and matter/energy came into existence in the first place. How it got into a form that would sustain life is a matter of whether the creation was designed and planned by an intelligence, or whether it was a product of chance. Astronomy magazine, in its January 2020 issue, carries an article about the summer 2019 discovery of the first planet that exists in the habitable zone of its star. The media at that time made wild claims about the probable existence of life on that planet. Known as K2-18b, the planet orbits a red dwarf star which is about one third the mass of our Sun. What that means is that water could exist on the planet as a liquid.

So could life exist on K2-18b? This discovery highlights the incredible complexity of planet Earth. K2-18b is roughly twice the diameter of Earth and eight times as massive. The mass of the planet means that gravity there would be much higher than Earth’s gravity. That would result in a much deeper and denser atmosphere with pressures and temperatures thousands of times higher than we experience on Earth. Also, red dwarf stars emit powerful flares, and the orbit of K2-18b is twice as close to its star as Mercury is to the Sun. There is no way that life could survive the conditions on this planet, even if liquid water were present.

Remember that K2-18b is the first planet discovered that is located in a so-called habitable zone. The study of exoplanets has shown that the creation of planet Earth is a highly unique and special event. Do exoplanets disprove God? As we have said before, God can create life anywhere He wants to. But as more and more data becomes available on what exists throughout the cosmos, support for God as the creator and sustainer of life on this planet grows.

Stirring the Pot – The Sun and Parker Solar Probe

Stirring the Pot - The Sun and Parker Solar Probe

If you do any cooking, you know that to be a successful cook, you have to stir the pot every so often. Not only does stirring the pot prevent the food from sticking to the bottom, but it also improves the flavor by mixing the ingredients. The Earth and its relationship to life is also a kind of pot. We are just beginning to understand how complicated the relationship is between the Sun and the various ecosystems on Earth that allow life and advanced life to exist.

In 2018 NASA launched a probe called the Parker Solar Probe to fly near the Sun and make measurements and observations. No space probe has ever been close enough to the Sun to gain much data, but this probe was designed to fill that gap in our knowledge. At this point, it is about halfway between the Sun and Mercury, the closest planet to the Sun.

The Sun has what are called switchbacks when the magnetic field briefly reverses itself. This reversal varies the amount of solar wind coming to the Earth. This variable wind compresses Earth’s atmosphere, stirring the pot, so to speak. The mixing of the gases makes changes in our atmosphere, which we can observe in the auroras. The magnitude of the switchbacks also affects our power grids and orbiting communication satellites.

It is obvious that the movement of materials in our atmosphere and the constant changes that take place are part of the solar system design. The new data may open doors not only to how we can protect our power grids, but it may give us further understanding of the origin and sustaining of life on Earth.

Stirring the pot is one more factor in the intricate design of our planet and solar system that makes life possible. When Proverbs 8 talks about wisdom being present before the creation, it speaks of things we are just beginning to understand. The more we know of the creation, the more we know of the Creator.

Milk Production and Greenhouse Gases

Milk Production and Greenhouse GasesHow do you feed millions of humans and meet their nutritional needs without destroying the planet with greenhouse gases? The World Wildlife Federation has released data on one of the primary sources of food for more than six billion people worldwide – milk. The average person in the United States consumed 643 pounds (292 kg) of dairy products in 2017, including milk, butter, cheese, yogurt, and ice cream. Those foods came from 9.3 million dairy cows, but there are 278 million in the world. Milk production has grown by 30% from 2005 to 2015, and that comes to 909 million tons. India is the leading producer with 20% of the world’s supply. The U.S. has 12%.

The design of cattle that can produce that much milk was recognized in prehistoric times, and cattle were worshiped because they provided so much food for humans. Skeptics would respond that the environmental impact of cattle is so huge that it is a bad design. It does take 144 gallons of water to produce one gallon of milk in the U.S., with over 93% of it involved in growing feed for the cattle. The average dairy cow will eat 100 pounds of feed, and 9% of American cropland is used to grow feed crops for dairy cows. A cow will produce 17 gallons of urine and manure, which can pollute rivers and lakes, and they generate greenhouse gases.

The fact is that only 2% of the total U.S. emission of greenhouse gases comes from milk production. The Northern Great Plains cover 180 million acres in Montana, Nebraska, North Dakota, South Dakota, Wyoming, Alberta, and Saskatchewan. The land became rich in resources and healthy when grazing animals such as bison aerated and fertilized the soil. With the past numbers of those animals gone, scientists now say that something else must fill that niche or erosion will increase, and invasive plants will take over. Studies by the World Wildlife Federation show that cattle production areas in the Northern Great Plains have lower per acre emissions than row crop agriculture such as corn, soybeans, and wheat. The most recent study shows “done right, ranching can help conserve biodiversity while minimizing its own environmental footprint.”

Like everything else that God has given us, milk production must be managed carefully and with a concern about “taking care of the garden, dressing and keeping it” (Genesis 2:15). Milk is one of God’s great blessings, and a land “flowing with milk and honey” is held out as the most favorable place to live.

Rossby Waves and Earth’s Climate

Rossby Waves and Earth's ClimateWe have previously discussed the movement of air around the Earth, and the circulation pattern called the Hadley cells. Another important factor in Earth’s climate is Rossby waves.

Because the equator is hot, heated air rises and moves away from the equator, dropping its moisture as it cools. At about 30 degrees latitude, the now dry air falls back to the Earth, producing deserts. As the air reaches Earth’s surface, it moves north and south, creating the trade winds in the subtropical area and the prevailing mid-latitude winds in latitudes between 30 degrees and the polar regions.

A wide range of things alters this simplified picture. When greenhouse gases like carbon dioxide accumulate, they reflect infrared radiation causing the Earth’s atmosphere to become hotter. This effect isn’t uniform, however. Because of melting sea ice, Earth’s poles are affected by greenhouse gases more than the area of the equator. This causes a thermal imbalance between the poles and the equator affecting circulation around the poles and creating Rossby waves.

As the thermal imbalance has become greater and the air more wobbly in recent years, that affects the jet stream. The wobbles this past year have caused the northern jet stream to go further south than usual, bringing cold into Arizona in late spring. When the jet stream swung north, it brought hot tropical air toward the poles. On its way north, it brought unusual amounts of water into Oklahoma while Anchorage, Alaska, got temperatures over 90 degrees for the first time ever. Rossby waves is the name applied to the meandering high-altitude winds that have a major influence on Earth’s weather.

All of this shows us how fragile Earth’s climate is. Weather patterns depend on a wide range of variables which include the:
*size of the Earth’s atmosphere
*tilt of the Earth
*distribution of land compared to water
*chemical makeup of the atmosphere
*kind of radiation coming from the Sun and how that radiation is absorbed and reflected
*nature of Earth’s surface (whether ice or black dirt)
All of those factors go into making Earth a habitable planet.

We exist on this planet because of the precision design and construction of Earth and its atmosphere. The fact that it has stayed stable long enough for human life to exist for thousands and thousands of years is a testimony to the careful design and construction. Proverbs 8 finds “wisdom” speaking about its role in the creation process. Wisdom says she was there before the creation (verse 22-23) and that wisdom was a part of the preparation of the heavens (verse 26-28).

As we see the results of the small changes that have happened to the atmosphere in the past 100 years and the instability of Rossby waves, we wonder at Earth’s design and the wisdom of God who created it.

What the Mercury Transit Tells Us

What the Mercury Transit Tells UsAbove is a photo of the Sun. If you look closely, you will see a small dot in the upper half near the right side. That is the planet Mercury, the closest planet to our Sun. Mercury made what astronomers call a “transit” of the Sun on Monday morning, November 11, 2019. In our area of the country, the sky was overcast, and it was snowing. However, Bill Ingalls of NASA took this photograph from his location in Arlington, Virginia. I find it interesting to consider what the Mercury Transit tells us.

What’s so special about Mercury passing in front of the Sun? For one thing, it doesn’t happen very often. Although the last time was only three years ago, the next time will be in 2032, but it won’t be visible from North America. The next Mercury transit visible in North America will be in 2049. Since Mercury is closer to the Sun, it passes between the Sun and us every 116 days. However, most of the time, it is either above or below the Sun from our view, and Earth’s atmosphere makes it invisible in the daylight.

Scientists used precision telescopes and equipment to study the transit. They can learn more about the atmosphere of Mercury as it is silhouetted against the Sun. Historically Sir Edmund Halley (1656-1742) watched a transit of Mercury and realized that it could be used to measure the distance between the Earth and the Sun. It occurred to him that a transiting planet would appear in different positions to viewers in different locations on Earth. Measuring the apparent shift between two distant Earth locations at the same time and applying a little math, one could calculate the distance to the Sun. In 1769, after Halley’s death, astronomers used a transit of Venus to calculate the Earth-Sun distance.

Think about what the Mercury transit tells us without even seeing it? Because of the fact that astronomers can know in advance the exact date and time of a transit of Mercury (or Venus), or a solar eclipse (when the Moon passes between Earth and Sun) we realize that the solar system is orderly. We can study the heavens and learn of the Creator. We can see His wisdom and design of our planet and the solar system in which it exists. We can know there is a God by the things He has made (Romans 1:20) as the heavens declare His glory (Psalms 19:1).

Space Debris: A Growing Concern

Space Debris: A Growing Concern to Astronauts in SpaceA significant issue for the future is our total lack of care for the planet on which we live. We not only have the problem of plastic waste and carbon dioxide emissions, but now we have the issue of space debris.

From 1957 when the space age began, until January of 2019, humans have placed nearly 9,000 satellites in Earth orbit. More than half of them, around 5,000, are still in orbit, and 1,950 are still functioning. In addition to the satellites, there is debris from all this activity. The European Space Agency tells us that there are 130,000,000 pieces of debris larger than .04 inches in orbit around Earth. The number of articles between .4 inches and 4 inches is 900,000, and 34,000 are 4 inches or larger.

What all of this space debris does to Earth’s neighborhood is becoming a concern to scientists. It creates a danger of collision with operating satellites or crewed spacecraft, such as the International Space Station. That danger becomes especially apparent when you realize that space debris can be traveling at speeds up to 17,500 miles per hour (28,100 km/hr). The threat obviously increases as we continue to orbit objects of all kinds, leaving more junk in space.

Why is it that we have to have a tragedy to make us realize the importance of being good stewards of what God has created for us? God gave us the responsibility to take care of the Earth, and He has not rescinded that duty as we develop new technology.

Care and Maintenance of Pets

Care and Maintenance of PetsI am totally in awe of how much pets mean to people and how much they do for their owners. As people become more and more aware of the need to take care of planet Earth, they realize the environmental impact of the care and maintenance of pets.

When God created life on this planet, He built balance into all life. There were natural limits to the population of animals. There was a healthy relationship between prey and predator. Then humans killed off certain predators and transported animals to new areas where they had no predators. They sometimes adopted wild animals as pets and later released them or allowed them to escape into the wild. Those actions upset the balance, and today we are paying the price for that disturbance.

The United States Fish and Wildlife Service tells us that cats, many of them feral, kill billions of birds every year. The International Union for the Conservation of Nature reports that wild and free-roaming dogs are a threat to the survival of almost 200 species around the world. Sometimes people obtain a cute baby crocodilian for a pet, and when it grows too large, they release it into the wild where it can become a danger to other animals or people. The Florida Everglades has a problem with Burmese pythons, which people released when they became too large for pets.

We have a great responsibility for control of the animals that God has given us to oversee. God said, “Have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moves upon the face of the earth” (Genesis 1:28). That doesn’t mean to destroy them. It means to take care of them and work to produce proper management of their lives. The selfishness and greed of humans harm the planet on several levels, including puppy mills and the neglect of animals in our control. The care and maintenance of pets is an area where we need to do better.

Moon Record in the Solar System

Moon Record in the Solar SystemThe solar system record for the largest number of moons has just been taken over by Saturn. Previously Jupiter was the record holder with 79. (Update April 2026- 101.) Now the moon record in the solar system goes to Saturn with 82! (Update April 2026- 285.)

Astronomers used some of the world’s largest telescopes, including the Subaru Telescope in Hawaii to make the recent discoveries. The same team led by Scott Sheppard of the Carnegie Institution for Science in Washington, D.C., discovered 12 previously unknown moons around Jupiter last year. Now they have helped Saturn pull ahead of the competition.

Here we are living on a planet with only one Moon. Should we feel disadvantaged? Not at all! Imagine how confusing it would be to live on a planet with 82 moons. Seriously, one is enough. That is especially true when we have one Moon that is just right. We have pointed out before how precisely well-designed and well-placed our lone Moon is. Here are a few reminders with links to get more information:

Our Moon…
…has just the right mass to stabilize Earth’s rotational tilt.
…is just the right distance from Earth to create beneficial ocean tides.
…is just the right size to create total solar eclipses, which have helped us to learn more about the Sun.
…works with the Sun and stars to “mark seasons and days and years” (Genesis 1:14)
…reflects the light of the Sun to give a night light essential for many forms of life.

Those are a few of the reasons our Moon is the best one in the whole solar system! We asked before, “How many moons are enough?” Even though the number of known moons orbiting Jupiter and Saturn has changed since we asked that question, the answer is still the same. One Moon, precisely designed and positioned, is exactly what we need. We hold the moon record in the solar system for the best Moon of all! There are too many “coincidences” for it to be an accident. We see the work of a Creator, who is an amazing Engineer.

Why We Need Lightning

Why We Need LightningAll life forms on planet Earth need nitrates to build proteins and DNA. We get our nitrates from the plants and seeds that we eat. Plants absorb nitrates from the soil through their roots. The nitrates in the soil come from rain that has absorbed nitrates from the air through which it falls. The nitrates in the air come from the action of lightning. Our atmosphere is 78% nitrogen, and lightning takes some of the nitrogen and catalyzes it into a bond with oxygen to make nitrates. That is why we need lightning.

A surprising thing about this complex system is that the lightning is far more abundant than we realize. Lightning strikes the Earth around 1000 times every second. Above the clouds, in the upper atmosphere, there are continuous lightning types that we don’t see from Earth’s surface. They are called elves, sprites, blue jets, and gigantic jets, depending on their color and shape. There is a voltage difference between the ground and the ionosphere, which varies from 200,000 volts to 500,000 volts. Even in fair weather, there is a constant flow of current, which scientists believe is caused by the spinning of Earth’s core. All of this adds up to a total of over three million lightning strikes a day, and each produces nitrates to sustain life. The jet stream carries these nitrates around the planet, providing a natural fertilizer in places where electrical storms rarely occur.

The Old Testament contains suggestions of this being a part of God’s design for life on Earth. Ecclesiastes 1:6 talks about wind patterns, and Jeremiah 10:13 speaks about lightning. Job 36:29 and 37:21 speak of clouds and bright lights. Lightning is sometimes destructive, often because of foolish construction by humans or ecological problems caused by human mismanagement. In reality, lightning is a tool God uses to build and maintain life on Earth. That is why we need lightning. The more we learn of the creation, the closer we get to the Creator.
