We Need Lightning to Survive on Earth

We Need Lightning
Most of us have had some experience with lightning. The chances are that our experiences have been terrifying and destructive, and we may view lightning as a bad thing. You may wonder if we need lightning. The short answer is, “Yes.” Lightning is a good thing, and there are many things we are still learning about it.

Lightning helps produce the nitrates and other nitrogen compounds that are needed by all living things on Earth. The process is called “nitrogen fixation, ” and it is vital to our very existence. Water droplets in the air carry an electric charge. That charge can accumulate to dangerous levels unless there is a way to neutralize it. That’s where lightning comes in.

One of my favorite demonstrations as a physics teacher was to get a very small flow of water going from a faucet and then bring a charged rod up to the column of water. The stream of water will bend in response to the charge. That is because the polar nature of the water molecule allows it to have electrical properties. Because of water’s electrical property, lightning is generated to release nitrogen from the air and deposit it in the crust of the Earth as nitrates and other nitrogen compounds that plants need to grow. The plants then feed and protect the animals and us.

Low Earth orbit satellites and high flying airplanes have recently made us aware of other properties of lightning. We have learned that red sprites occur and they have been photographed above large thunderstorms. Other upper atmosphere lightning phenomena include blue jets and terrestrial gamma flashes. Scientists are studying the highly complex nature of lightning to understand how the system works.

The Bible makes many comments about lightning. It tells us that lightning is made with water (rain) even though people at that time totally ascribed lightning to supernatural causes. (See Jeremiah 10:13 and 51:16). Lightning is referred to as a tool of God. (See Job 28:26; 36:30; 37:3, 11, 15; 38:24, 25, 35.)

We are just beginning to understand the design of Earth’s atmosphere and why we need lightning. It continues to be obvious that the more we know of the creation, the closer we get to understanding the power and wisdom of the Creator.

World’s Largest Snake- TITANOBOA

World's Largest Snake
It was the world’s largest snake. Fortunately, it is extinct. The computer-generated picture shows what it might have been like if a human had ever confronted a Titanoboa (Titanoboa cerrejonensis).

One thing that many creationists and evolutionists forget is the fact that Earth’s climate in the past was much different from what it is today. To produce animals of massive size, Earth’s climate would have to be much warmer. The temperatures would have been so high that mammals could hardly survive. Cold-blooded (ectothermic) animals in tropical areas today tend to be larger than ectothermic animals found farther from the equator.

While giving lectures in Colombia, South America, we learned about the snake named Titanoboa. Fossils of more than two-dozen of these snakes were discovered in coal mines in northern Colombia. The name means “titanic boa,” and that seems fitting because it measured 48 feet (14.6 m) long and would have weighed 2500 pounds (1,135 kg). For a snake of that size to live, the climate must have averaged 90 degrees F (32 degrees C). It is difficult to comprehend how any mammal, especially humans, could survive in such temperatures.

Why would God have given this planet such an extreme climate? It was needed to support the world’s largest snake, other huge animals, and the massive vegetation they required. What was the purpose of those animals and plants? That environment made possible the coal, petroleum, and other resources that would later be needed by humans to support an advanced civilization. This is one more indication that the prehistory of the Earth had conditions uniquely designed by God to prepare the planet for human habitation.

Cobra Plant Insect Trap

Cobra Plant
One of the most interesting areas of botany is the functioning of plants that don’t rely on photosynthesis to survive. Recent studies of the California pitcher plant (Darlingtonia californica), also known as the cobra plant because of its shape, have shown that its design is incredibly complex.

David Armitage at the University of Notre Dame has been studying this plant, and in a recent article in Science News (January 21, 2017, page 4) he reported on what is known about this strange plant. It grows in soil rich in serpentine which would kill most photosynthetic plants. The cobra plant survives by being “meat dependent.” Up to 95% of the nitrogen the plant uses comes from insects trapped inside the leaves of the plant.

The curled leaves of the California pitcher plant serve as an insect trap. It draws insects into the leafy trap by secreting a sweet substance. This secretion is not through its blossoms but from a special roll of tissue near the mouth of the insect trap. When an insect enters the small opening under the cobra-like head of the pitcher, something interesting happens. By a method still not understood, the cobra plant draws water up from the soil and creates a pool in the bottom of the “pitcher.” Putting other substances into the trap doesn’t trigger the water. The plant will only respond to an insect. How the plant knows what is a bug and what isn’t a bug is still not understood. The water contains bacteria which lower the surface tension, so when a bug falls in, it quickly sinks to the bottom and drowns.

Another unsolved mystery of this plant is that it has a forked tissue at the top of the trap called a “fishtail” which resembles a mustache with red veins. It does not lure insects into the plant, but its function is still not understood. Armitage says “The only thing fishtails lure, for the time being at least, are puzzled botanists.”

Those of us who see God’s designing hand in the natural world would see the cobra plant as a special design to meet a particular environment. We would point to the Bible in Romans 1:20 where it says, “We can know there is a God through the things he has made.” The complexity of the California pitcher plant supports such a viewpoint in a special way.

Dinosaur Pseudoscience Part 2

Dinosaur Pseudoscience Fire-breathing
Yesterday we stated that one of the greatest challenges that this ministry faces is the bad science and false claims by creationists, including dinosaur pseudoscience. In addition to the ones we mentioned yesterday, another example is the claim of many creationists that dinosaurs were fire-breathing dragons.

In the Middle Ages, there were numerous stories about flying dragons who breathed fire. In recent years we have seen movies showing everything from Puff the Magic Dragon to How to Train Your Dragon as well as video games showing dragons that look like dinosaurs. Creationists have proposed that dinosaurs had hypergolic chemicals (chemicals that ignite when combined) that they used to produce literal fire. The scientific problems with such proposals are huge. Hypergolic chemicals are highly toxic to biological organisms. Fire going out of an animal’s mouth or nose would cause damage to the tissue. Atheists and biblical skeptics have written numerous articles showing the impossibility of these proposals on a scientific basis.

What is the biblical passage that creationists use to suggest that dinosaurs were fire-breathing dragons? The answer to that question is Job 41. The key word in this chapter is “leviathan.” The word is used three other times in the Bible–Psalms 74:14, Psalms 104:26, and Isaiah 27:1 In all of these references the leviathan is a sea creature. In other non-biblical Hebrew writings the word is used to describe a sea creature, and in a few cases, a sea crocodile is the translation. Job 41:18 says that when leviathan sneezes a light shines and his eyes look like the dawn. Verse 19 says that fire comes from his mouth and verse 20 says that smoke comes from his nostrils. This is poetic language and obviously doesn’t describe the animal anatomically. Verse 29 says that the leviathan laughs and verse 31 says that he makes the sea boil like a pot of ointment. These are obviously poetic descriptions of a very fierce sea creature. It is not a dinosaur living on the land, flying, and belching fire.

There is no valid fossil support for humans and dinosaurs living at the same time, and there is no biblical passage that states it. Cherry-picking a poetic description in Job to back up a denominational belief system is not taking the Bible literally.

Those of us who believe in God are in a war with forces who wish to destroy Christianity and the Bible. Pseudoscience used to defend a denominational understanding of a biblical passage just becomes a tool of those who despise Jesus Christ. It is a tool they use to destroy the faith of bright and well-educated young adults. We must not give them that tool.

Underwater Bees

Seagrass and Green Sea Turtle
Seagrass and Green Sea Turtle

Those of us who live many miles from the ocean may not think about what goes on under the water. Similar to the land, there is an enormous diversity of plants in the sea. Just like land plants, ocean plants have flowers and pollinate and reproduce. Seagrass grows on the floor of the ocean and provides habitat for sea turtles, manatees, and many other marine animals. There are some 60 species of seagrass, and those grasses bloom and release pollen. Like land plants, seagrasses need something like the bees that help pollinate land plants. So are there underwater bees?

Researchers at the National Autonomous University of Mexico have reported that hundreds of crustaceans and other small insect-like animals visit plants and bring pollen with them. These invertebrates are the “underwater bees.” Along with ocean currents, they allow ocean vegetation to flourish.

As scientists study ways in which carbon can be locked up to avoid high concentrations in our atmosphere, they find that the ocean is a major factor in avoiding runaway greenhouse heating of the earth. Life in the oceans is essential to life on land.

Here is another design feature of this planet which is critical to the long-term existence of life on Earth. In the 1950s, scientists thought that there were maybe five or six factors which would be critical to the existence of life. The famous Drake Equation of how many planets could have life on them only considered five factors in its original format. Now we know there are a huge number of things that have to be “right” to allow life to exist.

Every time we find a new variable, the odds against life occurring by chance on planet Earth become greater. God’s wisdom and design can be seen everywhere around us. Truly, “the heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1).

Science and Theology

Science and Theology

There has been a growing trend in the academic community to suggest that science and theology are two separate disciplines that cannot support one another. The position of this ministry has always been that science and faith complement each other and should never be viewed as opponents. The dictionary defines science as “systematic knowledge.” It defines theology as “science dealing with God and His relationship to the universe.” (Webster’s American College Dictionary) Bad science and bad theology are very much the same–systematic knowledge replaced by human opinion.

In the physical world, science is based on a method that precludes human opinion. The scientific method involves testing a theory by experimentation to see if it can be falsified. We can even expand and enlarge our fundamental knowledge. Our understanding of gravity, for example, has undergone several changes since Newton’s day when the first knowledge was derived by the tests available to him. When Einstein gave us an expanded understanding of gravity, it was based on several tests which could be duplicated over and over. Now there is a possibility that Newton’s ideas will be expanded even more as better experiments enlarge our understanding.

Interestingly, Isaac Newton also did experiments in theology. In theology, his experiments did not verify his personal opinions, so they never became science. Like much of astronomy, quantum mechanics, and cosmology, experiments in theology have to be conducted by observation of things we can’t control. Science provides facts about the physical world and our role within it, and many of those facts have theological implications.

Do our understandings in theology change? Certainly! Just as our understanding of gravity has grown, so too our understanding of God has grown. As we experience life and see what has happened in human history and in our own lives, our understanding grows. Even our understanding of the Bible has grown as we learn more of what Jesus and the Apostles taught and how they lived. Knowing that the cosmos is not just the Earth and the solar system has expanded our understanding of God and His power and intelligence. It is bad theology to take the knowledge of 500 years ago and force our understandings of the Bible on that knowledge.

The twenty-first century is an exciting time to be alive. As our scientific knowledge continues to grow, so too our understanding of God is growing and expanding. Proverbs 8:1 and 22-30 shows how wisdom was involved in all of God’s creation. If we use our God-given intelligence and take His Word as truth, we can grow in our faith and in knowledge.

Oxygen Level Factor and Life

Oxygen Level
The atmospheric oxygen level in Earth’s early history allowed life-forms to grow much larger than they do today. We find fossil remains of insects that grew to incredible sizes. There are wonderfully preserved fossils of a dragonfly called Meganeura which was the size of a modern-day hawk. Ants a foot (30 cm) long and centipedes that were as long as two feet (61 cm) show up in the fossil record. There are also fossils of mammals that were larger than any land mammals living today.

A major key to the huge sizes is the amount of oxygen in the atmosphere at the time those animals lived. New laboratory techniques in nuclear chemistry give us accurate methods of determining the oxygen level of the atmosphere in the past. Ice cores and tree rings confirm the measurements. Studies show that Earth’s atmosphere has had oxygen content as high as 35 percent in the past compared to 21 percent today. This higher oxygen level would have some negative consequences, with fires burning much hotter and faster and corrosion happening faster. Its effect on some living things, however, would be very positive.

Laboratory experiments have also shown us how oxygen content affects the size of living things. Insects do not breathe with lungs since oxygen diffuses into their bloodstream directly. Dr. Robert Berner at Yale has shown that a 35 percent level of oxygen in the atmosphere would increase the diffusion rate of oxygen in an insect’s bloodstream by as much as 67 percent. Body size varies directly with oxygen concentration, and experiments with fruit flies and mealworms consistently show high growth rates with increased oxygen. Studies done on alligators have shown that variations in egg development and growth are in direct proportion to the oxygen in the atmosphere. It is the same for mammals. Dr. Paul Falkowski of Rutgers has said, “Pound for pound, mammals typically need three times as much oxygen as reptiles do.” An oxygen level that would support reptiles might not support mammals.

All of this is very helpful in understanding a variety of issues relating to the Bible and the evolution/creation controversy. It is increasingly obvious that dinosaurs and humans could not survive together on this planet. At the time of the dinosaurs, the oxygen level was too low for mammals to survive. Competition for food and living space between humans and dinosaurs would be most difficult. Domestication of reptiles is impossible so humans would not be able to train dinosaurs to help with heavy chores.

The Bible does not mention dinosaurs, and no Hebrew word in Genesis 1 could legitimately be interpreted to mean dinosaurs. The emphasis that the Bible gives to the breath of living things as seen in the Hebrew word “nephesh” becomes more and more relevant as we learn more about how vital that concept of breath is. (See Genesis 2:7; 7:22, etc.)

Many people seem to feel that dinosaurs were unnecessary to human existence and that their presence denigrates evidence of God’s creation. The balance between the composition of the atmosphere and the abundance of life on Earth is critical. For plants to grow, there has to be soil, and soil is not as simple as it looks. Dirt must have the critical elements for food chains and cell reproduction. The production of all of those resources is not simple. As plants take in carbon dioxide and lock carbon into the soil, they release oxygen into the atmosphere. The ecological system of the planet at the time when the dinosaurs lived allowed not only the formation of soil but also the massive amounts of coal and fossil fuels we need.

We take air for granted, but what we see of the past in the laboratory and the fossil record tells us that the biblical emphasis on the “breath of life” is a special gift of God, and is not to be taken lightly.

Coccolithophores and Carbon

Coccolithophores in the Black Sea
Coccolithophores in the Black Sea

In our day of concern over carbon emissions and global warming, it is always good to see something positive taking place in the environment. Every day there is a new view in space posted by NASA at the website apod.nasa.gov. On April 24, 2017, there was a photograph taken from space of the Black Sea showing a bloom of coccolithophores. So what are they and why should you care? Coccolithophores are phytoplankton, tiny organisms that live in the large bodies of water such as oceans and seas around the world.

Why should you care? The answer to that has to do with carbon dioxide in the atmosphere. There are also viruses called coccolithoviruses that attack the coccolithophores. To protect themselves, they absorb carbon dioxide from the air and combine it with calcium to make shells of calcium carbonate–chalk. The White Cliffs of Dover are made of this chalk material that was produced by coccolithophores. In the process of protecting themselves, these organisms remove carbon dioxide from the air. It appears they may have been the agents that allowed oxygen to rise in our atmosphere to the level where animal life could exist.

The coccolithophores are very complex, and the process is good solid chemistry. The bloom that is visible from space of the coccolithophores in the Black Sea tells us that there are balances built into the earth to help reduce greenhouse gasses. It also says that this is a designed tool to allow life to exist on planet Earth. Everywhere we look on this planet, we see that a wonder-working hand has gone before. Even looking back at the Earth from outer space we can see what that hand has done and continues to do to allow us to survive.

Earth Movers

Echidna
Echidna

They are designed to move dirt. The echidna is one of only two mammals that lay eggs. (The other is the duckbilled platypus.) Every year the short-beaked echidna (Tachyglossus aculeatus), lays one leathery egg which is about the size of a grape. The egg is put into the mother’s pouch, and it hatches in about ten days. Two patches of pores in the pouch ooze milk and the baby, which is called a puggle, laps the milk from the mother’s skin. The baby hangs on to the mother for weeks as she forages. When it the starts growing spines, the mother will put the puggle into a burrow, and it is on its own.

Echidnas get their food by clawing and poking their snouts into termite hills or ant nests. They flick out their sticky tongues and draw in the insects. The echidnas’ toes point backward on their hind legs and forward on the front. Their short legs slant outward, and they move both left feet at once and then both right feet at once, so they rock as they walk. They may look awkward while walking, but they are well-designed to move dirt. Echidnas spend 12% of their day excavating so that in a single year each echidna will churn up 204 cubic meters of soil. That’s enough to bury 100 full sized refrigerators.

Turning over the soil mixes nutrients and aerates the soil to benefit the Australian ecosystem in which the echidna lives. The echidna improves the soil while removing ants and termites making this animal an important part of God’s design for this planet. Everywhere we look we see testimony to the wisdom of God.

Global Citizens

Globe Skimmer Dragonfly
Globe Skimmer Dragonfly

One of the most interesting examples of design in living things is the ability that various forms of life have to migrate great distances for a wide variety of reasons. Sea turtles have an uncanny ability to return to the same beaches over and over to lay their eggs. Whales can travel long distances when they are ready to calve, giving their offspring a greater chance of survival. Migrations can be critical to animals or plants other than the animal making the migration. Sometimes the migration is critical to an environmental ecosystem. The salmon migration in Alaska, for example, is critical to the entire area sustaining plant life and a wide variety of animal life.

When insect migrations are studied, the question of how they make the migrations and why becomes even more complicated. Monarch butterflies make migrations of great lengths even though their life expectancy is too short for any single butterfly to make the entire migration. The champion of insect migrations is the globe skimmer dragonfly (Pantala flavescens). This insect has wide wings that look very delicate, but those wings can carry it for thousands of miles seeking wet seasons when it can reproduce. Migration has spread this insect’s DNA worldwide to every continent except Antarctica. Globe skimmers can fly for hours without landing and have been seen as high as 20,000 feet (6,200 m) in the Himalayas. They are sometimes called wandering gliders because they can glide on thermals in a way similar to birds. They seem to prefer moist winds, and they don’t stop for bad weather.

Migration is a fascinating part of the life of many creatures from whales to insects. Especially when we think of migrating insects like monarch butterflies and globe skimmers, it seems obvious that the ability and desire to make the migration are programmed into their DNA. We would suggest programming needs a Programmer.
