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?”

Non-Native Species Invasion

As we look at the flora and fauna of our world, we see a beautifully designed system. Plants and animals sustain each other in a balanced network of life, but problems arise when humans do things that upset that balance. One way we do that is by accidentally or intentionally causing a non-native species invasion with no natural predator or forager. The species then has no control factor to balance it, and plant growth or animal reproduction becomes out of control.

An example of a non-native species invasion is the kudzu plant. This vine can grow up to a foot per day and is known as “the vine that ate the south.” It has taken over parks, roadsides, and forests in some areas. Kudzu vines wrap themselves around the trunks of native trees, out-competing their host for sunlight and even nutrients by girdling its bark and strangling the tree.

Kudzu is native to Asia and some Pacific islands, but people brought it to North America as a decorative plant in the 1870s. As late as the 1940s, the U.S. government urged farmers to plant it to prevent soil erosion, and people promoted it as a fast-growing plant to shade porches. The consequences of human actions have become evident, costing millions of dollars.

One of the worst U.S. invaders is the inappropriately named tree of heaven (Ailanthus altissima ), native to areas of China and Taiwan. It was brought to the United States in 1784 as a decorative tree. However, its habits of sending out shoots, known as suckers, colonizing areas, and suppressing competition by producing chemicals that inhibit the growth and reproduction of other plants. This non-native species invasion also creates an objectionable odor and hosts another invasive species, the spotted lanternfly (Lycorma delicatula). Eradicating this “tree of hell,” as some call it, is difficult because if you cut it down, it will quickly regrow from new shoots.

All of these invasive species serve a purpose in their native lands, where they fit into the balance of the natural world. The problem comes when humans upset God’s balanced system. In many ways, humans have not been good stewards of the job God assigned us to “rule over” the Earth (Genesis 1:26) and “work it and take care of it” (Genesis 2:15).

Extraordinary Claims Require Extraordinary Evidence

It’s known as the Sagan standard and abbreviated ECREE. Carl Sagan, an American scientist, and agnostic, hosted the PBS program Cosmos in the 1980s. He said in the series, “I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence.” He was talking about claims that aliens from space had visited Earth. But we can apply the principle to more than alien visitations.

The truth is that Sagan did not originate the ECREE concept. He just popularized it on television. The idea had been previously expressed many times by others. Even Thomas Jefferson described it in a letter he wrote in 1808 about the existence of meteorites, but he was much more wordy. (He used about three dozen words instead of Sagan’s five.)

What does the Sagan ECREE standard mean? It tells us that when we make an extraordinary claim, we must back it up with extraordinary evidence. How about the extraordinary secularist claim that everything we see came from nothing by means of nothing? If matter, energy, time, and space all originated at the “big bang,” and nothing existed before that, where is the extraordinary evidence to back up that claim? Could an eternal God existing outside of time and space be a better explanation for the universe?

If one claims that life originated from non-living chemicals without intelligent guidance, what is the extraordinary evidence for that? Even if science succeeds in creating life from non-living chemicals in the laboratory (and they are far from doing that), it would merely prove that intelligence can create life from non-life. That is what the Bible has said for thousands of years.

Once life got its start, what is the evidence that it evolved from species to species until it reached homo sapiens? We don’t see any extraordinary experimental or fossil record evidence of that either. To prove that natural selection acting on random mutations could accomplish a task that defies the second law of thermodynamics requires extraordinary evidence, which we don’t have.

We agree with the Sagan standard that “extraordinary claims require extraordinary evidence” (ECREE). The question is, does all that we see in the universe and on our planet give extraordinary evidence of unguided random chance or design by an intelligent Creator?

Losing Hope in the Future

One serious problem facing our society today is a lack of hope. Polls show that most Americans think the country’s best days are behind us. When asked if the country is going in the right or wrong direction, the vast majority say it is going in the wrong direction. Losing hope creates a downward spiral that only gets worse.

Losing hope is a serious problem for society. Hope is what you have when you are looking forward to something better. It involves waiting in anticipation of a better day. When people lose hope, they fear what tomorrow might bring and become discouraged. They may even become angry and vent their frustration on others or themselves. We see that especially among young people, and most of all in girls.

When young people are being taught that they are mere accidents of evolution and their life has no ultimate meaning, it’s not surprising that they are losing hope. When they see no purpose in life and no hope for a better future, we should not be surprised to see them take out their anger on society.

What a difference it can make in the lives of young people if they have the reassurance that they are loved and their lives have purpose and meaning. However, adults can’t give hope to young people if they don’t have it themselves. That is something that Christianity can give. A Christian can look forward to a better day regardless of present circumstances. We know that God is in control and that He loves us, as Jesus taught and demonstrated.

The late Christopher Hitchens would say that “religion poisons everything.” In some ways, that is true. The religion of Darwinian materialistic evolution has been poisoning our young people and destroying their hope, but Jesus restores hope. He said, “I have come that they may have life, and that they may have it more abundantly” (John 10:10).

The Sermon on the Mount recorded in Matthew chapters 5-7 is the most excellent discourse on how to live a life of love and hope. If you are losing hope, read those chapters and put the words of Jesus into practice. I guarantee that it will change your life for the better.

Searching for Signs of Alien Life

The National Aeronautics and Space Administration (NASA) is searching for signs of alien life in the universe. NASA’s astrobiology program is renewing efforts to answer the question, “Does life exist elsewhere in the universe?” We find life all over this planet. Life is everywhere on Earth, from frigid climates to arid deserts and ocean depths to mountaintops. But does it exist anywhere else?

Currently, NASA is searching for microbial life on Mars with two robotic rovers, Curiosity and Perseverance. Those rovers are exploring rocks in fossilized waterways on the planet, seeking any indication that microbes once lived there. NASA and the European Space Agency (ESA) are working to develop a Mars sample return mission to bring rocks back to Earth for closer examination.

In December of 2018, NASA spacecraft “Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer” (OSIRIS-REx) arrived at the asteroid Bennu after traveling for two years. It orbited Bennu to map the surface and find a good landing spot to obtain samples. In October 2020, OSIRIS-REx touched down on the asteroid, procured a sample, and prepared it for delivery to Earth. In May 2021, the spacecraft departed from Bennu and is expected to arrive back home in September 2023. Scientists will then study this very expensive rock sample, searching for signs of alien life.

Astrobiologists are hopeful that Enceladus and Europa, moons of Saturn and Jupiter respectively, might support some form of life now or in the past. The new James Webb Space Telescope (JWST) is also involved in the search for alien life. It can detect “biosignatures” around exoplanets, planets outside of our solar system. In all these ways, NASA is searching for signs of alien life in the universe.

Heather Graham, a NASA astrobiologist at the Goddard Space Flight Center in Maryland, says, “We don’t actually know yet how life on this planet began….” Of course, NASA is looking for some natural explanation of how life began. Graham further said that we must “roll back that clock to see how life began.” Why not roll back the clock all the way to the beginning? Science can’t explain how the universe began. Not very long ago, scientists thought the universe was eternal, and they made fun of the idea that the universe had a beginning. However, they reluctantly had to admit that the evidence shows there was a beginning, as Genesis has said for thousands of years.

Perhaps some are motivated to search for signs of alien life to show that God is unnecessary. Will science someday find that there is life, even microbial life, elsewhere in the universe? Perhaps, but if there is, God created it since He created the universe.

Matter Greatly Exceeds Antimatter

It’s “one of the Universe’s best-kept secrets” and a mystery that physicists are working to resolve. Every subatomic particle in the universe has an antimatter equivalent. Each atom consists of electrons, protons, and neutrons. The negative electrons have alternative positrons with a positive charge. If you could combine an electron and a positron, they would cancel each other. Protons and neutrons, which compose the nucleus of atoms, are made of smaller particles called quarks. There are also anti-quarks, and if you combined a quark and an anti-quark, they would explode and destroy each other. Our universe, and us, can only exist because matter greatly exceeds antimatter.

If matter and antimatter were in a state of symmetry with equal amounts, they would have destroyed each other, and nothing would exist. Scientists theorize that the creation event, or Big Bang, should have created an equal amount of matter and antimatter, so they wonder why the lack of symmetry. In other words, why does anything exist in the universe, our planet, and our bodies? The universe is made of matter, while antimatter is almost non-existent except in radioactive particle decay and particle colliders such as the Large Hadron Collider (LHC) in Switzerland and France.

According to the Standard Model of particle physics, physicists theorize that a “charge-conjugation parity violation” (CP) caused the lack of symmetry – but how and why? Physicists working with the LHC say particles and antiparticles can spontaneously transform from one to the other. LHC spokesperson Chris Parkes said, “Through more precise measurement, large improvements have been made in our knowledge. These are key parameters that aid our search for unknown effects from beyond our current theory.”

We can be thankful that in today’s universe, the amount of matter greatly exceeds antimatter. Since physicists are looking for an explanation, they may eventually solve the mystery. It will be interesting to see the scientific explanation for the lack of symmetry. Whatever process scientists discover, we suggest that this is another example where intelligence and wisdom provide a more reasonable ultimate explanation than accidental chance offers.

Beauty in the Natural World

Everywhere we look, we see beauty in the natural world. One example of that is Wilson’s bird-of-paradise (Cicinnurus respublica). This unique and exotic bird displays extravagant plumes and feathers that capture attention.

Males are more brightly colored than females. They have a black head with a turquoise crown and yellow feathers on the nape of the neck. Their iridescent tail feathers form the shape of a handlebar mustache. These birds flash and shimmer their colors in the gloom of the forest floor only on two islands in Indonesia.

The most fascinating behavior of Wilson’s bird-of-paradise is the vivid and complex dance males perform to entice females. Because his movements are so robust that he needs an open space free of clutter, he first crafts his “dance floor.” To prepare the dancing area, the bird clears the ground of leaves and other obstacles that could disrupt his performance. Scientists have tested this behavior by placing leaves in front of the bird. That obstruction provoked the bird, causing him to immediately clear the leaves from the area.

A female will find a perching spot on a branch to watch the show from above. As the male dances, she examines every detail of his routine to decide whether to choose him as a mate. Wilson’s bird of paradise females are very critical performance judges.

The dancing ability and intelligence of these birds are astonishing. Wilson’s bird-of-paradise is only one of God’s many beautiful and fascinating species. You can read about more of them at THIS LINK. Beauty in the natural world is difficult to explain by naturalistic evolution since, in many cases, the beauty has no survival value. However, a creative Designer who loves beauty would certainly create a beautiful world and give humans, created in His image, the ability to enjoy and be inspired by beauty in the natural world.

Convergent Evolution and Carcinization

When unrelated species of animals or plants have common features, evolutionary biologists call it “convergent evolution.” There are many examples, such as:
* Dolphins and bats use echolocation to find food.
* Titan arum and rafflesia plants use putrid odor to attract pollinators.
* Nightingales and humpback whales sing similar songs just for beauty.

Those are only a few of the vast number of examples that scientists explain as convergent evolution. You can probably think of others. For example, bats, birds, and insects all have wings, but they are not related. In addition, unrelated venomous or poisonous creatures often wear bright colors as a warning, for example, snakes, frogs, and insects. Usually, the convergent features of various animals and plants serve an obvious purpose for the species’ survival.

Perhaps the most repeated convergence appears in the crab-like body shape. A crab has a flat, rounded shell and a tail that tucks under its body. Evolutionary biologists say that body plan has “evolved” at least five times. Scientists even have a name for this phenomenon. They call it “carcinization,” but they can only guess why it happened.

The result of carcinization is that many unrelated crustaceans resemble crabs. As a result, we often call them crabs even though they are not true crabs. A familiar example is the so-called king crab. Crab-shaped animals come in a wide range of sizes and live in various habitats, from the oceans to the mountains. So, with these creatures living in diverse ecosystems, scientists have difficulty explaining why they evolved the same body plan. Some suggestions include the tucked-under tail providing greater safety from predators or the body shape allowing them to move sideways.

We have a suggestion of why the crab shape, or carcinization, shows up in so many different crustaceans. Rather than convergent evolution, the common traits can be explained by a common Creator. That would explain why these creatures have the DNA building blocks for crabbiness – oops, I mean crab body shape.

Owls Are Essential in God’s System of Life

Owls are some of the world’s most interesting creatures. There are some 250 owl species living on every continent except Antarctica. People have associated owls with wisdom, mythical guidance, protection, and even death. The truth is that owls are essential in God’s system of life. Here are four interesting facts about owls:

#1. OWLS CAN TURN THEIR HEADS 270 DEGREES. Johns Hopkins researchers discovered that owls have a reservoir under their jaw to prevent the blood supply to their brains from being cut off when they rotate their heads. They also have extra neck vertebrae allowing them to turn their heads to that extreme angle.

#2. OWLS CANNOT MOVE THEIR EYES. Owl eyes make up 5% of the animal’s body weight, while human eyes make up .0003% of our body weight. Their huge eyes have pupils that can dilate extra wide and a reflective layer at the back of their eyes to give them exceptional night vision. In addition, their eyes are designed to provide them with binocular vision, giving them excellent depth perception and the ability to judge distances.

#3. OWLS HAVE HEARING THAT ALLOWS TRIANGULATION. Some owls have asymmetrically arranged ears, with one slightly higher than the other. That allows them to judge the direction of sound vertically as well as left to right. For example, sound from a rodent will reach one ear sooner than the other, and the owl uses this difference to triangulate the distance to the source of the sound, even if under snow or leaf piles.

#4. OWLS HAVE SOUND BAFFLES ON THEIR WINGS. The feathers on the leading edges of their wings have comblike structures that dampen air turbulence and eliminate the “whooshing” noise in flight. They also have finer feathers on the top and trailing edges of their wings to break up the sound. These features allow almost silent flight when hunting prey. Engineers have copied this design to build quieter aircraft and drones.

Owls are essential in God’s system of life to control rodent populations. Most of us are unaware of the great service they provide because they carry out most of their activity at night. Owls are an excellent example of the specialized design God built into the creation to make planet Earth suitable for human habitation. No other land animal demonstrates all of these unique characteristics making chance evolutionary theories difficult to support. Indeed “we can know there is a God through the things He has made” (Romans 1:20).
