The Biblical Flood Story

We received a question about kangaroos on Noah’s ark. I want to share my response here because others probably have similar questions about the biblical flood story.

I think there were no kangaroos on the ark. Let me explain. The biblical evidence indicates that the flood was universal, covering the populated Earth, but not global, covering the entire globe. “The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time” (Genesis 6:5). For that reason, God decided to send a flood to destroy the evil people, but He spared Noah and his family.

God would have had no reason to flood Australia, the North and South Poles, or the top of Mount Everest, because no people lived there. You can read the biblical flood story in Genesis chapters 6-8. After the flood, Genesis 9 tells us that God made a covenant with Noah and promised, “never again will there be a flood to destroy the earth” (verse 11). Noah’s obligation in this covenant is summarized in Genesis 9:7: “As for you, be fruitful and increase in number; multiply on the earth and increase upon it.”

Noah’s descendants failed to carry out their obligation in the covenant. Genesis 11 shows that they went only to the plain of Babylon (Shinar) and devised a plan to glorify themselves instead of obeying God’s instructions. “Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves and not be scattered over the face of the whole earth” (Genesis 11:4).

Because of their defiance, God was forced to find a solution while keeping His promise to never again destroy the human population with a flood. Instead, God confounded them with different languages, ending their plans and causing them to follow His instructions by scattering them “over the face of the whole earth” (Genesis 11:9).

When you examine the biblical flood story, you can see that God had no reason to flood the entire globe, since humans were limited to a relatively small geographical area. Then why does God say in Genesis 6:17, “I am going to bring floodwaters on the earth to destroy all life under the heavens, every creature that has the breath of life in it. Everything on earth” will perish.” He does not mean every creature literally, because He commanded Noah, “You are to bring into the ark two of all living creatures, male and female, to keep them alive with you” (Genesis 6:19). He also did not refer to every fish and sea creature. He told Noah to take seven (or seven pairs) of every kind of clean animal (Genesis 7:2) so they could be used as sacrifices to God after the flood, as we see in Genesis 8:20.

There would not have been enough water on Earth to cover the entire globe above the height of Mount Everest. There was no need to flood areas where n o humans lived or to kill all the animals on the planet. Then why do cultures around the world have flood legends? Every person on Earth is descended from the family that survived the flood, so the story has been passed down in every culture, with modifications. The biblical flood story is the accurate account of the event that changed the entire world. In His mercy, after the flood, God gave humanity another chance while keeping His promise. He scattered the people around the globe by confounding their languages, preventing a corrupt one-world government.

Even today, God in His mercy offers each person on Earth a second chance through the sacrifice of God’s only Son. (See John 3:16-17.) Be wise and don’t pass up the grace God offers.

The Pale Blue Dot

The picture above is the “Pale Blue Dot” photograph, taken by the Voyager 1 spacecraft on Valentine’s Day, February 14, 1990. At the time, Voyager 1 was 3.8 billion miles (6 billion km) from Earth and moving away. The camera was about to be shut down to save power, since it was not going to fly close to any planet as it was leaving the solar system. Before shutdown, the mission commander ordered the probe to take 60 images to form a “Family Portrait of the Solar System.” Thirty-four minutes after it took this picture, the camera was shut down forever. In the picture, the Sun is below, and the pale blue dot you can barely see in a sunbeam is planet Earth.

This year, prominent atheists became upset by astronaut Victor Glover’s words aboard Artemis 2 during its historic trip around the Moon. Some even expressed concern about the “separation of church and space.” However, when he spoke from space, he seemed to receive approval from the other astronauts, but not from atheists on the ground. Some of Glover’s words that apparently upset atheists include, “You’re on a spaceship called Earth that was created to give us a place to live in the universe. You are special. In all of this emptiness, this is a whole bunch of nothing, this thing we call the universe, you have this oasis, this beautiful place that we get to exist together.” The pale blue dot is not insignificant.

Why should those words distress anyone? Many early scientists explored creation because they believed in an orderly universe created by an intelligent God. Many astronauts have said that being in space gave them a spiritual experience as they realized that Earth reveals design and purpose. Many leading science popularizers have tried to tell us that science destroys Christian belief. Richard Dawkins, Bill Nye, Michael Shermer, Lawrence Krauss, and others have written popular books arguing that science makes belief in God unnecessary and implausible. The truth is that scientific discoveries continue to support belief in God and challenge atheism.

Astronomer Carl Sagan was partially responsible for the picture of the pale blue dot, and he popularized the term in his book by the same name. He wrote, “Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all its vastness, there is no hint that help will come from elsewhere to save us from ourselves.” He also said that Earth is such a tiny pale blue dot in the universe that it shows we have no privileged position in the cosmos. Sagan was a brilliant man, but he overlooked the fact that Someone did come from elsewhere to save us. Victor Glover knows that is true. He said that we are not a lonely cosmic accident, but instead, we are loved, and those who believe in Jesus Christ agree.

Genetic Evolution Is Not the Answer

God told Noah and his sons: “…BE FRUITFUL AND INCREASE IN NUMBER; MULTIPLY ON THE EARTH AND INCREASE UPON IT” (Genesis 9:7). Scientists who study genetics tell us that this command is impossible by genetic evolution alone. When evolutionary anthropologists calculate how long it would take for humans to spread throughout the planet by genetic evolution, they find it would require at least 88 million years. No one believes that humans have existed on Earth for that long, so genetic evolution is not the answer.

Humans occupy as much of the planet’s dry land as all other mammals combined. Evolutionists attempt to solve this problem by saying it is due to “cultural evolution,” meaning that as cultures evolve, humans find ways to adapt to new environments.

Since genetic evolution is not the answer, a biblically sound approach is to accept that a combination of social cooperation, language, creativity, and intellect allowed humans to cover the planet many times faster than would be possible by genetic evolution. We can credit that to God creating humans in His image with those abilities.

The spread of humans over the entire planet is due to the way God created us, and is not an accident. The bigger issue now is how we can control our numbers and efficiently use the resources for survival that God has made available on Earth.

The Magnetic Mystery of Bird Migration

Scientists have known for decades that birds use Earth’s magnetic field to guide their migrations, but how they detect it has been a mystery. A recent German study published in the journal Science offers insight into this magnetic mystery of bird navigation.

Birds, as well as other animals, have immune cells called macrophages in their livers. Among other duties, these macrophages eliminate old red blood cells. As they digest these no-longer-needed red blood cells, they accumulate iron nanoparticles, making the macrophages superparamagnetic. In other words, they can detect Earth’s magnetic field as the bird passes through it.

To test whether these magnetic macrophages help birds navigate, the researchers used homing pigeons trained to fly 12.4 miles to their aviary. Pigeons without macrophages reached the aviary when the Sun was unobscured, but they got lost when the weather was overcast. This suggests that the birds use Earth’s magnetic field as well as the Sun to guide their flight. Using electron microscopy, the researchers observed that the macrophages were in contact with nerve cells, which could transmit magnetic information directly to the bird’s brain.

Solving the magnetic mystery of bird navigation can explain how birds that migrate at night find their way when the sky is overcast. It may also explain how sharks navigate and how bats migrate in the dark. Birds and other migrators use vision, magnetism, and other methods to find their way. God has designed into living things the features they need to survive.

Africa’s Massive Size

How big is Africa? With Africa’s massive size, you could overlay the United States, China, India, Eastern Europe, Italy, Switzerland, Germany, France, the Netherlands, Belgium, Spain, Portugal, and Japan on top of Africa with no overlap among the countries.

Many misunderstandings stem from the way maps are drawn. Mercator maps, which we are familiar with, show the United States as a very large landmass, and we know it has many natural resources. How blessed Africa is in terms of natural resources remains unknown because of Africa’s huge size and human exploitation. Wars have been fought over much smaller areas of land.

The implications of Africa’s massive size are enormous, with the greatest being an abundance of natural resources along with an abundance of people who need to hear the Gospel. Nearly every element necessary for technology can be found in Africa. However, the exploitation of the people in Africa has prevented the extraction of most of these resources, and many are still unexplored. Human greed has prevented us from using the abundant resources God has provided, but the problem all begins with the exploitation of other humans.

Humans Are Viruses on the Earth – or Not

Humans Are Viruses on the Earth – Influenza Virus — Influenza virus 3D illustration

Perhaps you have seen posts or comments online claiming that humans are viruses on the Earth. The argument is that human numbers are growing, and we “feed parasitically on the body of the Earth.” They say we are swarming over the Earth and leaving no part of the planet “untouched by our pollution and destruction.”

The mantra is that humans move into an area, multiply until they consume all the natural resources, then move on to another area, like a virus. Critics suggest that all other mammals live in equilibrium with their surroundings, whereas humans behave like viruses that spread and consume resources. So the question they ask is whether humans are a disease, a cancer, or a virus on the Earth, what are we going to do about it? How can we stop this human virus?

As Christians, we believe that humans were made in God’s image and that God entrusted the first humans and us with taking care of the planet and ruling over it (see Genesis 1:28). Perhaps we’ve done a better job of ruling over the planet than of taking care of it. Some have pointed out that even though the Bible says we were created in God’s image, we are also the ones who introduced sin into the world.

Hosea 4:1-3 is a Bible passage sometimes quoted by those who insist that humans are viruses on the Earth. In this passage, Hosea tells the children of Israel that because they have been swearing, lying, killing, stealing, and committing adultery, God will punish them by allowing them to waste away along with the animals, birds, and fish. You could say that applies to us today, but that might be stretching the context.

It is true that God gave humans the job of being stewards of the Earth, to rule over and protect or conserve the creatures that live here. It is also true that we have often failed in that job, but God always gives us another chance to do better. As for humans introducing sin into the world, God also gave us a second chance on that. The most amazing thing we read in the Bible is that God became a human being to live a perfect life, to show us what that is like, and to bear the punishment for our failures.

As we consider whether humans are viruses on the Earth, we must consider our relationship with the Creator. Perhaps if we can accept what God has done through Jesus Christ to restore us to a right relationship with Him, we will find that we can have a right relationship with the Earth God gave us to live on. Remember that God is the giver of every good and perfect gift (James 1:17).

Two Views of the Universe

Prominent atheists recently became upset by Victor Glover’s words aboard Artemis 2 during its history-making trip around the Moon. Some even expressed concern about the “separation of church and space.” We have written before about Victor Glover and his status as a Bible-believing Christian. When he spoke from space, he seemed to receive approval from the other astronauts, but not from atheists on the ground. We see the contrast between the two views of the universe.

Some of Glover’s words that apparently upset atheists include, “You’re on a spaceship called Earth that was created to give us a place to live in the universe…You are special. In all of this emptiness, this is a whole bunch of nothing, this thing we call the universe, you have this oasis, this beautiful place that we get to exist together…” Why should those words distress anyone?

Historically, many early scientists explored creation because they believed in an orderly universe created by an intelligent God. Many astronauts have said that being in space gave them a spiritual experience as they realized that Earth reveals design and purpose. I remember watching the Apollo 8 crew read from the book of Genesis on Christmas Day in 1968 as they traveled around the Moon. Our present NASA administrator, Jared Isaacman, said that his time in space convinced him that “the heavens declare the glory of God.”

Many leading science popularizers have tried to tell us that science destroys Christian belief. Richard Dawkins, Bill Nye, Michael Shermer, Lawrence Krauss, and others have written popular books arguing that science makes belief in God unnecessary and implausible. The two views of the universe can’t both be correct. The truth is that scientific discoveries continue to support belief in God and challenge the atheist concept.

Years ago, Carl Sagan said that Earth is such a tiny dot in the universe that it shows we have no privileged position in the cosmos. Victor Glover said that we are not a lonely cosmic accident, but instead, we are loved. On April 30, 2026, the movie “The Story of Everything” will open in select theaters nationwide. It will compare the two views of the universe—the atheist view and the biblical view that God designed and created all things and that He loves us. I think the movie will show that God’s story is the best and that it is actually supported by science.

The Moon’s Gravity Affects Earth

As I write this, Earth’s gravity is pulling the Artemis 2 and its four astronauts back toward home after completing a trip around the Moon. Gravity is one of the precisely tuned forces that make life possible. It also explains why the Moon doesn’t fly off into space. Earth’s gravity influences the Moon, and the Moon’s gravity affects Earth in several ways.

One way our planet is affected by the Moon’s gravity is through the tidal lock that causes the same side of the Moon to always be visible from Earth. The Artemis 2 crew had the rare privilege of seeing the far side of the Moon as they passed around it. I’ve heard some newscasters call it the “dark side of the Moon,” but the Moon has no dark side. The Sun’s illumination reaches all sides of the Moon as it orbits our planet.

The Moon’s gravity influences Earth by CAUSING THE OCEAN TIDES. Once, it even HELPED OPEN THE SUEZ CANAL. God’s finely tuned design of the Earth-Moon system allows us to exist on this planet.

How Many Moons in Our Solar System?

As I write this, four Artemis 2 astronauts are on their way back to Earth after making a trip around the Moon. Until they make their planned splashdown in the Pacific Ocean near San Diego, California, on Friday, April 10, 2026, I want to look back at what we’ve written about our amazing natural satellite. Our Moon is very unique—unlike any other moon—in both size and number. There are how many moons in our solar system? You can see from THIS ARTICLE that the number of confirmed moons keeps changing.

Will the number of confirmed moons change again in the future? Probably, but we know that Earth has only one Moon, and it is just the right SIZE and MASS.

So, there are how many moons in our solar system? If you count all the moons orbiting the planets, the total is approximately 430. That number is subject to change, but there is only one that is just right, and I am sure God designed it that way.

The Benefits of Sunlight

It’s springtime, and one of the great things about this season is that it gives us more daylight hours. The benefits of sunlight and its warmth help plants grow, making everything feel new. In Genesis 1:14, we read that God cleared the air to make the lights in the sky visible, so they could separate day from night and serve as signs for seasons, days, and years. Animals rely on the Sun, Moon, and stars to know when to breed and when and how to migrate. Plants need sunlight for photosynthesis, which produces oxygen that humans and animals need.

The benefits of sunlight include both our physical and mental health. Sunlight regulates our circadian rhythm, the biological clock that controls sleep, appetite, and hormone production. Daylight boosts serotonin levels, signaling it’s time to wake up. Spending time outside in the sunlight helps our bodies produce vitamin D, which may help protect against dementia, type 2 diabetes, and other chronic illnesses.

After a long, dark winter, going outside to enjoy the sunshine and fresh air makes us feel refreshed. Even sitting near a window with sunlight streaming in improves our mood. Light therapy is sometimes used to treat depression, especially seasonal depression during the winter months. While we consider the benefits of sunlight, we need to remember that excessive direct exposure to ultraviolet light can lead to skin cancer, cataracts, and macular degeneration.

Genesis 1:15 states that the “lights in the expanse of the sky” were meant to “give light on the earth.” John 1:4-5 tells us Jesus came to bring true light to the world. We could not live without the benefits of sunlight, and I wouldn’t want to live in a world without Jesus, who came to bring us light and life. John also reminds us that Jesus created the light and everything else that exists. (See John 1:1-14.)
