Deserts, Oceans, and Life

Deserts, Oceans, and LifeHave you ever been in a desert for an extended time? Have you ever taken the sand of a desert and looked at it under a microscope? Have you visited the Great Salt Lake or the Dead Sea? Do you feel that deserts are a wasteland? Science has come to understand something about deserts, oceans, and life that shows wisdom and planning that is beyond our wildest dreams.

We now know that deserts, in general, are dried up lakes. The vast Death Valley desert in the United States (pictured) was a lake at one time. So was the Atacama Desert in Chile, which is now called “the driest place on Earth.” The African Sahara was once the largest lake on Earth called the Mega Chad. Fossil hunting in these deserts reveals the remains of fish and plankton called diatomite. Diatomite is the skeletal remains of microscopic forms of life called diatoms. The skeletons are composed of silicon dioxide, which is a very durable substance and is highly porous and lightweight. These factors make it ideal for the wind to carry. Diatomite also contains phosphorous, which is essential for life to exist. Every living cell needs water and phosphorous, which is the second most abundant mineral in our bodies.

To have rain on the Earth requires water vapor, cool temperatures, and condensation nuclei on which the water can condense. When bodies of water become deserts, the dust contains phosphorus. Wind currents of our planet take the dust from deserts which once were lakes and carry it vast distances. Dust particles become the nuclei for condensation of raindrops that carry water and nutrients to the ground. The deserts of the Sahara maintain life in the Amazon basin. Lightning in the storms produces nitrogen to add to the nutrients. This pattern is repeated in every life-filled system on Earth. The Great Plains of the United States are sustained by the dust and minerals of the Mojave Desert, an old inland sea.

The Bible refers to all of this in passages like Isaiah 50:2 and Job 38:37-38. It is not the purpose of these passages to reveal the complex system that produces the water and nutrients for life to exist. However, the references to the dust and the drying of the sea make it clear that the ultimate Author of the scriptures knew the processes used to supply a planet uniquely designed to harbor life. Deserts, oceans, and life speak to the design built into the Earth. They also show us that God has given us what we need for life and the scriptures to provide a reliable guide for living.

Chemistry of Water Is Essential to Life

Chemistry of Water Is Essential to LifeThere are many “pop-science” articles showing up in the media, suggesting that life on planet Earth is not unique. They are suggesting that there may be other chemistries with different molecular structures elsewhere in the cosmos. The truth is that the chemistry of water is essential to life.

The key to this question is a basic chemistry issue involving the water molecule. We have posted previously on the nature of the water molecule. You can also access articles from our printed publications by using the search engine on doesgodexist.org.

The main point is that the water molecule is polar. The bonding positions on the oxygen atoms in water are 105 degrees apart. Because of that, the two hydrogen atoms that bond with the oxygen atom are on one end of the molecule and oxygen is on the other end. That makes the water molecule polar, and it gives water unique properties, including the ability to dissolve most inorganic compounds.

Discover magazine (July/August 2019, page 82) carried an excellent explanation of why the chemistry of water is essential to life, making it possible for life to exist. Here is a quote from the article:

“For the chemical processes of life to happen, molecules must be able to connect, separate, and reconnect in specific ways. Think about DNA replication, for instance. The base pairs that make up the genetic code bond when their negatively charged hydrogen atoms are attracted to positively charged atoms in another nucleotide. Those bonds hold the two strands of the double helix together, but because hydrogen in water molecules also bond this way, it’s relatively easy for enzymes to ‘unzip’ the double helix for replication, then bind the two new strands together again. However, the molecules of life won’t work in hydrocarbons the way they do in water. That’s because most hydrocarbons don’t tend to form hydrogen bonds.”

In Genesis 1:2, the very first action of God on the newly created Earth is that His “Spirit moved on the face of the waters.” In Proverbs 8, wisdom speaks of the fact that in the creation process there was a time when there was no liquid water (Verse 24). We are finding water scattered throughout the cosmos, and it has become pretty apparent that water was a created and carefully designed tool to allow the basics of life. The chemistry of water is essential to life.

In baptism, we see water having a spiritual significance as well. Water is essential to much of God’s plan and compelling evidence of His wisdom and design in all areas of our existence.

Alien Life Without Water

Is Alien Life Without Water Possible?
For all of my life, there have been articles, videos, and public presentations claiming that there must be life elsewhere in the universe. Now that we know there are thousands of planets in the creation, we see attempts to maintain that with so many planets there must be life somewhere. Scientists are even speculating alien life without water.

We need to remember that the Bible doesn’t say that this is the only planet where God created life, so this is not a biblical issue. The latest attempts to expand the window of what life is has rejuvenated the need to show the design built into the development of life. Life on Earth is based on carbon, hydrogen, oxygen, and nitrogen. The National Science Foundation has just funded a three-year program at Saint Louis University to explore what building blocks might be used to make a different kind of life. The chemicals they are considering are hexane, ethers, and chloroform. There is particular interest in whether these materials can form membranes that could be considered life.

The first problem is the definition of life. Life has traditionally been defined as “that which can move, breathe, respond to outside stimuli and reproduce.” An extraordinary chemistry is necessary to meet all of these criteria. Water is the basic substance of life on Earth. The water molecule is polar, meaning that one end of the molecule is negative and the other end is positive. Oxygen is the negative end. Oxygen’s bonding orbitals allow the attachment of two hydrogen atoms making that end positive. This polarity allows water to dissolve other molecules. Salt, for example, is made up of sodium which is positive and chlorine which is negative. When you put salt in water, the sodium is attracted to the oxygen end of the water molecule, and the chlorine is attracted to the hydrogen end of the molecule because unlike charges attract each other. This pulls the salt molecule apart and allows the salt to dissolve. Alien life without water seems impossible.

Hydrocarbons like methane have four hydrogen atoms attached to the carbon atom symmetrically. That makes the molecule non-polar and unable to dissolve salt. Numerous experiments are underway to circumvent this problem including the use of vinyl cyanide (also called acrylonitrile) which has been found in the atmosphere of Saturn’s moon Titan. Coming up with a formula for alien life without water will be difficult. How a substitute for oxidation would work has not even been publicized, so respiration would be an equally great challenge.

Chris Butch, a chemist of the Earth Life Institute, says “It’s like trying to build a car in your backyard out of lawnmower parts, versus having the Maserati factory build a supercar.” As science looks for something that can be called life elsewhere in the solar system, we should be impressed with the wisdom involved in the original building of life on planet Earth.

Life Chemical Factory on Enceladus?

Life Chemical Factory on Enceladus
The picture shows Saturn’s moon Enceladus with Saturn in the background and part of a ring visible. Scientists are talking about a life chemical factory on Enceladus. One of the interesting questions about the origin of life is the question of how the chemicals needed to produce life came into existence.

Many believers in God answer that question just saying “God created them” and leaving it at that. For many of us with interest in science, that question expands to trying to understand HOW God created those chemicals. Saying that He spoke them into existence may be theologically acceptable, but the evidence shows that God used processes that we can understand.

Enceladus is essentially a vast ocean of water surrounded by a massive layer of ice. Scientists believe that powerful hydrothermal vents mix up the material found in the moon’s porous core with the salt water that makes up its vast ocean. This material is then ejected out into space in the form of enormous plumes of water vapor and ice granules you can see in the picture taken by the Cassini spacecraft. The sight is quite spectacular, and it was into one of these plumes that NASA’s scientists were able to send Cassini to examine their composition.

What the scientists learned is that the plumes contain organic materials. These are materials that are part of the building blocks of life. Therefore, this moon seems to be a factory that builds several of the ingredients needed to produce life.

Think of how factories produce cars. Factories at different locations all over the country build the parts. The parts come together in one place where highly skilled and creative engineers assemble them into a working automobile. In the same way, we can see a possible life chemical factory on Enceladus.

The more we explore space, the more we understand why these “factories” exist and how they have been used by “the great Engineer” to produce life on Earth.

Electrons Are Essential for Life

Electrons Are Essential in the Elements of Life
Everyone knows that electrons allow us to have computers and other electrical devices, but you may not realize how many ways electrons are essential. The mass, charge, magnetic properties, and spin of electrons are all designed to make life possible. It is amazing that something far too small for us to see is so important.

The changing momentum of electrons creates light which is essential for life. Electrons are also the fundamental cause of all that happens in chemistry. Atoms bond with other atoms to make molecules by exchanging or by sharing electrons. The complex organic molecules in your body, including DNA, are held together by electrons. The properties of every element in the universe are determined by how its electrons are arranged around the nucleus.

The oxygen atom with eight electrons joins with two single-electron hydrogen atoms to form water. The arrangement of the electrons in the oxygen atom causes the oxygen/hydrogen union to form in a way that gives water its unusual properties. The arrangement of electrons and the way the atoms bond causes water to dissolve salts, freeze from the top down, form crystals when freezing, and have surface tension. Without these unique properties of water, life would not be possible on Earth.

The arrangement of the six electrons in the carbon atom allows it to form enormous numbers of carbon compounds in various patterns. Because carbon can build so many organic compounds, our carbon-based life can exist. Without the particular arrangement of electrons in oxygen and carbon, life would not be possible.

Add to carbon and oxygen more than 90 other elements and their electron arrangements, and you can see that the probability of all of this happening by chance is not reasonable. We can be sure that a Master Designer created this complex system in which electrons are essential.

Life Needs Phosphorus

Life Needs Phosphorus
The element phosphorus is used to make matches. Molecular phosphorus has two common forms. There is white phosphorus which is dangerously combustible and is used to make fireworks and weapons. The more stable red phosphorus is used on the side of any box of safety matches. When you strike the match against the red phosphorus, a small amount of it is changed to white phosphorus to ignite the match. But phosphorus has more important uses than starting fires. Life needs phosphorus. The average human body contains about 26.5 ounces (750 grams) of phosphorus. Most of it is in our bones.

Phosphate is a compound of phosphorus and oxygen. It combines with sugars in living tissue to form the backbone of DNA, which is the blueprint for life found in every living cell. Phosphate is also part of a complex organic chemical called adenosine triphosphate (ATP) found in every living organism. ATP releases energy so that cells can function. Life needs phosphorus and could not exist without it in an abundant supply.

Recent research presented at the European Week of Astronomy and Space Science on April 5, 2018, indicates that phosphorus may not be widely available in the Milky Way. The research indicates that it is more random than scientists had previously thought. That means even if one of the recently discovered exoplanets had all of the conditions required to support life, it still might be lifeless without phosphorus.

We have often referred to the many conditions required to make a habitable planet. Here is one more to add to the list. Life needs phosphorus, and apparently phosphorus is less widely distributed than we thought. Phil Cigan, one of the astronomers involved in the study, said, “It’s not a guaranteed thing to have phosphorus abundant everywhere, ripe for the picking. It seems to look like luck plays a bigger role in this.”

Is it just one more chance coincidence that planet Earth has the phosphorus needed for life? We don’t think it is a matter of luck. We think this is another evidence of God’s design for life.
