Major Factors for Rejecting Faith in God

Polls show that belief in God among Americans has declined over the past few years, and most dramatically among Gen-Zers. Generation Z is the term used to describe those born between the late 1990s and early 2000s (approximately 1997 to 2012). This generation grew up with access to the internet and portable digital technology. What are some major factors for rejecting faith in God?

Stephen C. Meyer said that the Discovery Institute surveyed people if they agreed with this statement: “The findings of science make the existence of God less probable.” Among self-proclaimed atheists, 65% agreed, and 43% of agnostics agreed. What these people perceive about science has influenced their belief in God. However, as we have said before, science supports faith in God.

In recent years, scientific discoveries have given us more reasons to believe in God. One significant discovery is that the material universe had a beginning. Evidence for that appeared in the 1920s, was confirmed in the 1960s, and further reinforced in the 21st century. The Bible tells us that in verse 1, but it took scientists years to accept the evidence. Anything that begins to exist must have a cause. The cause of the material universe must be outside of time and space and, therefore, immaterial. Science recognizes that time, space, matter, and energy all had a beginning, but they could not have created themselves.

A second discovery that points to an intelligent Creator is that the universe was fine-tuned for life from the beginning. Many physical constants must be precisely as they are for life to exist. More than that, without precision fine-tuning of the physical laws and constants, the universe itself would not exist. Chance cannot explain the precision because so many precise factors must work together.

A third discovery that came into a fuller understanding in the 21st century is the design of the digital code in the DNA molecule that makes life possible. This design has been there since the emergence of the first living cell. We have no examples of information being created without a mind to create it. Information does not happen by chance.

In those three recent discoveries, science rediscovers God. Then what are the major factors for rejecting faith in God? More on that tomorrow.

No Life Without Water

Without water, life would not be possible. For that reason, astronomers are constantly looking for other locations in the universe where liquid water might exist. Only in such places could there be any hope of finding life. Whether life exists anywhere in the universe outside of planet Earth is a question people have asked for hundreds of years. Scientists still don’t know the answer, but everyone agrees that there could be no life without water.

The water molecule seems very simple. It is H²O–one oxygen atom combined with two hydrogen atoms. However, instead of bonding in a straight line (H-O-H), the two hydrogen atoms are on one side of the water molecule at a 104.5-degree angle from each other. That alignment gives the hydrogen side of the water molecule a partial positive charge, while the other side has a partial negative charge. Because of that, the positive and negative sides of water molecules attract one another and form hydrogen bonds resulting in a network of water molecules.

When water is in the gaseous state, the interaction between molecules is negligible. However, when it is in the solid form of ice, each water molecule forms a bond with four others, creating a lattice that causes ice to be lighter than liquid water. For most substances, the solid state is heavier than the liquid state. This unique property of water causes ice to float. Additionally, the low thermal conductivity of ice prevents the water below from freezing. If lakes and oceans froze from the bottom up, it would kill all marine life and ultimately all life on Earth.

If water molecules did not form hydrogen bonds, instead of boiling at 100 degrees C, water would boil at -100 degrees C. That would prevent life processes. Furthermore, because there is a 100 degree C difference between water’s melting and boiling points, life is possible in Earth’s wide range of environments. Water has the highest heat of evaporation of any known substance so that it remains liquid up to and even at its boiling point. It also has the second-highest heat capacity of any known substance, allowing its temperature to remain stable during heat fluctuations in the environment. Those qualities of water are also critical for life, meaning that there could be no life without water.

Water’s ability as a solvent makes it essential for the life processes of living cells. Likewise, water’s inability to dissolve oily substances is vital to create a strong “hydophobic effect.” Cell membranes, DNA, RNA, and proteins all contain oil-like regions. If the water in the cells could dissolve them, life would not be possible. In addition, the water molecule can participate in and enable chemical processes such as hydrolysis, reduction, oxidation, and others that are essential in living cells.

The bottom line is that there is no life without water and the fine-tuning of the hydrogen bonding in water molecules. With new scientific discoveries, we see fine-tuning for life in the cosmos and even in the cells of our bodies. Without that fine-tuning, life would not exist, and we would not be here. Accidental coincidences do not explain such incredible precision of design. We think the explanation goes beyond science and points to an intelligent Designer.

The Atmosphere Is Fine-Tuned for Life

Nitrogen and oxygen together make up about 99% of the air we breathe. The vast majority of our atmosphere is nitrogen. Oxygen is ten times as abundant as nitrogen in the universe, but it makes up only about 21 percent of our atmosphere. So, the less common element is the most abundant in our atmosphere. What does that mean to us? The bottom line is that the atmosphere is fine-tuned for life. Let’s examine that more carefully.

An atom of oxygen and an atom of nitrogen differ by only one proton and one electron. That may not seem like much, but it makes a world of difference. Both of those elements form diatomic molecules, meaning that two atoms bond together to make one molecule of oxygen or nitrogen.

Covalent bonding is the chemical bonding of atoms by equal sharing of electrons. That bond gives atoms stability in their outer, or valence, electron shells. Atomic stability requires eight valence electrons. The only elements with that number are the so-called “noble gases”–helium, neon, argon, krypton, and radon. For that reason, they are inert, refusing to combine with other elements. All other elements need electrons to complete the octet in their valence shells.

An oxygen atom has six electrons in its valence shell, so it needs to share two electrons to become stable. When an oxygen atom shares two electrons with another oxygen atom, they both become stable. Nitrogen, on the other hand, has only five valence electrons. Therefore, by forming a covalent bond with another nitrogen atom, sharing three electrons, both atoms complete their outer shell. In this way, our atmosphere is made up of stable diatomic oxygen and nitrogen molecules.

However, not all molecules are equally stable. That is where we see the atmosphere is fine-tuned for life. For example, oxygen molecules have a double bond sharing two electrons, but nitrogen atoms have a triple bond sharing three electrons for more stability. That difference may seem insignificant, but it is essential to make life possible. Come back tomorrow when we will explain what a difference it makes.

How The Sun Works

We depend on the Sun every day to generate the energy that makes life on Earth possible, but have you considered how the Sun works?

The key to the Sun’s energy-supplying ability is a delicate balance between gravity and electromagnetism. Gravity curves space and pulls together all objects that have mass. The greater the mass, the greater the force of gravity. Right now gravity is pulling us toward the center of the Earth, but we are being held in place by the strength of the Earth’s crust and whatever floors or objects we have below us. The strength of the surfaces supporting us comes from electromagnetic forces between electrons and the protons in the nucleus of atoms. Those forces bond atoms of elements to each other forming compounds.

Since the Sun’s mass is more than a million times that of Earth, its gravity is more than a million times as great. The tremendous force in the core of the Sun overcomes the electromagnetic force and squeezes atoms of hydrogen tightly together igniting a thermonuclear reaction producing helium.

The creation of helium atoms releases high energy gamma-ray photons. If those gamma rays reached Earth, they would kill us. But the vast majority of them are transformed before they leave the surface of the Sun. On the way from the core to the surface they bounce off protons and electrons heating the hydrogen gas in the outer portion of the Sun. That heating increases the gas pressure enough to overcome the pull of gravity. Otherwise, the Sun would collapse on itself.

The bouncing of those gamma rays slows them so much that it takes hundreds of thousands of years for them to reach the Sun’s surface. If they could travel in a straight line, it would take only seconds, but they would emerge as deadly gamma rays that would reach the Earth in eight minutes, destroying all life. By the time those sterilizing gamma-ray photons reach the Sun’s surface, their energy has mainly been reduced to life-giving optical photons. There are still some dangerous rays that reach the Earth, but our atmosphere takes care of most of those.

That is a very simplified description of how the Sun works. Our Sun is a special star that provides the energy needed to sustain life on Earth without the high-energy rays that would destroy it. As you enjoy a beautiful sunset, you don’t have to know how the Sun works, but the Creator did. This finely-tuned system shows evidence of design by a Master Engineer, not a chance accident.

Fine-tuning of the Cosmos

Fine-tuning of the Cosmos in Introduction to Intelligent Design
Scientific articles mention the fine-tuning of the cosmos with increasing frequency. The basic concept is that the conditions of the universe are precisely set for human life.

The variables that affect the presence and sustainability of life are so precise that even slight variations would result in an inhospitable world. In his new book, Introduction to Intelligent Design, Dr. Timothy Gordon explains the concept very well by giving three examples of the fine-tuning of the cosmos.

“1. If the force of gravity were slightly larger, stars would be too hot and burn too rapidly making conditions for life inhospitable. If too small, no heavy elements would be produced.
2. The initial expansion of the Big Bang had to be fine-tuned to a precision of 1 in 10^55 to form planets, stars, solar systems, and galaxies.
3. There are 19 universal constants that must be perfectly tuned to make the universe habitable.
Assigning a probability to the fine-tuning of these constants would be larger than the number of elementary particles in the universe.” (page 43).

You will see many secular writers talking about the fine-tuning of the cosmos without explaining how this fine-tuning would come about without intelligence to do the tuning. This is another powerful argument for the existence of God as the creator.

We recommend Dr. Gordon’s book Introduction to Intelligent Design (ISBN: 9781095462645). It is formatted for Sunday-school and small group study and is available in paperback and Kindle editions.

Critical Initial Mass Function of the Sun

Yesterday we discussed the question of what real creation is about. Our point was that the study of real creation involves the study of how time, space, and matter/energy came into existence. Those sciences are in the embryonic stage, but they point to there being a purpose that involves wisdom and contributes to our understanding of the nature of God. One important finding of the study of creation is the critical initial mass function of the Sun.

As we study the Sun, we see that much is unique about our star. It is not just an average star of the billions formed from the “big bang” and classified in the Hertzsprung-Russell diagram. As we watch stars forming today and, as we look at the composition of the galaxy we live in, much stands out in our understanding of the Sun. Our mathematics indicate that there is what we call a critical initial mass function of the Sun, or IMF for short. IMF is the mass needed for star formation to take place. When stars begin to form from the material in the creation, they must have enough mass to allow gravity to fuse hydrogen into helium. If that mass isn’t there, what you have is a brown dwarf. If the mass is .08 of the solar mass, a red dwarf will form.

There are roughly 400 billion stars in the Milky Way, and 300 billion of them are red dwarfs – also called M dwarfs because of their spectral identification. There are roughly 15,000 places in our Milky Way galaxy where we see stars forming, so we can watch the way in which the IMF functions. When our Sun was formed, an IMF had to be carefully chosen so that it would produce a spectral G type star. Other star types such as O, B or F types would be too hot, too active and have too short of a lifespan. The most numerous stars in our galaxy – the red dwarfs mentioned earlier – have similar difficulties with their activity including stellar flares and coronal mass ejections. None of these types of stars can be seen as possible solar systems where life could exist.

The critical initial mass function of the Sun seems to be fine-tuned for life to exist. While we may have believed that by faith for many years, we now have scientific evidence to support that belief.
