Enjoy Our Beautiful Earth

ASTRONOMERS have seen that mankind’s home is just a tiny speck in the immeasurable reaches of a boundless universe. Nowhere else in the physical universe has life been found. Only on planet Earth have just the right conditions existed.

Moreover, we can enjoy life on this beautiful globe. How pleasant it is to feel warmed by the sun on a cold day! Who of us is not moved by a spectacular sunrise or sunset? Our sun, of course, does more than merely delight our senses. It is vital to our very existence.

For countless millions of years, the gravitational force of the sun has held the earth and other planets in stable orbits. And, as students learn in school, the whole solar system moves in orbit around the center of our Milky Way galaxy. But in our galaxy the sun is just one of more than 100 billion stars making this journey together.

The Milky Way galaxy is bound in a cluster of about 35 galaxies. Larger clusters contain thousands of galaxies. Our solar system likely would not be so stable if it were located in a much larger, dense cluster of galaxies. But, as it is, few regions of the universe “are as amenable to complex life as ours,” state Guillermo Gonzalez and Jay W. Richards in their book The Privileged Planet.

Is the existence of life on this planet the product of blind chance, the fortuitous result of some part of the “big bang”? Or is there a grander meaning to life on this beautiful planet Earth?

Many people have come to the conclusion that our earthly home was specifically designed to support life.a Centuries ago, a Hebrew poet called attention to the earth and the heavens. He wrote: “When I see your heavens, the works of your fingers, the moon and the stars that you have prepared, what is mortal man?” (Psalm 8:3, 4) This poet believed that there must be a Creator. Is that a reasonable conclusion in our scientific age?

Our Unique Solar System​—How It Got Here

MANY factors combine to make our part of the universe unique. Our solar system is located between two of the Milky Way’s spiral arms in a region that has relatively few stars. Nearly all the stars that we can see at night are so far from us that they remain mere points of light when viewed through the largest telescopes. Is that how it should be?

If our solar system were close to the center of the Milky Way, we would suffer the harmful effects of being among a dense concentration of stars. Earth’s orbit, for example, would likely be perturbed, and that would dramatically affect human life. As it is, the solar system appears to have just the right position in the galaxy to avoid this and other dangers, such as overheating when passing through gas clouds and being exposed to exploding stars and other sources of deadly radiation.

The sun is an ideal type of star for our needs. It is steady burning, long-lived, and neither too large nor too hot. The vast majority of stars in our galaxy are much smaller than our sun and provide neither the right kind of light nor the right amount of heat to sustain life on an earthlike planet. In addition, most stars are gravitationally bound to one or more other stars and revolve around one another. Our sun, by contrast, is independent. It is unlikely that our solar system would remain stable if we had to contend with the gravitational force of two or more suns.

Another factor that makes our solar system unique is the location of the giant outer planets that have almost circular orbits and pose no gravitational threat to the inner terrestrial planets.a Instead, the outer planets fulfill the protective function of absorbing and deflecting dangerous objects. “Asteroids and comets hit us but not excessively so, thanks to the presence of giant gas planets such as Jupiter beyond us,” explain scientists Peter D. Ward and Donald Brownlee in their book Rare Earth​—Why Complex Life Is Uncommon in the Universe. Other solar systems with giant planets have been discovered. But most of these giants have orbits that would endanger a smaller earthlike planet.

The Role of the Moon

From ancient times, our moon has filled mankind with wonder. It has inspired poets and musicians. For instance, an ancient Hebrew poet describes the moon as being “firmly established for time indefinite, and as a faithful witness in the skies.”​—Psalm 89:37.

One important way in which the moon affects life on earth is that its gravitational pull causes the ebb and flow of the tides. Tidal movements are thought to be fundamental to ocean currents, which, in turn, are vital for our weather patterns.

Another key purpose that our moon serves is that its gravitational force stabilizes earth’s axis with respect to earth’s plane of orbit around the sun. According to the scientific journal Nature, without the moon, the inclination of earth’s axis would wobble over long periods of time from “nearly 0 [degrees] to 85 [degrees].” Imagine if earth’s axis had no tilt! We would miss the delightful change of seasons and suffer from a shortage of rain. The earth’s tilt also prevents temperatures from becoming too extreme for us to survive. “We owe our present climate stability to an exceptional event: the presence of the Moon,” concludes astronomer Jacques Laskar. To fulfill its stabilizing role, our moon is large​—relatively larger than the moons of the giant planets.

Yet another function of the earth’s natural satellite, as noted by the writer of the ancient Bible book of Genesis, is that the moon serves as a light by night.​—Genesis 1:16.

Chance or Purpose?

How is one to explain the concurrence of multiple factors that make life on earth not only possible but also enjoyable? There appear to be only two alternatives. The first is that all these realities are the casual product of aimless chance. The second is that there is some intelligent purpose behind it.

Thousands of years ago, the Holy Scriptures stated that our universe was conceived and crafted by a Creator​—Almighty God. If that is true, it means that the conditions that exist in our solar system are the product, not of chance, but of deliberate design. The Creator left us with a report, so to speak, of the steps he took to make life on earth possible. It might surprise you to know that even though this report is some 3,500 years old, the events in universal history described in it basically correspond to what scientists believe must have taken place. This report is contained in the Bible book of Genesis. Consider what it says.

The Genesis Account of Creation

“In the beginning God created the heavens and the earth.” (Genesis 1:1) The Bible’s opening words refer to the creation of our solar system, including our planet, as well as that of the stars in the billions of galaxies that make up our universe. According to the Bible, at one time the earth’s surface was “formless and waste.” There were no continents and no productive land. But the next words highlight what scientists say is the most important requirement for a life-sustaining planet​—an abundance of water. God’s spirit was “moving to and fro over the surface of the waters.”​—Genesis 1:2.

For surface water to remain liquid, a planet must be the right distance from its sun. “Mars is too cold, Venus is too hot, Earth is just right,” explains planetary scientist Andrew Ingersoll. Similarly, for the growth of vegetation, there must be sufficient light. And significantly, the Bible account reports that during an early creative period, God caused the sun’s light to penetrate dark clouds of water vapor that enveloped the ocean like a “swaddling band” around a baby.​—Job 38:4, 9; Genesis 1:3-5.

In the next verses of Genesis, we read that the Creator produced what the Bible calls “an expanse.” (Genesis 1:6-8) This expanse is filled with gases making up earth’s atmosphere.

The Bible then explains that God changed the formless surface of the earth to make dry land. (Genesis 1:9, 10) He evidently caused earth’s crust to buckle and move. As a result, deep troughs may have been formed and continents pushed out of the ocean.​—Psalm 104:6-8.

At some unspecified time in earth’s past, God created microscopic algas in the oceans. Using energy from the sun, these self-reproducing one-celled organisms began to convert carbon dioxide into food while releasing oxygen into the atmosphere. This marvelous process was hastened during a third creative period by the creation of vegetation that eventually covered the land. Thus the amount of oxygen in the atmosphere increased, which would make it possible for man and animals to sustain their lives by breathing.​—Genesis 1:11, 12.

To make the land productive, the Creator caused a variety of microorganisms to live in the soil. (Jeremiah 51:15) These tiny creatures break down dead matter, recycling elements that plants use to grow. Special types of soil bacteria capture nitrogen from the air and make this vital element available to plants so that they can grow. Amazingly, an average handful of fertile soil may contain six billion microorganisms!

Genesis 1:14-19 describes the forming of the sun, moon, and stars in a fourth creative period. At first glance, this might seem to contradict the foregoing Scriptural explanation. Bear in mind, however, that Moses, the writer of Genesis, penned the creation account from the viewpoint of an earthly observer, had one been present. Apparently, the sun, moon, and stars became visible through earth’s atmosphere at that time.

The Genesis account assigns the appearance of sea creatures to a fifth creative period and that of terrestrial animals and of man to a sixth.​—Genesis 1:20-31.

The Earth Was Made to Be Enjoyed

Does it not seem to you that life on earth, which came about as described in the Genesis account, was made to be enjoyed? Did you ever wake up on a sunny day, breathe in the fresh air, and feel glad to be alive? Perhaps you took a walk in a garden and enjoyed the beauty and scent of the flowers. Or you might have walked in an orchard and picked some delicious fruit. Such delights would be impossible were it not for the following: (1) earth’s abundant water, (2) the correct amount of heat and light from the sun, (3) our atmosphere, with its right mix of gases, and (4) fertile land.

All these features​—absent on Mars, Venus, and our other planetary neighbors—​are not the product of blind chance. They were fine-tuned to make life on earth pleasurable. As the next article will illustrate, the Bible also says that the Creator designed our beautiful planet to last forever.

“If I as a geologist were called upon to explain briefly our modern ideas of the origin of the earth and the development of life on it to a simple, pastoral people, such as the tribes to whom the Book of Genesis was addressed, I could hardly do better than follow rather closely much of the language of the first chapter of Genesis.”​—Geologist Wallace Pratt.

JUST RIGHT FOR ASTRONOMY TOO

If the sun were located elsewhere in our galaxy, we would not have such a good view of the stars. “Our Solar System,” explains the book The Privileged Planet, “is located . . . far from dusty, light-polluted regions, permitting an excellent overall view of both nearby stars and the distant universe.”

The moon’s size and distance from the earth, moreover, are just right for the moon to cover the sun during a solar eclipse. These rare, awe-inspiring events permit astronomers to study the sun. Such studies have enabled them to unlock many secrets about how stars shine.

An Everlasting Gift From the Creator

DO YOU not find it amazing that the factors that scientists believe are essential for life on any planet either appear or are directly implied in the first chapter of the Bible? What are these?

For life to thrive, there must be a large quantity of water, as mentioned at Genesis 1:2. The temperature must be right for water on the planet to remain in liquid form. This requires that the planet be the right distance from its sun. The Genesis account repeatedly draws attention to the sun and its effect on the earth.

To be habitable by humans, a planet needs an atmosphere with a particular mix of gases. This vital aspect is mentioned at Genesis 1:6-8. The growth of vegetation, described at Genesis 1:11, 12, contributes to the rich supply of oxygen available. A planet on which a wide variety of animal life can thrive requires continents of dry, productive land, as described at Genesis 1:9-12. Finally, for moderate weather, a planet must be tilted to the proper angle and be held in place​—in the case of earth, a function fulfilled in part by the gravitational pull of our moon. This satellite’s existence and some of its benefits are highlighted at Genesis 1:14, 16.

How was the ancient writer Moses, without the help of modern science, able to draw attention to the above factors? Was Moses simply ahead of his time in appreciating their importance? The explanation is that he was inspired by the Creator of the heavens and the earth. That is noteworthy in view of the scientific soundness of the Genesis account.

The Bible affirms that there is a purpose behind the wonders that we observe in the universe around us. “As regards the heavens, to Jehovah the heavens belong,” states Psalm 115:16, “but the earth he has given to the sons of men.” Another psalm states: “He has founded the earth upon its established places; it will not be made to totter to time indefinite, or forever.” (Psalm 104:5) If the universe and our beautiful planet are designed and produced by a Creator, surely it is not too much to believe that he also has the ability to maintain these. This means that you can confidently look forward to the fulfillment of the wonderful promise: “The righteous themselves will possess the earth, and they will reside forever upon it.” (Psalm 37:29) To be sure, God “did not create [the earth] simply for nothing” but “formed it even to be inhabited” forever by appreciative humans who acknowledge his doings.​—Isaiah 45:18.

According to the Scriptures, Jesus came to earth to teach us about God and His purpose to grant everlasting life to obedient mankind. (John 3:16) We are assured that soon God will “bring to ruin those ruining the earth,” whereas peace-loving humans from all nations who accept his provision for salvation will survive. (Revelation 7:9, 14; 11:18) How wonderful life will be as humans keep on discovering and enjoying the marvels of God’s creation forever!​—Ecclesiastes 3:11; Romans 8:21.
