Not Every Alcohol Is the Same: Ethanol vs. Benzyl Alcohol

When most people hear the word “alcohol,” they immediately think of the substance present in liquors that affects the brain and behavior. But in chemistry, “alcohol” is a much broader category of organic compounds, all sharing a common feature: an –OH (hydroxyl) group attached to a carbon atom. Different alcohols can look similar on paper but behave very differently in the human body.

One alcohol that often raises questions is benzyl alcohol, which is widely used in consumer products. Many toothpaste brands, cosmetic items, and even certain medicines contain benzyl alcohol as a preservative or solvent. Because it carries the name “alcohol,” some people mistakenly assume it might act like the alcohol in liquors. In reality, the two are entirely different in both structure and effect.

The Structure of Alcohols

All alcohols share the hydroxyl group (–OH), but their surrounding structures matter greatly.

  • Ethanol (C₂H₅OH): A small, simple molecule with just two carbons. This is the alcohol found in liquors, and it directly affects the brain’s communication system.
  • Benzyl Alcohol (C₆H₅CH₂OH): A larger molecule with a benzene ring attached to the –CH₂OH group. This makes it chemically heavier, less volatile, and unable to produce the same effects in the brain.

Why Ethanol Affects the Brain

Ethanol is unusual among alcohols because:

  • It is small and water-soluble, allowing it to cross the blood–brain barrier quickly.
  • Once in the brain, it interacts with neurotransmitter systems (such as GABA and glutamate), slowing down neural activity and creating the well-known changes in mood, coordination, and alertness.

This is why ethanol has a direct impact on human behavior.

Why Benzyl Alcohol Does Not

Benzyl alcohol does not act like ethanol:

  • Its large benzene ring makes it behave differently in the body.
  • It is mostly used as a topical agent, preservative, or mild local anesthetic, not as a substance that alters the brain.
  • When absorbed in small amounts (for example, from toothpaste or cosmetics), the body metabolizes it to benzoic acid, which is harmless in normal quantities and naturally found in some fruits.

Thus, while it is chemically an alcohol, benzyl alcohol has no intoxicating effect.

Other Alcohols: A Quick Comparison

Chemistry knows many alcohols, but only ethanol has the specific combination of size and solubility that allows it to strongly affect the brain. A few others deserve mention:

  • Methanol (CH₃OH): Extremely toxic; even small amounts can damage the optic nerve and cause blindness or death.
  • Isopropanol (C₃H₇OH): Found in disinfectants (“rubbing alcohol”). Can cause dizziness at high doses but is far more poisonous than ethanol.
  • Higher alcohols (propanol, butanol, amyl alcohols): Sometimes produced in tiny amounts during fermentation. They can contribute to unpleasant side effects if ingested but are never safe to consume directly.
  • Aromatic alcohols (like benzyl and phenethyl alcohol): Common in fragrances, cosmetics, and natural oils. Useful and safe in small quantities, but not brain-active.

This comparison highlights an important lesson: the word “alcohol” does not always mean the same effect or risk.

Everyday Use of Benzyl Alcohol

Because of its properties, benzyl alcohol is widely used in daily life:

  • As a preservative in toothpaste and skincare products.
  • As a solvent in medications and cosmetics.
  • As a mild anesthetic in certain medical preparations.

It is safe for these purposes and does not cause the changes in mood, thinking, or behavior that ethanol does.

Diagram: Comparing the Two

This simple diagram shows how the presence of the benzene ring makes benzyl alcohol chemically distinct from ethanol.

Conclusion

The key point is clear: not every alcohol is the same. Ethanol, the type of alcohol in liquors, is unique in its ability to cross into the brain and affect neural activity. Benzyl alcohol, by contrast, is used safely in toothpaste, cosmetics, and medicines without producing those effects.

So when you see “benzyl alcohol” on the ingredient list of a toothpaste or cream, there is no reason to confuse it with the alcohol found in liquors. They may share a name, but their structures and impacts on the body are completely different.

Chocolate Powder vs Cocoa Powder: Understanding the Difference

When people visit a supermarket, they often see two similar-looking tins on the shelf — one labeled cocoa powder and another labeled chocolate powder. At first glance, they may seem like the same thing, but they are not. The difference between the two lies in the way they are made, what they contain, and how they are used in food and drinks. To understand this clearly, we need to look into the journey of the cocoa bean, the separation of cocoa butter and cocoa solids, and the reason why companies sell both products separately.

From Cocoa Bean to Cocoa Mass

Cocoa products begin with the cocoa bean, the seed of the Theobroma cacao tree. The beans are fermented, dried, roasted, and cracked to remove the shells, leaving behind the cocoa nibs.

These nibs are ground into a thick, brown paste known as cocoa mass (sometimes called cocoa liquor, though it contains no alcohol). Cocoa mass is not a dry powder. It is a suspension of:

  • Cocoa butter (the fat, which is liquid at high temperatures and solid at room temperature).
  • Cocoa solids (tiny dark particles that give cocoa its flavor, color, and nutrients).

So cocoa mass is a combination of both fat and solids.

The Hydraulic Press: Separating Fat and Solids

The key step in making cocoa powder is separating these two components. This is done using a hydraulic press, a machine that applies very high pressure — up to 600 bar.

Here is how it works:

  1. Cocoa mass is placed into a chamber lined with fine mesh filters.
  2. Under massive pressure, cocoa butter (the liquid fat) is squeezed out.
  3. Cocoa solids are too large to pass through the mesh, so they remain behind, compressed into a hard block called the press cake.
  4. The press cake is later ground into fine cocoa powder.

This process works because cocoa butter is a true liquid (when heated to around 90–100°C) and can seep through tiny filter openings, while the cocoa solids are larger, micron-sized particles that cannot escape. In other words, the press acts like a powerful filter: liquid fat flows out, but the solids stay compacted.

Cocoa Powder: The Solids Without the Fat

Once separated, the press cake is milled into cocoa powder. This powder contains mainly:

  • Cocoa solids (flavor, color, antioxidants, fiber).
  • Very little cocoa butter (usually 10–20%).

Because it has a low fat content, cocoa powder has:

  • A stronger, more bitter chocolate taste.
  • A dry, dusty texture.
  • Excellent solubility in hot liquids.

That is why cocoa powder is widely used in:

  • Baking (brownies, cakes, cookies).
  • Hot drinks made with milk or water.
  • Flavoring ice cream and desserts.

Cocoa Butter: The Valuable Fat

The fat that is squeezed out — cocoa butter — does not go to waste. It is one of the most valuable products of the cocoa bean. Cocoa butter is:

  • Pale yellow, creamy, and melts just below body temperature.
  • Used to make smooth, melt-in-the-mouth chocolate bars.
  • Essential for giving chocolate its shine, snap, and texture.
  • Also widely used in cosmetics, lip balms, and pharmaceuticals for its stability and skin-friendly properties.

So the removal of cocoa butter is not just about making cocoa powder; it is also about obtaining a separate fat with important uses.

Chocolate Powder: Cocoa Plus Sugar

Now let us return to the supermarket shelves. If cocoa powder is simply the ground solids from the cocoa bean, then what is chocolate powder?

Chocolate powder is usually a ready-to-use mix. It typically contains:

  • Cocoa powder.
  • Sugar.
  • Sometimes milk powder.

The purpose of chocolate powder is convenience. It is designed to be stirred straight into hot or cold milk to make a sweet chocolate drink. It is smoother, lighter in taste, and less bitter than pure cocoa powder.

In other words:

  • Cocoa powder = pure, unsweetened, strong flavor.
  • Chocolate powder = blended, sweetened, easy to drink.

Popular Examples (Including Cadbury)

Several brands around the world sell both cocoa powder and chocolate powder. For instance:

  • Cadbury Cocoa: This is pure cocoa powder, unsweetened, meant for baking or making rich cocoa drinks (you usually need to add sugar).
  • Cadbury Drinking Chocolate: This is chocolate powder, containing cocoa plus sugar, made for stirring into milk directly.

Outside Cadbury, other brands like Nestlé, Hershey’s, and Ghirardelli follow the same principle: they sell unsweetened cocoa powder for cooking, and sweetened chocolate mixes for instant beverages.

Nutritional and Taste Differences

The difference in composition also means differences in nutrition and taste:

  • Cocoa powder:
    • Low in fat (about 10–20%).
    • Rich in antioxidants (flavanols).
    • Strong, slightly bitter taste.
    • High in dietary fiber.
  • Chocolate powder:
    • Higher in sugar (often 70–80% of the mix).
    • Lower in antioxidants (because cocoa is diluted).
    • Sweet, mild taste.
    • Provides quick energy but less health benefit.

So if you want the intense chocolate flavor for recipes or health benefits, cocoa powder is the choice. If you want a quick, sweet drink, chocolate powder is more suitable.

A Simple Analogy

To make it easier, imagine you have ground peanuts:

  • If you squeeze out the oil, you get peanut oil (like cocoa butter) and a dry powder (like cocoa powder).
  • If you mix that powder back with sugar and milk powder, you get a sweet peanut drink mix (like chocolate powder).

The same logic applies to cocoa.

Conclusion

The difference between chocolate powder and cocoa powder lies in the separation of fat and solids within the cocoa bean. Cocoa powder is made by pressing cocoa mass to remove cocoa butter, leaving behind concentrated cocoa solids. Chocolate powder, on the other hand, is a mixture of cocoa powder with sugar (and sometimes milk), intended as a convenient sweetened drink mix.

Cocoa butter, the fat removed in the process, is used in making chocolate bars, confectionery, and cosmetics. Cocoa powder, rich in flavor and nutrients, is favored in baking and recipes. Both products, though born from the same bean, serve very different purposes.

So the next time you see two tins on the supermarket shelf — one labeled cocoa and one labeled chocolate — you’ll know that one is the pure, intense ingredient for baking and cooking, while the other is a sweetened shortcut for an instant chocolate treat.

The Vital Layers Between Air and Space: Stratosphere, Mesosphere, and Thermosphere

Above the breathable air we call atmosphere lies a realm of hidden guardianship, protecting life on Earth in ways we often take for granted. Between the layer of air (hawa) that surrounds our planet and the vast openness of space exist three significant layers: the stratosphere, the mesosphere, and the thermosphere. Each performs remarkable functions, silently sustaining life and maintaining balance on Earth.

Interestingly, the Ikhwan al-Safa (Brethren of Purity), in their encyclopedic writings, refer to a cosmic layer called Qurrat un Naar (also called Qurrat uz Zamhareer) situated above the air. While the exact nature of this term remains profound and symbolic, one may reflect that this description could be referring—at least in part—to one or more of these atmospheric layers that act as boundaries and shields between Earth’s air and the expanses of the heavens. Allah and His Awliya know best.

Let us look closely at each of these three layers, their mechanisms, and their indispensable role for life on Earth.

1. The Stratosphere (12–50 km): Home of the Ozone Shield

Just above the troposphere (where weather and clouds exist) lies the stratosphere, a calm and stable zone. Its most celebrated feature is the ozone layer, concentrated roughly 15–35 km above Earth.

  • Mechanism:
    The ozone layer absorbs the Sun’s harmful ultraviolet (UV) radiation, particularly the dangerous UV-B rays. Without this protection, DNA in living organisms would be severely damaged, leading to genetic mutations, skin cancers, cataracts, and collapse of ecosystems. The ozone molecules absorb high-energy photons and convert them into harmless heat, moderating solar radiation before it reaches the surface.
  • Importance:
    1. Life Shield: Protects all terrestrial and aquatic life from lethal radiation.
    2. Climate Role: By absorbing UV rays, the ozone layer warms the stratosphere, creating a temperature gradient that stabilizes air currents and reduces violent mixing between troposphere and higher layers.
    3. Aviation Corridor: Because of its stable air and low turbulence, the lower stratosphere is often used for high-altitude flight paths.

This invisible blanket is indispensable—without it, Earth would be scorched, barren, and unable to support the delicate balance of life.

2. The Mesosphere (50–85 km): Earth’s Meteor Shield

Rising further, we enter the mesosphere, a colder, thinner region of the atmosphere. While it may seem empty, it plays a vital defensive role.

  • Mechanism:
    Every day, countless small meteoroids, fragments of rock and dust, enter Earth’s path. Traveling at tens of kilometers per second, they would be devastating if they struck the surface in large numbers. Instead, as they encounter the dense friction of the mesosphere, most burn up spectacularly, producing the streaks of light we call “shooting stars.”
  • Importance:
    1. Protective Barrier: Prevents continuous bombardment by meteors, sparing Earth from destruction.
    2. Circulation System: Supports the mixing of atmospheric gases and plays a role in transporting energy and chemicals between lower and higher layers.
    3. Noctilucent Clouds: Hosts mysterious, shimmering clouds that glow after sunset, reflecting sunlight from beyond the horizon. These clouds are sensitive indicators of climate change and upper-atmospheric conditions.

The mesosphere silently performs its duty as Earth’s natural shield against celestial debris, absorbing impacts that could otherwise erase civilizations.

3. The Thermosphere (85–600 km): The Radiant Veil of Auroras

Above the mesosphere stretches the thermosphere, a vast and dynamic region extending hundreds of kilometers into space. Though the air here is exceedingly thin, it is packed with energetic interactions.

  • Mechanism:
    Solar radiation, particularly extreme ultraviolet and X-rays, bombards this layer. Atoms and molecules absorb this energy, becoming ionized. This ionized region, often called the ionosphere, reflects and modifies radio waves, enabling long-distance communication. Another marvel occurs when charged particles from the solar wind funnel along Earth’s magnetic field lines and collide with atmospheric atoms. The result is the breathtaking aurora borealis (northern lights) and aurora australis (southern lights). These curtains of green, red, and violet light dance across polar skies, a testimony to the dynamic interaction between the Earth and the Sun.
  • Importance:
    1. Communication and Navigation: Enables radio transmission, GPS, and satellite operations by reflecting or bending signals.
    2. Radiation Shield: Absorbs extreme radiation that would otherwise sterilize the planet.
    3. Human Endeavors: The thermosphere is where spacecraft and the International Space Station orbit, allowing humanity to explore and monitor Earth from above.

The thermosphere stands as Earth’s luminous crown, shimmering with protective energy.

A Spiritual Reflection: Qurrat un Naar and the Hidden Boundaries

The Ikhwanus Safa described Qurrat un Naar (Qurrat uz Zamhareer) as a profound cosmic sphere above the air. While their descriptions carry symbolic and metaphysical depth, one cannot help but reflect that these protective layers—the stratosphere with its shielding ozone, the mesosphere with its fiery defense against meteors, and the thermosphere glowing with auroras—may resonate with such a description.

Each of these layers acts as a veil between the breathable atmosphere and the openness of space, guarding Earth with invisible yet mighty powers. Whether Qurrat un Naar encompasses one or more of these layers remains a matter of divine knowledge—Allah and His Wali know best. What is clear is that these layers are not mere scientific curiosities, but essential guardians without which life could never flourish on Earth.

Conclusion

Between the air we breathe and the vast expanse of space, three atmospheric layers silently perform their ordained roles:

  • The stratosphere shields life with ozone.
  • The mesosphere burns meteors before they strike.
  • The thermosphere radiates light and guards against deadly solar energy.

They are unseen protectors, part of the intricate order by which Earth has been designed. And perhaps, in their silent service, lies the reflection of that mysterious cosmic layer described in ancient wisdom as Qurrat un Naar—a reminder that both the visible and invisible realms work together in harmony, preserving the gift of life.

The Inner Fire of Plants and Fruits: The Chemistry of Ripening

When fire cooks food, raw ingredients are softened, flavored, and made digestible. Similarly, fruits ripen by an invisible “inner fire” that transforms them from hard, sour, green forms into sweet, soft, and fragrant treasures. This fire is not made of flames but of living chemical reactions—a constant energy flow within every plant and fruit.

1. Fire in Plants: Life’s Constant Oxidation

Every green plant, tree, and fruit lives by two great forces:

  • Photosynthesis: the capturing of sunlight, storing its energy in the form of carbohydrates (starch, sugars).
  • Respiration: the controlled burning of those carbohydrates with oxygen, releasing energy.

In respiration, glucose (C₆H₁₂O₆) + oxygen (O₂) → carbon dioxide (CO₂) + water (H₂O) + energy (ATP + heat).

This is the fire of life, burning silently inside each cell. Unlike an external flame, it is a slow, regulated combustion that never stops as long as the plant lives.

2. Fruit Ripening: When the Fire Peaks

Fruits are not dead storage organs; they are alive, breathing, and full of potential energy. When ripening begins, this cellular fire intensifies, especially in climacteric fruits (mango, banana, apple, tomato).

  • Ethylene acts as the spark—it signals the fruit to start ripening.
  • Stored compounds (starch, organic acids, chlorophyll, hard pectin) act as the fuel.
  • Respiration—oxidation of sugars and acids—is the fire that releases energy to break down, build up, and rearrange molecules.

This is why ripening is often called a “metabolic blaze.”

3. The Chemical Transformations: Cooking from Within

a) Breakdown of Starch into Sugars

  • Enzyme amylase converts starch into glucose, fructose, and sucrose.
  • This is like roasting a grain until it turns sweet.
  • Result: fruits taste sweeter.

b) Oxidation of Organic Acids

  • Citric acid, malic acid, tartaric acid serve as “fuel” in respiration.
  • They are oxidized in the mitochondria’s Krebs cycle to CO₂ and H₂O.
  • Result: fruit loses its sourness, flavor balances.

c) Degradation of Chlorophyll, Emergence of Colors

  • Chlorophyll, once dominant, is oxidized and dismantled.
  • Hidden pigments—carotenoids (yellow/orange) and anthocyanins (red/purple)—now glow.
  • Result: fruits signal readiness with bright colors.

d) Softening of Cell Walls

  • Enzymes like polygalacturonase and cellulase break down pectin and cellulose.
  • The energy from respiration powers enzyme production.
  • Result: fruits soften, become juicy and edible.

e) Aroma and Volatile Compounds

  • Through oxidation–reduction reactions, enzymes convert fatty acids and amino acids into esters, aldehydes, and alcohols.
  • These volatile molecules are the perfumes of ripeness.
  • Result: fruits advertise themselves with fragrance.

4. Fire Beyond the Fruit: In the Whole Tree

The same oxidative “fire” that ripens fruits also burns in the leaves, trunk, and roots of the tree.

  • In leaves, respiration balances photosynthesis.
  • In roots, respiration releases energy to absorb water and minerals.
  • In fruits, the fire intensifies at the climacteric stage, making changes visible.

Thus, the ripening of fruits is not an isolated miracle but a climactic expression of the same living fire that sustains the entire tree.

5. The Duality of Fire: Flame vs Breath

  • In flames, carbon is oxidized violently, releasing light and heat.
  • In fruits, carbon compounds are oxidized gently, releasing controlled energy to rearrange molecules.

Both are fire—one external, one internal. One consumes wood, the other transforms fruit.

6. Conclusion: Ripening as Nature’s Alchemy

The ripening of fruit is like a slow cooking, powered by an inner fire:

  • Spark: Ethylene
  • Fuel: Starch, acids, chlorophyll, pectin
  • Fire: Oxidative respiration, chemical transformations

This fire is not only in fruits but in the whole tree—an eternal combustion of life. It is what turns sunlight into sweetness, hardness into softness, sourness into balance, greenness into color, silence into fragrance.

Article 1- Beyond Evolution: Rethinking the Story of Human Existence

Article 1 — The Origin of Life: Why Chemistry Alone Looks Unlikely

In this series, we are exploring why the theory of evolution does not seem to provide a solid explanation for human existence. Each article will focus on one key example where evolution feels scientifically weak or logically impossible. Instead of blindly accepting the idea that “everything just evolved,” we are carefully analyzing the first steps of life, complexity, and human uniqueness.

Today’s article looks at the very beginning of life — the point before evolution could even start.

A Simple Analogy

Imagine walking along a beach and finding a smartphone lying in the sand. You could describe how later models of the phone became faster, slimmer, and more advanced, but that would not explain how the very first phone assembled itself out of sand and seawater. The problem is not small — it is foundational. Unless you can explain how the first phone came to be, the rest of the story is incomplete.

This is the same challenge faced when we ask: how did life itself begin?

Life’s First Mystery

Evolution is often presented as a complete explanation for how humans and other creatures exist. But what is often left unspoken is that evolution begins after life has already started. The real mystery lies in the very first step: how did lifeless matter become the first living cell?

A living cell is not just a bag of chemicals. It is a miniature factory. Inside, there are recipes (DNA), machines to read those recipes, and engines to power the work. All three are required at the same time. If you only have recipes but no machine to read them, nothing happens. If you have machines but no recipes, they build nothing. And if you have recipes and machines but no source of fuel or a protective container, the system collapses immediately.

That is the puzzle: how could such a tightly interdependent system appear from plain chemistry, without guidance?

Scientific Attempts

Scientists have suggested different ideas to bridge this gap. Some say the early oceans were like a “primordial soup,” rich in chemicals that somehow joined together into life. But chance cannot realistically assemble the complexity of a living cell. Others suggest an “RNA World,” where simple molecules began copying themselves, but these molecules are fragile and fall apart quickly. Still others propose that life arrived from outer space, through comets or meteors. But this only shifts the question: where did life begin in the first place?

Each attempt highlights the same truth: the first step of life remains unexplained.

Why This Matters

If the origin of life cannot be explained, evolution has no starting point. It can only describe changes in life after it exists; it cannot tell us how life began. That missing first step is not a minor detail — it is the foundation of the entire story. Without it, the chain of evolution hangs in midair, unsupported.

Looking Ahead

In the next article of this series, we will move beyond the question of life’s origin and look at the genetic code in DNA. Like a carefully written program, DNA contains instructions that guide every living process. But where did such a precise language come from, if there was no mind behind it?

Stay with us as we continue to examine the weaknesses of the evolutionary model and search for a deeper explanation of human existence.

Measuring the Universe

A Journey Through Falak, Stars, and Beyond

When we look at the night sky, we see shining points of light—planets, stars, and galaxies. These are not abstract ideas, but real creations, arranged in perfect order. The Qur’an describes the seven skies, each layered above the other: the orbits of the Moon, Mercury (ʿUṭārid), Venus (Zuhra), the Sun (Shams), Mars (Mirrikh), Jupiter (Mushtarī), and Saturn (Zuhal). Beyond them lies the Falak al-Burūj, the sphere of stars. Still farther is the Falak al-Muḥīṭ, the all-encompassing sky.

To sense the immensity of these spheres, we can shrink the universe onto paper and hand-held scales. Through three stages, the vastness of creation comes into perspective.

Stage One: Earth as a 1 mm Dot

Draw a tiny 1 mm dot on paper. That dot represents Earth.

  • The Moon’s orbit lies only a few cm away.
  • The Sun would be about 15 cm from the dot.
  • Jupiter more than 1 m out.
  • Saturn, the seventh sky, nearly 3 m away.

Even on a room-sized sheet, the planetary system barely fits. And yet this is only the opening act of the heavens.

Stage Two: Shrinking the Seven Skies

Now shrink the entire planetary system—Earth to Saturn—into a single 1 mm circle. That speck contains all the planets and their orbits.

Beyond it lies the Falak al-Burūj, the starry sphere. To mark its edge, we use Earendel (the farthest star detected so far). Its light has traveled about 12.9 billion years to reach us.

At this scale:

  • Saturn’s orbit = 1 mm
  • Distance to Earendel ≈ 85 million km on paper

To grasp this size, compare with Earth’s diameter (12,742 km). The paper needed equals 6,700 Earths laid side by side. Imagine covering such a sheet just to draw the stars!

This shows how tiny the planetary skies are compared to the starry heavens.

Stage Three: The Egg and the Infinite Desert

Now imagine shrinking the entire Falak al-Burūj—all stars and galaxies up to Earendel—into the size of a chicken egg, about 5 cm wide. Inside that egg sits the whole visible universe.

Beyond it stretches the Falak al-Muḥīṭ, the all-encompassing sphere. Modern astronomy estimates the radius of the observable universe at about 46.5 billion light-years. In our scale, that would be about 36 cm—slightly larger than a small book.

But the truth is greater. Falak al-Muḥīṭ is not limited to what we can see. The visible universe is only the starting point, like a tiny egg placed in a vast desert. Beyond it lies an endless expanse that no telescope can capture, no imagination can measure.

Reflections

These stages are not just numbers, but lessons:

  • Perspective – Earth is a dot, the planets a speck, the stars thousands of Earths wide, and the visible universe an egg in an infinite desert.
  • Reality – The Qur’an’s skies are real, not symbolic. Each layer opens into realms greater than the last.
  • Infinity – Even our most powerful vision sees only a speck in the limitless ocean of Falak al-Muḥīṭ.

Conclusion

All of this vast machinery—the skies, planets, stars, and galaxies—was created not in vain, but with purpose. Humanity is the pinnacle of this design. The universe exists as a stage for human beings, who are destined to recognize, serve, and reflect the wisdom of Allah.

So when you look at the heavens, whether a single star or the thought of infinite space, remember: it all exists so that humans may live, know, and fulfill their purpose.
