Whenever comparing items, we need references as a perspective. A mouse is small to us, but we are small compared to a blue whale, and the mouse is large compared to one of its cells. Yet, that same whale is small compared to Mt. Everest, which is a meager spot on or planet – but Earth is so small compared to Jupiter.
The pattern can continue to the Sun, our solar system, to the Milky Way, all the way to the universe. Oh, the wonders that creation provides.
Wonder continue as we go in the opposite direction by examining our cells, to cell parts, to the molecule, its atoms, the atomic parts, and even to the smaller quarks.
Each microliter of human blood has approximately 5 million red blood cells (RBC). Considering that 1 liter contains 1 million microliters, and humans have 5 liters of blood, the total number of RBCs in each of us is quite large. Toss in the fact that each RBC contains 250 million molecules of hemoglobin that is responsible for transporting oxygen and carbon dioxide through over 60,000 miles of blood vessels – and this is in each of us.
As social beings, each of us know many people – well, we think we do – but compared to the world population, are interactions are limited to a mere few. Encounters of the cyberkind expand our world, but it is still small.
Each of us have countless daily interactions – some positive, others negative, and most have little effect. Sometimes we know when we affect the life of another, but much of the time, we stand in a clueless abyss. After all, we do not know when the effect of that encounter is transferred to others – perhaps even years later.
Toss in the element of time – all the people who passed before me, and all those who lie ahead of my time. People born, people die. A few become notables, most are commoners. Some are giants to societies. Some are giants in their towns, while others are giants in a family – but many are simply everyday people playing a niche in life. Yes, we all have history and in time, forgotten. Of all these people, only a selected few have recognized names of distinction – and only a few of them will make history books.
I am only 1 of over 7 billion people on our planet at this time, and only 1 of about 108 billion humans born to through the ages.
In some way, these thoughts make me feel worthless. On the other hand, science – and yes, my Christian views – allow me to appreciate being a tiny speck living on a particle of dust in the universe that is vast and intricate – thus I impressed and overwhelmed.
