If you ask paramecium, "Did you know that in this world, there is a life form that is tens of trillions of times more complex than you—human beings?" It is estimated that this single-celled organism, which has a lifespan of only a few hours, will laugh at you for dreaming.
If you tell a snail, "You can't climb to the other side of the world with all your life's work". It will tell you the truth of "one flower, one world" with actions.
If you wake up the bees: "Humans have invented spaceships that can fly into the solar system, and that's a distance you can never imagine." The bees are afraid that they will only buzz and continue to collect honey without hesitation.
If an ant is trampled to death by a passerby, the other ant who escapes the disaster will consider it a "natural disaster" rather than a "man-made disaster". Because all it saw was a black and swarthy giant that fell from the sky, but as everyone knows, it is just the sole of a human shoe.
Every living thing has its cognitive limitations. Humans are no exception.
In the concept of paramecium, humans are monsters.
At the foot of the snail, the other side of the earth is the horizon.
In the minds of bees, human spaceships are UFOs.
In the eyes of ants, the soles of shoes may be visitors from outside the world.
Is it possible that the universe is a cell of giants? - This is a question that is difficult to prove and falsify at the moment, and I am afraid that no one can give a convincing answer to everyone.
We just need to keep an open mind and believe that anything is possible.
Be skeptical of what is known.
Be curious about the unknown.
Be passionate about life.
Eternal reverence for life.
Even if: in the eyes of the sun, the earth is just a pinball.
In the eyes of the universe, human beings are just a speck of dust.
Even to the higher order of life, humans are as simple as the single-celled paramecium.
However, none of this can stop the current human beings from looking up to the stars and keeping their feet on the ground.
