That is our home with everyone you love and everyone you know. Everyone you've ever heard of, everyone who's ever existed, has spent his life there. Our joys and pains, thousands of beliefs, ideologies, economic theories, all hunters and predators, all heroes and cowards, every creator and destroyer of civilization, every king and peasant, Every young couple in love, every mother and father, every child with a bright future, every inventor and explorer, every teacher with good morals, every corrupt politician, every superstar, Every outstanding great man, all saints and sinners in human history, lived there, like a speck of dust, floating in the radiance. In the vast universe, the earth is a small stage. Think of those kings and soldiers who were suffocating mountains and rivers. In order to gain victory and glory, in order to become the master of a certain area, they would not hesitate to take other people's lives cruelly. Compared with the vast universe, they once had too little and too little. Thinking about the long war years, why does every ethnic group on earth face the other ethnic group with ice blades? They often misunderstand each other, they want to kill each other, their hatred is so strong.
We postulate, we think we are invaluable, we fantasize about our privileged place in the universe.
But now, do you still think so?
Our planet is just a drop in the ocean, and we are so insignificant in this ever-expanding universe.
In this vast universe, no one can save us except ourselves, and the earth is the only known place that can breed life. At least for a while, there was nowhere for humans to settle.
Whether you like it or not, at this moment, we can only live on Earth, where our ancestors have lived for generations.
It is said that studying astronomy can make one humble and help shape one's personality.
Perhaps nothing makes humans more aware of their stupidity and conceit than this picture.
For me, we have to take our responsibilities, be kinder to those around us, and protect and cherish our earth with our hearts.
This is our current, only home.
