How did our universe come into being?
According to the existing observational data and theories, the observable universe appeared about 13.8 billion years ago, with an error margin of ±20 million years. There is no solution to the discussion of "whole universe" or "multiverse".

We have only one earth
I love the moon, her purity, her mystery, and her eternity. On the day of the Mid-Autumn Festival, I sat in my crib in the courtyard after dinner and quietly waited for the moon to come. After a while, the moon sister quietly revealed her round smiling face, looking down on the vast earth. Everything in the countryside seemed to be covered with a thin layer of sand by the moon, like a realistic jade sculpture, solemn and beautiful. My sister came over and took us by the hand and told us the story of "Change running to the moon".
