According to the Big Bang theory, the universe was in a state of infinitely high density and temperature a finite time in the past, a state known as a singularity. Then, in a very short time, this singularity was extremely inflated, forming the universe, including the elementary particles in it. These elementary particles make up my body, my life. So my body used to be particles on every planet. Then the universe continued to expand and evolved into the sun and the earth. Earth provided the environment, and self-replicating RNA molecules emerged, and the resources needed for these life to reproduce were limited, so competition soon began. Since natural selection favored molecules that were more efficient at replicating, DNA gradually became the predominant replicator. They then begin to develop within membranes, which have a more stable physical and chemical environment, forming primitive cells. Then came prokaryotes, which evolved glycolysis, which produces the adenosine triphosphate (ATP) molecule used by all living things today to temporarily store energy. Finally, a common ancestor appeared, and bacteria and archaea split. Life evolves all the way. . . Multicellular organisms, polyporous animals, platyhelminths and other multicellular animals, arthropods, chordates. . . The last common ancestor of humans and mice appeared 75 million years ago. Then I went through various social changes, wars and various natural disasters, including earthquakes, floods, etc. and man-made disasters. Whether it was luck or physical advantages, my ancestors survived, and recently experienced the alternate rule of various ethnic groups, a The Ming clan planned to wipe out another Ming clan, and then to the Sino-Japanese War, the Civil War, and the Cultural Revolution, my ancestors went all the way down. Finally, at the end of the hundreds of billions of sperm, the first one swam to the egg, and after entering it, I emerged. Along the way, "I", walked for a long time, very far. In the end, if you are lucky enough, through DNA, "I" will continue to walk, and eventually to the universe. The stars, my home. Maybe, I know where "I" came from and where I'm going. But I don't know where I will go in this short life, who I will meet, who I will like or dislike, who I will like or dislike, what I will experience, happy or painful, happy or sad, whatever, hope it's fun . Is life magical? of course, they say every atom in our bodies was once part of a star. Maybe I'm not leaving. Maybe I'm going home. -Vincent,
