First of all, from 0: 00, the solar system just formed, and the remaining nebula remnants gradually merged together to form the original earth. 0: 1 1, a planet named Teia collided with the earth, and the huge impact produced countless fragments. Under the action of gravity, these fragments began to gather together, forming the early moon. At 0: 47, the post-solar bombing period ended, the earth's surface began to cool slowly, and the solid crust gradually formed.

At 1: 50 in the morning, the atmospheric temperature gradually stabilized, and the earth began to experience heavy rain that lasted for millions of years. All the water sources came together to form the early primitive ocean. At 3 o'clock in the morning, on the edge of the deepest crater on the seabed, a group of organic molecules quietly gathered together and magically evolved the oldest life on earth. At 5 am, the ancestor of all cells, or the last ancestor of all species on earth before differentiation, Luca was born. At 10: 20 in the morning, cells had the ability similar to photosynthesis, and the oxygen content in the atmosphere began to increase rapidly, and some oxygen was converted into ozone, gradually forming today's ozone layer.

At 5: 00 p.m. 15 p.m., the cells finally evolved into mitochondria that produce energy, and the division of labor and cooperation between cells. More and more mature and complex multicellular organisms began to appear. At 8: 20 p.m., life on earth is no longer confined to the ocean, and some marine plants begin to migrate to land, and quickly spread to all corners of the world.

At 9 o'clock in the evening 10, the Cambrian ushered in a big explosion of life, and many complex life forms appeared one after another. A thriving scene began to appear on the earth. At 9: 27 pm, Gondwana mainland entered the Antarctic region. The great glacier changed the direction of ocean currents in an unprecedented way, and the temperature of the whole earth began to drop sharply, eventually leading to the disappearance of more than 85% species, which was called the first mass extinction in history. At 9: 42 pm, with the development and prosperity of plants on land and providing a large number of food sources, marine life began to gradually migrate to land.

From 10 in the afternoon to 1 1 in the afternoon, three more mass extinctions occurred on the earth in just one hour. It caused a devastating blow to the life at that time, but the dinosaur was lucky to survive. At night. 1 1: 39, a meteorite with a diameter of 10 km hit the earth, causing a devastating disaster. With the wailing of many creatures, the fifth extinction officially began. At night 1 1: 40, a small animal covered in hair and shaped like a mouse was lucky to survive in the ruins.

He is now the ancestor of all primates. At night, 1 1: 59: 22, the first anthropoid animal finally appeared on the earth. But at this time, human beings are still extremely primitive and do not have any ability to distinguish themselves from other animals. At night 1 1: 59: 45, Homo erectus finally learned to use flame. With this great advantage, they began to stand out among many animals and gradually went to all parts of the world.

At night 1 1: 59: 58, the early homo sapiens, the thinking ability of modern humans recognized by the scientific community, appeared on the African continent. At the last 0. 1 sec, the first civilization in human history was born in the two river basins. At the last 0.0 1 sec, human beings formally entered the modern society and put forward the theory of evolution and evolution. Yes, we are the first species to break through the biosphere limit in less than 10 million years since the birth of the earth 4.6 billion years ago.

But we did do the most harm to the earth. According to the research of scientists, we are currently in the sixth extinction period. Due to the influence of human activities, the extinction rate of species today is more than 100 times of the average extinction rate in the evolution of the earth.

If the current situation continues, human civilization may be completely wiped out by the earth in thousands of years. In fact, we are not so special or so great. We are just a moment in the history of the earth, not worth mentioning at all, a short-lived civilization.
