Assuming that the lifespan of the earth is only 1 year, how many seconds can we humans hold out? A history of the evolution of the earth, a bitter tear of life! Let's take a look at what the earth has experienced from the birth of the earth to the present.
According to scientists' analysis, the Earth has existed for 4.6 billion years. What if we compressed these 4.6 billion years into 1 year?!
Primordial Earth
In the early hours of Jan. 1, New Year's Day, the solar system (about 4.6 billion years ago) was in chaos, and countless dust and nebulae gathered into clumps under the influence of gravity. The earliest earth formed, oh no, should be called a fireball more appropriately.
Two days later (about 4.57 billion years ago), the Earth and other planets collided, and the Moon was born. This collision is a lifetime, and it has been guarding the side of the earth since then, until now.
On March 4, water from meteorites (about 3.8 billion years ago) formed pristine oceans on Earth.
On April 4, (about 3.4 billion years ago), the first life was born near the crater in the depths of the ocean: prokaryotes
On April 20, (about 3.2 billion years ago), cyanobacteria, the ancestor of plants, began to appear and produce photosynthesis, releasing oxygen.
Earth during the Ice Age
On June 30, Earth's first ice age (about 2.3 billion years ago) came, the 300 million-year-long Huron Ice Age, the longest since the birth of the earth.
On August 9, eukaryotes appeared (about 1.8 billion years ago), increasing the variability of species and greatly advancing the rate of evolution.
On September 25, (about 1.2 billion years ago), the emergence of multicellular organisms brought about a major breakthrough in biological evolution, at the same time: the Rhodinia supercontinent was formed, when the seven continents were still one.
Cambrian: Trilobite fossils
On November 16, (about 542 million years ago, 542-4.85) Cambrian: a biological explosion, during which many invertebrates "suddenly" rose.
On November 20, (about 485 million years ago 4.85-4.4) ordovician: the first mass extinction, gamma-ray bursts destroyed the atmosphere, and more than 60% of the organisms "disappeared".
On November 24, (about 440 million years ago, 4.4-4.1) Silurian: After the mass extinction of organisms in the late Ordovician period, the surviving organisms slowly recovered and vertebrates began to appear.
On November 27, (about 410 million years ago, 4.1-3.5) Devonian: The Age of Fish, amphibians appeared, and some animals began to move to land.
Giant Centipede of the Carboniferous Period: up to 26 meters in length
December 1, (about 350 million years ago 3.5-2.95) Carboniferous: Giant insect age: land plants appeared in large numbers, plants died after precipitation, slowly transformed into today's "coal", so named Carboniferous; during this period the earth's oxygen content was once as high as 45%, so insects are very large.
December 6, (about 295 million years ago 2.95-2.5) Permian: the third mass extinction, and the worst. Appeared 251 million years ago at the end of the Permian, causing 90% of marine life, and 75% of terrestrial life, to disappear from the Earth.
December 9, (about 250 million years ago 2.5-2) Triassic: a period of reptile prevalence, mammals appeared, and dinosaurs slowly rose.
Jurassic dinosaur fights
December 13, (about 200 million years ago 2-1.45) Jurassic: The heyday of the dinosaurs, dinosaurs relied on absolute body and force, ruling the earth. The largest dinosaur, "Fragile Diplodocus", was 50 meters long and weighed more than 200 tons.
On December 17, (about 145 million years ago, 145-0.65) Cretaceous: The heyday of the dinosaurs, planetary impacts led to the fifth mass extinction, and the overlord who ruled the earth for hundreds of millions of years came to an end
A living fossil of the late Cretaceous period - dinosaurs
On December 24, (about 0.65-0.23 million years ago) crocodiles stubbornly escaped the last extinction, and we were fortunate to see living fossils from this dinosaur era. After the rapid rise of mammals, primates appeared, the ancestors of cetaceans began to march into the ocean, and angiosperms gradually flourished.
On December 27, (about 23 million years ago, 0.23-0.016), mammals continued to grow and develop, and in addition to the extinction of some ancient species, flora and fauna gradually formed a basic appearance.
Australopithecus australis
At 15:00 on December 31, (about 5 million years ago) Australopithecus appeared, the ancestor of modern humans. It is also the more mainstream view of the current academic community.
At 22 o'clock (about 2 million years ago), no one appeared, followed by Homo erectus and Homo sapiens.
At 23:30, about 500,000 years ago, humans basically completed the transition from apes to humans and began to learn to use fire.
The transition from ape-man to man
At 23:59, about 10,000 years ago, the Neolithic age began, and human civilization made great progress.
At 23:59:34, about 5,000 years ago, the three ancestors of China, the YanDi, the Yellow Emperor and Xuan You, founded the Chinese civilization.
23:59:46, about 2070 years before the establishment of China's first dynasty: the Xia Dynasty.
23:59:58, 109 years ago, China's last dynasty: the fall of the Qing Dynasty.
At 23:59:59, you were born...

This second is 146 years, can you survive this 1 second in your life? What are you thinking when you see this? Few people sit still and think about what is the meaning of life? It's a house, a family, or money. Everyone comes into the world in a fleeting moment, in this short time, you can't take anything away, and eventually it will turn into dust and everything will return to zero. Try to live the way you want, at least without regrets!
