The Earth was born 4.6 billion years ago, and if human history is integrated into this long time, it takes only 8 seconds. This makes people can't help but have unbelievable questions, alarmist wordsIn order to delineate this long history more clearly, people divide the 4.6 billion years into Archean, Proterozoic, Paleozoic, Mesozoic, and Cenozoic periods. The Paleozoic Era covers 5700 million to 2500 million years, divided into Cambrian, Ordovician, Silurian period, Devonian, Carboniferous, Permian and other stages;The Mesozoic Era spanned 2500 million to 65 million years, including Triassic, Jurassic, Cretaceous;The Cenozoic Era, on the other hand, is divided into Paleogene, Neogene and Quaternary from 65 million years to the present. Each period has left behind fossils of organisms that allow us to analyze the age to which the strata belong.
In order to better understand the weak proportion of human beings in the long river of geological history, let's take a 12-hour clock as an example. In this clock, 2:15 marks the boundary between the Proterozoic and Paleozoic eras, 5 years ago700 million years. Prior to this, life existed in the form of bacteria for a full 4 billion years, and at this moment, life suddenly exploded, forming a multitude of organisms, which is the beginning of the Paleozoic era. 7:30 marks the alternation of the Paleozoic and Mesozoic Eras, and at the end of the Permian, the United Paleocontinent began**, leading to the extinction of 70% of all living things. This was followed by the Triassic period of the Mesozoic Era, which lasted for a full 3 and a half hours, from 7:30 to 11:00, when dinosaurs and reptiles ruled the earth. 11:00 marks the end of the Cretaceous period, when an asteroid hit the Earth causing the extinction of the dinosaurs and the Earth entered the Cenozoic Era, the period when mammals and angiosperms ruled the Earth. Based on the calculation of 1 million years of human history, compared with the 12-hour biological clock, the results are incredible, and the survival time of human beings is only 8 seconds.
This illustration of the Earth's clock is a more vivid representation of the alternation of different periods and the change of life in the long history of the Earth. From the age of bacteria to the reign of dinosaurs to the rise of mammals, every moment has witnessed the wonders of life on Earth. And in this long history, human existence is like a passing passerby, occupying only 8 seconds of the clock, compared to dinosaurs, trilobites, lobsters, crocodiles, etc., our existence seems insignificant.
Such a contrast makes one wonder what role humans have played in the history of the planetDoes our ephemeral existence have a deeper meaning?The thinking triggered by this earth clock may make us cherish the life in front of us even more, as well as our common home, the earth. In this boundless universe, we are like passers-by of time, and the Earth clock is a silent observer who witnesses this process.
Through this unique perspective of time and space, we deeply feel the inexorable passage of time and the vicissitudes of the earth. Instead of dwelling on the trivial life of day after day, it is better to step out and look at our existence with a broader perspective. The history of the earth is so long, and human time is so limited, which is why we should know how to be grateful and treat every fleeting moment. Perhaps, in these 8 seconds, we can create more miracles and leave better memories for this generation of witnesses on the earth.
Eventually, when we look up at the starry sky and think about the history of the earth, we may be able to understand more truly: we are just a tiny speck of dust in the long river of this universe, but it is precisely because of our existence that this universe appears more colorful. The Earth Clock tells the story of the small and great in this universe.
Commentary: The Smallness and Greatness of Humanity under the Earth's Clock.
This article vividly illustrates the ephemeral existence of humans in the long history of the Earth by comparing the history of the earth and the time of human existence to a 12-hour clock. This unique perspective of time provokes deep reflection and empathizes with one's own weakness and greatness in the universe.
First of all, through a detailed time division, the article divides the 4.6 billion years of earth's history into Archean, Proterozoic, Paleozoic, Mesozoic and Cenozoic periods, so that readers can have a clearer understanding of the evolution of life on earth. This time-layered description provides a powerful foreshadowing for subsequent clock metaphors, allowing readers to better understand humanity's place in Earth's history.
Secondly, by comparing human history to 8 seconds on a clock, the insignificant presence of human beings is emphasized by comparing it to dinosaurs, trilobites, lobsters, etc. This contrast not only makes people lament the inexorable passage of time, but also provokes deep reflection on the role and meaning of human beings. Are humans just a passing moment in the history of the planet?This kind of questioning of the meaning of existence makes the reader feel his own insignificance and preciousness in contemplation.
Further, the article uses the earth's clock as an introduction to the passage of time, the replacement of life, and the role of human beings in this process. Through this unique perspective, the reader is transported into a broader cosmic perspective that transcends the trivialities of everyday life. This way of thinking inspires a reverence for time and a cherishing of life, making people more aware of their own small and precious existence in the universe.
Finally, the article calls on people to cherish the life in front of them more while understanding the history of the earth. In this boundless universe, human beings may be small, but they are also unique. Earth clocks are not only witnesses of time, but also of human miracles. Through deep thinking about time and life, we may be able to create more beautiful moments and leave a deeper imprint in these short 8 seconds.
To sum up, this article resonates deeply with people's place and existence in the history of the earth through unique metaphors and deep reflections. The smallness and greatness of human beings under the earth's clock is a journey of thinking that transcends time and space, evoking people's awe of the universe and their love for life.
