Translator: Maysoon Abbas Auditor: Anwar Dafa-Alla How old is the Earth? Well, by counting the number of radioisotopes In a sample of rock Which is subject to radioactive decay, Geologists estimate the day Earth was born, When it was first formed from Nebula, To be 4.6 billion years ago. But how true is that? Here are some measurements That may help you understand. For example, let’s imagine the entire history of the Earth Until today As a single calendar year. Earth begins to form on January 1. By March 3rd, there is the first clue For single-celled bacteria. Life remains surprisingly single-celled until November 11 When the first multicellular organisms come, Known as the Eidkarian animals. Soon thereafter, on November 16 at 06:08 PM The & quot; Cambrian explosion & quot; for life, A major milestone, When all the people of modern beings began to appear.

On December 10th at 01:26 PM, The first development of dinosaurs But it was erased by an asteroid Only two weeks later. The Great Roman Empire rises and falls on December 31 In just under four seconds. Sailing Columbus To what is believed to be India Three seconds before midnight. If you try to write the history of the Earth With only one page per year, Your book will be 145 miles thick. This is more than half the distance To the International Space Station. The story is 3.2 million years old Fossil australopithesine known as Lucy Will be found in 144 miles, 500 feet from the end of the book. The Declaration of Independence of the United States of America will be signed In the last half inch.

Or if we compare geological time With a woman extending her arms Six feet wide, The simple act of trimming her nails It will remove all recorded human history. Finally, let us imagine Earth’s history as your private life: From the moment she was born To your first day in high school. The first word that I spoke, Sitting for the first time, And the first time you walk All will take their place while life is on Earth It consisted of single-celled organisms. In fact, the first multicellular organisms Did not develop until you are 12 years old And the seventh grade started, Immediately soon from When your teacher for science he says to the class How fossils formed.

Dinosaurs do not appear Until three months into the eighth grade It was erased close to the spring break. Three days before the ninth grade starts, When you realize that the summer is over And you need new school supplies, Lucy, Australopethicene, wanders around Africa. And when you finish breakfast And go outside to catch your bus 44 minutes before school, Neanderthals will die out across Europe. The latest glacial period It ends when your bus drops you off 16 minutes before the start of the semester. Columbus sails 50 seconds before class And you are still trying to find the right row. The independence declaration was signed & quot; 28 seconds after that You are looking for an empty seat. And you were born 1.3 seconds before the bell. So, you see the ground and it is Incredibly old too Compared to us humans With a fossil record Hides incredible stories to tell us about the past And maybe the future too.

But in the short time we were here, We learned a lot We will definitely learn more For decades and centuries to come It is close to moments in geological time.
