Were there any civilization on Earth before us

 Civilization before us

Our human life evolved from the jungles of Africa about seventy thousand years ago. At that time, we lived in caves, ate wild groundnuts, hunted with ordinary spears and stones, and sometimes we hunted ourselves. But the descendants of the same ancestor who ran through the jungles of Africa yesterday are now parading in space.

would ancient civilization look like this?

Today our food and lifestyle have changed. Today, the same people who live in caves and hang in the trees are flying in skyscrapers and sophisticated means. Today we have reached the zenith of development. Today, we have developed so much that we are imagining building a house on the moon, the satellite of the earth. In addition, we are leading the plan to establish human settlements by exploring and researching other planets in the solar system. Not only that, today we have discovered such secrets of the universe. When there was no knowledge about it, our ancestors would sometimes look at the sky in the dark night and sometimes jump in fear and sometimes in joy. In fact, we have become very modern. But have you ever wondered? Are we the only modern civilization on earth, or have any other developed civilization lived on this earth before us?

You must have imagined this in our minds. So do we have any concrete evidence? Who can give meaning to our imagination?

This Earth is about 4.5 billion years old. It has been living a complex life for thousands of millions of years. However, the existence of human life is believed to have started about 300,000 years ago. Of course, for us, it is a very long time, but for nature, it is like blinking our eyes only once. Maybe there were many modern civilizations here before us. In time, those civilizations may have disappeared. But if there was an advanced civilization before us. 

What kind of civilization was it? How much access was there? And how did those civilizations disappear?

In 2017, Dr. Jason Wright, an exoplanet researcher and associate professor at Penn State University, wrote a paper entitled "Prior Indigenous Technological Species." This article was written on how to find out if there was an advanced civilization in the universe including our earth before us. In addition, there were facts about how civilization became extinct. One thing is for sure, we have been able to find out a lot of facts about the solar system and other exoplanets through some successful space missions, but even today we have not been able to find and study our own earth properly.

With the help of various spacecraft, probes, robots, etc., which have been searching for different planets in the solar system, it has been found that the present condition of these planets is in the first phase. Because billions of years ago, when the sun was not very hot, the nearest the planet, Venus, which is one of the inner planets, was not as hot as it is today. Similarly, Mars was a planet with the same climate as Earth. Billions of years ago, some of the planets other than our Earth that were habitable and had habitable environments may have had ancient civilizations at one time or another.

Adams Frank, a university physicist, and Govin Schmidt, a NASA astronaut claimed in a 2018 research paper about an advanced civilization before today's man, and how to find out if we are the first modern civilization on earth. According to him, we can easily guess the existence of ancient civilization. Because we human beings have not developed on earth for so long. This time is much shorter than the age of our earth. In such a case, an advanced civilization may have existed on this earth at some point before us. These papers also explain how we can find out that we humans are the first advanced civilization on earth. This possibility is called the Silurian Hypothesis.

According to this hypothesis, we are very ignorant about the ancient earth. The oldest part of our planet is the Negev Desert in southern Israel. Which is about 1.8 million years old. Apart from this, no part of the seafloor is more than 170 million years old. Now you may be wondering if there was a modern civilization on this earth before us, why have we not received any sign till today? We know that any old living thing that existed before today. Evidence of this can be seen in the fossil record.

But according to Adams and Schmidt, there is no evidence of any civilization that existed more than 4 million years ago in the fossil record. In other words, it will be very difficult to know that a modern civilization like yours and ours lived here a few million years from now. Because if any civilization really goes extinct, our planet will return to its former state, and the environment, climate and other natural phenomena will destroy the man-made structures. The Earth's natural cycle will erase all evidence that our civilization has created.

We have released 500 billion tons of carbon into the earth's atmosphere in the last few centuries. It has become a letter in our geological record. Which will play an important role in discovering our civilization in the future, thousands and millions of years from now? It was a civilization that would be known as a high carbon-emitting civilization. Not only carbon but we are also emitting things like glass, chromium, and gold. Scientist Jason Wright says that the various objects we have created on other planets in the solar system should be kept safe, even with the latest technologies. Just as the Golden Record in the Voyager spacecraft was designed to be safe for 10 million years. Which has been sent into space to cross the entire Milky Way? So we have already broadcast an interesting video about the Voyager spacecraft. Be sure to check out the link below in the description.

The Arch Mission Foundation is one such group that plans to collect all the knowledge our civilization has acquired to date and store it on the moon. If all goes according to plan, the Astrobiotic Peregrine Moon Lander will be sent to the moon in 2021 with the help of a rocket. In which all the knowledge of human civilization i.e. all the content of Wikipedia as well as a collection of human languages ​​and various other items will be sent in one microfiche. Which can be read with the help of a microscope of 1000 times magnification. Once it reaches the lunar surface, it will be safe for billions of years.

Now you may be wondering what would happen if a meteorite hit this disc? But with that in mind, the Arch Mission Foundation plans to send Astrobotic peregrine moon landers with all the knowledge of human civilization to all the planets and satellites in the solar system. Perhaps these disks will be safe on some planet or satellite. From which the present human civilization will be extinct, but the future human civilization will be able to get information about us and receive that knowledge.

All these researchers have only guessed that the study to date has not found any evidence of ancient advanced civilization. Of course, if we talk about Hinduism, we hear discussions about some relics of the Mahabharata period of the Dwapar era, but scientists have not been able to fully confirm whether the Mahabharata era was literature or a modern civilization.
