How did life begin on Earth? - The Documentary

Today at this moment you are sitting comfortably and reading this article. But let me tell you that the land where you are sitting right now was boiling millions of years ago at a temperature of 8500 degrees or the place where you are sitting was covered with ice for millions of years.

In this article, you are going to learn about the 450 crore years journey of the Earth.

Formation of Solar System

The place where our solar system is today used to be clouds of different types of gas and dust. With time, the energy of the star started decreasing due to which a huge explosion took place inside it. Due to the explosion, the space dust started pressing each other. During this, due to the pressure and heat, the dust particles located in the clouds started falling into large meteorites and letters. Due to this pressure, the radioactive substances present in these clouds were not created but gravity. Due to this gravity, hydrogen and helium started gathering in the middle. Due to the pressure of youth in the middle, a huge explosion occurred and due to this explosion, The sun is born.

Asteroids and the Formation of Earth

Asteroids scattered in space have come closer to the Sun due to their heavy weight and have started revolving around the Sun. Gradually these asteroids collided. As a result, planets like Mercury, Venus, Earth and Mars were formed.

Due to gravity on the Earth, the asteroids revolving around the Sun now started revolving around the Earth and gradually kept falling on the Earth for millions of years.

Formation of the Moon

According to scientists, at that time a planet named Thea used to be the image of the sun between Earth and Mars. This planet gradually collided with the Earth, due to this collision some parts of the Earth spread in space in the form of particles and started revolving around the Earth. The moon was formed due to the collision between revolving particles.

Formation of Volcanoes

At that time there was only one sea on Earth and that was of lava boiling at a temperature of 1900 degrees Celsius.

With time, the Earth was gradually cooling down, due to which the Earth's heavy elements like metals and radioactive substances gathered in the center of the Earth and the lighter elements came to the Earth's surface. For millions of years, meteorites rained on the Earth and these falling meteorites contained salt, minerals and water.

Gradually the upper surface of the earth became cold with water. According to scientists, this was the time when for the first time micro-organisms were formed from volcanoes emerging deep under water.

After millions of years, there came a time when the upper surface of the earth was covered with water.

Due to the innermost core of the earth being made of radioactive material, every dam keeps getting heated, but whenever the upper ground of the earth gets cold, the heat inside the earth is not able to come out due to which volcanoes are formed.

The eruption of volcanoes on Earth continued for hundreds of years, due to which the part of water above the Earth gradually started turning into a hard surface.

About 300 crore years ago, there came a time on Earth when the Earth's atmosphere became almost stable, volcanoes started erupting and at that time a day on Earth used to last 12 hours.

Oxygen on Earth

About 250 crore years ago, for the first time, such creatures were formed on Earth, so to survive, they used the minerals underwater, and sunlight and exhaled oxygen in the form of defecation. Due to these micro bacteria, the amount of oxygen in the atmosphere was increasing. Due to the increase of oxygen in the atmosphere, the Earth's atmosphere started forming and the amount of oxygen in the atmosphere continued to increase for thousands of years to come.

With the passage of time, cracks began to develop in the Earth's tectonic plate due to which the lava inside the Earth kept boiling openly like the ground for millions of years and this was the reason due to which the amount of carbon dioxide in the Earth's atmosphere increased greatly and Acid rain started on earth.

Due to this, the temperature of the earth started decreasing and the temperature decreased so much that the water on top of the earth started converting into ice. There came a time when the earth was completely covered with white snow.

Formation of Plants on Earth

Due to the arrival of oxygen, the ozone layer of the earth started thickening and about 47 crore years ago, for the first time, a plant called Mosos started growing on the upper surface of the earth. With time, different types of plants and trees started growing on the ground. Happened.

Pangaea or Pangea Supercontinent

Most of the Earth's land had gathered in one place, which we know today as the continent of Pangaea. The Earth's atmosphere and temperature had become almost stable and now the day used to be around 21 to 23 hours.

Existence of Dinosaurs

Now sea creatures started living out of water and the color of their bodies was changing according to the environment and gradually the land animals transformed into dinosaurs. Those dinosaurs who started eating plants, their bodies started growing long and huge and some dinosaurs used to hunt, due to which they became smaller and faster.

End of Dinosaurs

Millions of years ago, a meteorite weighing about 4.5 lakh crores, bigger than today's Mount Everest, was coming towards the Earth at a speed of about 80,000 kilometers per hour. As soon as it touched the Earth's surface, it caught fire and started burning. Hit the earth. The energy released from this collision was equivalent to today's explosion of 10 crore atomic bombs simultaneously. Where this meteorite fell, the animals and trees there immediately turned into steam and as soon as it fell, dust started spreading all over the earth and there was a severe flood in the sea.

Formation of Monkeys

At that time, the creatures that used to live underground or below the ground were successful in saving themselves.

As soon as the atmosphere on Earth started becoming normal again, these small creatures started coming out of the ground. They started wandering in the forests, and gradually these creatures started transforming into monkeys.

But as the temperature on earth started increasing, the forests began drying up. The monkeys started facing a shortage of food in the forest and in search of food, these monkeys started walking on their feet. This helped them a lot in moving from one place to another and in hunting animals.

Gradually the monkeys transformed and in search of food these monkeys started spreading to other parts of the earth and gradually the appearance of their bodies changed according to the weather there.

Gradually the monkeys transformed and in search of food these apes started spreading to other parts of the earth and gradually the appearance of their bodies changed according to the weather there. With time we became tribals, then we invented weapons and fire, and now we gradually evolved as humans and this is how society was formed. Today we are said to be the most developed and intelligent species on earth.

Conclusion

Remember that it took approximately 450 crore years for the Earth to become the way it is today and it took many millions of years for us to transform from a small land-dwelling animal to a human being.

But no species to date has done as much pollution and destruction to the earth as we have done in these years. Now we humans are again polluting the earth due to which the amount of carbon dioxide in the atmosphere is increasing. Scientists believe that huge changes are going to happen again on Earth.

Time will tell what the earth will be like in the future, but we humans will have to take the right steps in the right direction to save the earth and the environment.
