 Introduction of Life begins on earth -

How modern we humans are today, we can go outside the earth, can see millions of light-years in space. We have science which gives us answers to our questions, through scientific data, we have estimated our existence to a great extent. Earth is our home where we humans have spent many generations who have given shelter to live for many crores of years and continue to give shelter even today. According to scientists, there are about 8700000 species of organisms on the earth, out of which only 15% species have been discovered till date. But finally, where did all these animals come from? After all, to know how life started on Earth We have to go back in time, when the earth was in its initial state, let's go. 

Story of Life Begins -
About four and a half billion years ago - a very large ball of rock was circling an unnamed star. Its surface was made of molten lava and there was no sign of life on it. At this time, small rocks were raining on the earth continuously from the sky,

this process continued for a long time. After this, the circle of rock took the form of a planet as well as this planet made its own moon. This is the same planet where we all live today. At this time the temperature of the Earth was very high. After a long time, the temperature of our planet cooled down a bit and a solid surface was formed on it. 

Astroids Fall on Earth -
About 3.9 billion years ago it again faced the rain of fire shells which we call, The Late Bomb BardMant. And this verse was not only small rocks on the earth, but along with it meteor bodies were also raining many thousands of meteor bodies every day. These meteorites brought with them something very special, there were frozen ice crystals inside them which formed the oceans on our earth and also brought nitrogen gas in the earth's atmosphere, but the earth is still without life, life here Conditions had not yet been made suitable for the Earth, it was completely filled with poisonous gas, there was no oxygen in the atmosphere and the sea was everywhere from the earth. Area was surrounded | But now circumstances were going to change here.

First Life Begins on Earth -

About 3 billion years ago, meteor bodies once again started to rain on our earth, but now these bodies did not only bring water with them, but they brought some very precious things to the earth. This body was supposed to give life, it had brought minerals or minerals along with it, they also transported carbon proteins and amino acids from space to the depths of the sea, but here the sea the temperature was very low in the depth of the sun, here the sunlight could not reach but here even in the depths of the sea, from the small natural chimneys which were keeping the water warm even in the depth and here we did not know that the first life of life flourished. Is how it happened, but somehow here all those minerals and chemicals sow the seeds of life by reacting among themselves and the first one of the unicellular organisms was born here. There were many types of bacteria, they started growing very fast  in the sea, now this water was completely filled with a unicellular organism.

Bacteria's Formed On Earth -

After several crores of years,  about three and a half billion years ago, the number of these bacterias inside the sea had increased so much that they were folded together and turned into structures like stones called Stromatolites. photosynthesis. In the same process, these products used to remove a by-product, a gas oxygen. These micro-organisms created one of the most precious things on earth, which was the most important for life in the earth, and in fact there is no living on earth without it. Could remains.

This rock was a complete colony of bacteria in itself. These bacteria used to convert sunlight into food and we know this process better in the name of

Continents Formed on Earth -
For about 2 billion years, the amount of oxygen in the earth's atmosphere started increasing continuously. About one and a half billion years ago, there were no continents in the earth yet and there only small rocks on the earth of such a big continent. Those who were surrounded by water from all sides but now the earth started to stir, due to this, the surface of the earth broke into many tectonic plates, it is due to the movement, all these little ones have joined again and formed a supercontinent. At this time the temperature of the Earth was 30 degrees Celsius.

And one day of the Earth was 18 hours, but now the conditions were going to change with time,

Earth condition -
About 75 years ago, the outline of the Earth was changing, the supercontinent of the Earth now broke in two and the lava beneath the Earth with the volcanic eruption The amount of carbon in the Earth began to rise, the line was changing. The supercontinent of the earth was now broken into two parts and the lava beneath the earth was hit with a volcanic eruption. Due to these explosions, the amount of carbon dioxide in the Earth started to rise on the surface of Ti, now the sky of the earth was surrounded by dense clouds of carbon dioxide, these acids started to cause acidic rain. The carbon dioxide was roasting on the rocks of the earth with the rainwater as the thick of carbon, due to which the carbon dioxide in the atmosphere The the temperature of this earth could not be able to stop the heat of the sun and the temperature of this earth started to decrease very fast and the first Ice Age started on the earth or it was the longest ever but it was also not going to last forever. At that time, the amount of carbon dioxide in the atmosphere started increasing again and the temperature of the Earth started to decrease again, it slowly started to accumulate on the earth. 

But those single-cell

What happened to the bacteria that were in the sea before today's arrival?

Nearly 40 million years from today - when we go inside the sea at this time, we get to see a completely new world. A cellular organism had evolved here and there were such strange plants, all of which were marine plants. They were small marine creatures, as well as new species that evolved from a single-celled microorganism. It was found that it was only 5 centimetres long but they have some very good growth in their body. They had developed which was later to become an important part of our body.

This was the first organism that had a backbone and developed from these, we were going to get this speciality too.

About 400 million years ago, now the earth had become somewhat familiar, the supercontinent of the earth was broken in many more parts, But the living organisms did not come due to the harmful effects of trees and plants. ozone Absorb ultraviolet rays of oxygen sun, Who created a sheet around the earth that protects us from the ultraviolet radiation of the sun even today, because of this, tiny creatures have come to the surface of the earth and this is the first time that the earth has lived in the sea and decided to come out of the water for the first time. Over time, it started living on the land for a long time, due to which, after the developmental order of about one and a half crores, these animals had become fully habitable in the land and they It was called  Tetrapods 

A new continent was being formed in the atmosphere of Bharat Earth, which we call today and

These tetrapods were fully developed.

36 million years ago and now they have become fully living organisms. These were the creatures that were going to develop into dinosaurs, mammals and finally humans. New species started but now the bad time of the earth was about to come, the development process of the creatures continued with time, but at the same time the environment of the earth was also changing very fast once again. Due to the volcanic eruption, the temperature of the earth increased very much, it caused a huge famine on the earth, in this famine, almost all the trees dried up and the total of 95% of the population of the animals on the earth got cleaned up. Almost all the trees have dried up in the Christian era and 95% of the total population of living beings on the earth has been cleaned, only few things survived in this period, who started eating anything to stay alive lived underground to escape the heat and improved conditions and with time became normal earth atmosphere.

Nearly 200 million years ago, the outline of the earth had changed to a great extent now, volcanic eruptions created new parts, which together formed a supercontinent.

Now the earth looked much like from space today, after passing such a large size, the earth was back to normal, new trees started growing again on the surface and the five husbands on the earth had developed And was born a completely new person who was going to rule the earth in the future. Dinosaur was actually, a 5% creep Those who were able to save themselves in that famine in some way, many species of dinosaurs were also vegetarians, some carnivores, some dinosaurs were of very calm nature, some very violent dinosaurs also for a very long time. Ruled for 11 million years, they were flourishing on the earth.
After this, what happened where all the dinosaurs became extinct and where humans came from, we will know in the next article click here...
