How did life begin on Earth? Science and my thoughts

avatar

After our earth was created, an environment suitable for life was created. The Earth was born from the raw material left over from the creation of the Sun. After the creation of the Sun, our Earth was slowly formed from the dust, gas, etc. that was swirling around. The world we see today as a safe haven was not the same after the creation of the world. Earth has had to deal with extreme weather in the past, scientists say. It took billions of years to create the right environment for life on Earth. Today we will learn about how life began on earth. I think today's topic is going to be very interesting.

If we study what happened after Earth's creation (4.5 billion years ago), we find that volcanoes formed our Earth's primordial atmosphere and once formed the oceans. We also learn that the early atmosphere had almost no oxygen. How will there be oxygen then no plant was born which produces oxygen? Earlier, plants were supplied with oxygen after birth. From this, we understand that plants were created before animals were created. All of us animals take in oxygen and excrete carbon dioxide. So first plants provided oxygen and animals started taking it. Also, the early Earth did not lack carbon dioxide, which plants began to take up after birth because it could be produced in various ways.

Since there was no oxygen in the atmosphere at that time, the earth was repeatedly hit by any comet or asteroid. Our Earth's atmosphere currently contains oxygen, which is why an asteroid burns up to ash and vapor upon entry into the Earth's atmosphere before it hits Earth. Our atmosphere protects our planet in this way. However, most of the Earth was melted by asteroids and comets after Earth's creation. Scientists theorize that a massive planet called Theia collided with Earth and that our Moon was born from the debris of this collision. I support this view of scientists because there are very good arguments behind it. As the Earth was undergoing many collisions, it became very hot. As a result the volcano was formed and was active.

Before the creation of the moon, the motion of the earth was not stable. Hostile weather and storms prevailed all over the world and the world was moving very fast. As a result the days were very short. When the moon was formed the earth began to move at a controlled speed. At the time of the moon's formation, its position was very close to the earth. Later, the Moon gradually moved away from the Earth and is now at a beautiful distance, allowing our Earth to create a suitable environment for life.

Earth was created 4.5 billion years ago and life began to exist on earth 3.5 billion years ago as evidenced by scientists from some early fossils. Some essential materials were needed for life to exist on earth. Like water, carbon etc. Earth was bombarded by so many comets that the comets filled the oceans with water. Carbon was not created on Earth but came from other planets and that is in the medium of comets. Then comets were very important in creating life on earth because they brought the necessary materials or building blocks for life to earth.

Comets are to be thanked because they brought the building blocks for life. This comet shower destroyed life on Earth when life was fully formed. Both life-giving and life-destroying qualities of comets are observed. Just when dinosaurs were living and dominating the earth, the comet shower killed 75% of the dinosaurs. Many more animals lost their lives during that time but all the animals that lived in small holes survived. Man appeared on earth much later. I think some animals became extinct in the world to create the right habitat for some new ones. If primitive animals were living today, we humans might not have taken over the earth and lived like this.

We know that an animal is made up of countless cells. Scientists now believe that it is impossible for so many cells to be created simultaneously to form an animal. So they made an idea about it which is that first a single cell was formed and then other cells were born from it. The concept is controversial. We see cell division in the animal body which is the process of producing multiple cells from one cell in animals. Through the process of cell division, two cells are born from one cell in the animal body, thus many new cells can be born in the process. But now the question remains that how can a cell have a life or how can a cell survive in the environment and have their life? I think scientists don't know the answer to this question.

One of the two proposed ways of creating life is that one cell is formed and then many cells are formed around it. Another idea is that life is created from all cells simultaneously. According to the scientists, the second idea seems more acceptable. They think that the basis for life arose from carbon-based chemistry that was carried by comets. I think so too. Everything that is needed to create a life comes together in a complex process to create life simultaneously. It is not possible for a single cell to survive in nature and form all the body parts of an animal where animals are multicellular.

However, not just one animal was created in the beginning. Innumerable lives were created in the same process I think. The climate at that time may have been perfect for the process of animal creation. Scientists are very skeptical about animal creation because there are no animals from that time, now alive, from which research suggests that animals were created this way. Now they may not have anything to do except give theory. Scientists researching how animals originated may reveal new information. But it is my opinion that all parts of an animal were created simultaneously.

What do you mean about creating all parts of the animals at the same time?

I mean all the organs of the animal body like kidney, heart, lungs and other body parts. thank you

This is interesting @momins. When I look at the various animals, etc, living on the earth it is amazing…like they were created and placed here. So true the inside workings of humans and animals are basically all the same.
