How did life come about?

After a new star, which we call the Sun, appeared in the Milky Way galaxy about four and a half billion years ago in space, planets began to appear around this star.

About 40 million years after the birth of the Sun, our Earth also appeared. And at first it most of all resembled a huge red-hot round stone.

Simultaneously with the Earth, other planets of the solar system were formed from the accumulations of matter, dust and gases around the Sun. And one day, 20 million years after the emergence of the Earth, one of the planets, which scientists call Teia, collided with our planet. As a result of this impact, the planet Teia collapsed, and from its debris a satellite of the Earth - the Moon - appeared.

At the same time, comets were constantly falling to the Earth, bringing with them not only destruction, but also water from which seas and oceans began to form on the planet, as well as the atmosphere, i.e. what we see during the day as a blue sky with clouds or a gray sky with clouds.

As a result of all these collisions and falls, a giant space mixer appeared on Earth, constantly stirring the ocean water by ebb and flow, accompanying this mixing with regular and frequent heating during the day and cooling at night.

The Moon was very useful for the operation of this mixer.

The fact is that all cosmic bodies - stars, planets, satellites, influence each other. This influence is called attraction. It is not very easy for an ordinary person to notice this attraction without special devices and knowledge, if he lives somewhere in the mountains or on the plain. But if he lives near the sea or ocean, then he can observe the result of the action of the moon's gravity every day. The ebb and flow in the seas and oceans is precisely the visible result of this impact. The moon attracts seawater, creating a kind of small water bulge at the point of closest approach, which creates an ebb or flow near the coast. When the Moon goes below the horizon, the water ceases to experience its attraction and “flattens out”, which we see in the form of a tide in one place of the globe and an ebb tide in another.

Thus, the water in the oceans is constantly mixing. And if we consider that when the Moon appeared, it was six times closer to the Earth than it is now, then the ebb and flow of the ocean water were much stronger.

Simultaneously with this stirring, the sea water is constantly heated by the Sun and cooled down at night when the Sun is not present. Between the oceans and the resulting atmosphere, gigantic electrical discharges - lightning - constantly slip. Underwater, huge volcanoes bring the ocean water to a boil. It turns out a giant saucepan, into which nature threw everything that it had, constantly warms up, cools and mixes, and even shocks.

And just as borscht appears in the kitchen as a result of fire, water, steam and food, so in nature, life appeared in the giant pan of the Earth. For this, nature had to cook its broth for about 35 million years.

The first living organisms were not at all like dogs and cats, they didn’t look like little men or even dinosaurs. They were tiny bubbles that could only be seen through a microscope. But these were our great-great-great-great-great-great-relatives, who had not even become great-great-grandmothers and great-great-grandfathers yet. Nature will create the division into boys and girls much later.
