Why is there life on Earth???

Known planets have no life on planets other than Earth? Is life so extraterrestrial in the universe still unknown? Life on Earth evolves through the collision of molecules, as long as there are the right conditions (water) and enough time to evolve Our sun can continue to burn for billions of years, and the earth is in a suitable position (if the near point turns out to be the same as Venus, and the farther point will be as cold as Mars, the water will freeze into ice, and the solar system just has the elements needed for life.

There is also extraterrestrial life, which I personally think exists only because it is too far away from us, and it is very likely that a planet similar to the Earth like Glitzer 581 will have life, but it is 20 light-years away from the Earth, how do we know if it has life?

Because the probability was drawn at the time of the lottery, and then we named her Earth. We are at the top of the pyramid of probability, where heaven and earth are unkind, and everything is a dog. Not for Shun to survive, not for business.

Therefore, we have to be worthy of ourselves to come to this world. Not only people, but also lives should be worthy of themselves. It may be eaten by the weak as soon as it is born, but this does not go against the pursuit of life.

The Dharma path is impermanent. Life is a luxury.

Assuming that there really is a God, then whether the first cell will be created by God, whether it will be God who guides the evolution of the cell, this is not certain

The conditions for the existence of life on Earth:

External conditions: a relatively stable and safe cosmic environment.

1.Stability of the sun – provides light and heat.

2.Safe interplanetary space – orbits are coplanar and codirectional, and large and small planets go their own way.

Self Condition: Temperature – The Earth is at a moderate distance from the Sun, making the average temperature on the Earth's surface moderate.

Necessary for life: Atmosphere - The volume and mass of the earth are moderate, allowing a large amount of gas to accumulate and form an atmosphere.

3.Alteration of the composition of the atmosphere by the action of organisms: water-crystalline water vaporization of the primordial ocean.

The period of earth formation refers to the geological time from the solidification of molten material on the surface to the formation of sedimentary rocks, which is manifested as:

1.The molten material solidifies and shrinks, forming rift valleys and mountains on the surface. Cosmic celestial bodies collide, forming large potholes on the surface.

2.As the temperature decreases, the flow of water generated during the solidification of the molten material converges into the rift valleys and large potholes, and the resulting gas remains on the earth's surface, forming an atmosphere.

3.The Earth's core captures the unevenness of the cosmic matter, and the uneven temperature of the earth's surface produces atmospheric flow.

4.During this geological period, gullies, mountains, and large potholes were formed on the surface, and with water and atmosphere, weathering, denudation, and transport occurred, and sedimentary rocks began to form.

5.Primitive life proteins appeared, and prokaryotes (bacteria, cyanobacteria) evolved

No! Think about it, there are countless planets in the huge universe, how can there be life only on the earth? It's just that with our current level of technology, we can't find extraterrestrial life.

But planets like our Earth with highly developed intelligent beings like humans may be just a handful! Because for a planet to evolve into advanced intelligent beings like us humans, it needs a long period of stability on the planet without destruction and cataclysm, and it just so happens that our earth has such conditions! It can be said that this is a great deal of chance!

Therefore, the proportion of planets with highly developed intelligent beings in the universe is not very high, and the huge distance between the universe has become an insurmountable obstacle to the interconnection of intelligent beings, so even if there are aliens, it is difficult for us to find out! I am pessimistic about this, and I believe that human beings may only be able to exist alone in the universe until the end comes!

In addition, the sun on which we live is nothing more than a very ordinary star, and there are countless stars in the universe! According to the latest research by American scientists, our galaxy alone is estimated to have 2 billion planets like the Earth! Therefore, it is safe to say that there are countless planets in the universe that are suitable for life!
