I believe that just the right temperature and environment may not be able to produce life, but there must be some kind of mutation that produces life. I believe that the birth of life will never be inevitable, but accidental.
As for whether this mutation is controlled by other advanced intelligent beings, I prefer to believe that this is not true, otherwise we are really no different from guinea pigs.

What life is, why do living beings think, and nothing else does. I've always wondered, where are the memories of people? In what form and why it exists, I've always been confused. Mine , I'd like to ask for advice.

I'm inclined to regulate with highly intelligent creatures, or the probability is .........
-
So arrogant? I'm neutral, and in short, I believe that there are other advanced intelligent life forms that are more likely to be empty.
Who made me a sci-fi fan?

Praise your imagination, I think you have read too much science fiction and comics, ......

Summary. The theory of the origin of marine chemistry holds that in the early days of the formation of the primitive earth, there were some simple organic molecules in the ocean, which could self-assemble into more complex molecules under certain conditions, and eventually evolve into life. Therefore, it can be assumed that there are some substances that may have the potential for life formation on the primitive Earth, but there is no direct evidence of the existence of life on the primitive Earth.

Did Miller think there was life on the primordial earth?
The Miller experiment is a classic voltaic chain experiment designed to simulate the environment of the early Earth. In this experiment, Miller used a reaction chamber filled with water and gas and heated it to produce lightning. Through this experiment, Miller successfully synthesized a number of organic compounds, including amino acids and other molecules needed for life.
While this does not prove that life must have existed on early Earth, it does suggest that molecules with leakage can form naturally under the right circumstances. There is no conclusive evidence for the existence of life on Earth in the early days, but scientists are continuing to search for clues and explore the mystery of the origin of life on Earth.

1. Water is a good solvent, and seawater contains many kinds of inorganic salts necessary for human life.
Such as chloride, carbonate, nitrate, phosphate.
There is also dissolved oxygen, and primitive life can effortlessly draw the elements it needs from water.
2. Water has a high amount of hot melting, coupled with the huge body of water, the temperature change of seawater is relatively small, so the huge ocean is like a natural incubator, is a hotbed for primitive life.
3. Although sunlight is necessary for life, it is the ultraviolet rays in sunlight.
However, there is a danger of strangling primitive life, and water can effectively absorb ultraviolet rays, thus providing a natural barrier for primitive life.
4. It is not accidental that life is born in the ocean, and the physical and chemical properties of the ocean make it the cradle of primitive life, and life born in the ocean will not have the worry of water shortage.

2.(1) Have a suitable temperature. The drop in the temperature of the Earth's surface provides the necessary conditions for the development of life.
2) There should be small molecules that form organic matter. The original atmosphere contains hydrogen, ammonia, methane, and water vapor, among others. (3) It is necessary to have the energy needed for the change of matter.
Lightning, ultraviolet light, etc., provide energy for the change of matter. (4) It is necessary to have a micro-environment that nurtures life. The water environment formed by the pristine ocean became the cradle of life.
The primordial ocean provided the environmental conditions for the accumulation of organic matter, the formation of polymolecules, and the evolution of primitive life.

It is generally believed that the process of life generation can be roughly divided into three stages: the first stage is the chemical evolution stage, which is mainly composed of simple organic monomolecule tung spikes and organic macromolecules. At this time, amino acids, nucleotides and other compounds are polymerized in the primitive ocean to gradually form more complex organic matter.
The second stage is the process from chemical evolution to biological evolution, in which a multi-molecule system based on proteins and nucleic acids composed of multiple organic macromolecules is completed, so that the evolution of life reaches a new stage - the evolution of life in the biological sense. So the real meaning of the life of Wu Bu is realized in the primeval ocean.

<> explanation: There are many theories about the origin of life, but now scientists generally believe that the origin of life is divided into three steps The first step is that under certain conditions, various components in the atmosphere on the primitive earth can be transformed into organic small molecules The second step is to synthesize organic macromolecules such as proteins and nucleic acids from organic small molecules The third step is: with the evolution of natural conditions on the primitive earth, the organic macromolecules on the earth gradually accumulate in the primitive ocean, and through long-term interactions, they are finally gradually formed with the ability to grow, reproduce, The inheritance of primitive life and the further formation of primitive single-celled organisms as shown in the figure is a schematic diagram of the process of the origin of life
Therefore, the answer is: organic small molecules, proteins, nucleic acids, organic macromolecules, growth, reproduction.
Esterification reaction: The reaction of carboxy-COOH and hydroxy-OH to form ester bonds by removing one H2O is an esterification reaction. It is important to note that esterification is also a substitution reaction. >>>More

The plant body contains many kinds of compounds, which are all made up of different elements. What elements exist in the plant body, after the plant body is dried, it is fully burned. When burned, the carbon, hydrogen, oxygen, nitrogen and other elements in the plant body run away in the form of carbon dioxide, water, molecular nitrogen and nitrogen oxides. >>>More
