What is the origin of life?

There are many speculations, assumptions and controversies about this problem, which is a major problem that modern natural science is trying to solve. Now the academic circles generally accept the theory of chemical origin based on the Origin of Species and Miller's experiment. With the deepening of understanding and the discovery of various evidences, people will study the origin of life more deeply.

Creationism (or creationism):

Creationism holds that everything in the world was created by God. Like God and Achilles. The Bible says, "In the beginning, God created heaven and the earth. The skeptics of creationism believe that the root of creationism is the analogy with human manufacturing ability and the wrong application of probability theory. For example, the probability that religious people form themselves with watches is zero, and a watchmaker must prove that people are created.

They think that the fundamental mistake of this kind of reasoning is that he doesn't understand the self-organization phenomenon that is common in nature (for example, snowflakes and sand dunes automatically form certain regular shapes under certain conditions, which is obviously not intentional by a senior subject and cannot be inferred by probability theory). The most fundamental feature of life is self-organization, not being made.

Extended data:

With the help of weak radio waves, scientists "captured" a carbon-based molecule with a special branch structure from a huge nebula 27,000 light years away, just like looking for a needle in a haystack. These organic molecules far away from the center of the Milky Way indicate that organic structures such as amino acids that make up the structure of life may have originated in the vast space.

According to a report in Science Daily on September 29th (Beijing time), Anade Beckcher and Carl Manton from Max Planck Institute of Radio Astronomy cooperated with holger Miller/Mueller Garaude from Cornell University to conduct full-spectrum measurement on B2 region of Sagittarius, looking for new organic molecules that may exist in space.

Finally, the radio waves emitted by isobutyronitrile were captured in the B2 star-forming region of Sagittarius near the center of the Milky Way. The research team used the Atacama MMW/submillimeter array telescope (ALMA Observatory) in Chile. Alma is located in the Atacama Desert in Chile and is known as the "dry pole" in the world.

It is a radio astronomical telescope composed of 66 sensitive radio parabolic antennas. It is these cooperative telescopes that constitute the sharpest "eyes" in the world, and their sensitivity and resolution are much higher than other equipment.

Rob Garaude, a senior assistant researcher at Cornell University's Center for Radio Physics and Space Research who participated in the research, said: "Usually, the organic molecules found in this star-forming region are single-chain structures composed of carbon atoms, but the isobutyronitrile discovered this time has a branching structure, which breaks this convention."

"This means that complex chemical molecules can be formed in interstellar space and may land on the surface of the planet." Garaude said, "The isobutyronitrile discovered this time has a carbon branch structure, which is the common feature of amino acids and other molecules necessary for life in protein.

This also shows from another angle that the key molecules of life, such as amino acids, may have been produced before the formation of the earth or during the formation of stars. "

With the help of ALMA spectral analysis, the researchers identified about 50 kinds of isobutyronitrile and 120 kinds of linear cyanide in B2 area of Sagittarius. This is the first time that people have found such a large number of chemical molecular structures in the observation of star producing areas, which is helpful for people to "know" all kinds of organic molecules around us again.

Studying the production process of organic matter in the early stage of star formation may help people gradually discover the long and mysterious course of chemical molecules from simple structure to complex structure, from inorganic structure to organic structure that may give birth to life. It may eventually help us understand the mystery of the origin of life.
