Summary. Life originated in the ancient atmosphere: Miller Yuri's experiments showed that lightning may have caused the formation of organic matter in the atmosphere in ancient atmospheres.

Life on Earth can originate anywhere.

Life originated in the ancient atmosphere: Miller Yuri's experiments have shown that lightning may have caused the formation of organic matter in the atmosphere in the ancient atmosphere. Life originated in space:

Life on Earth may be the best asteroid that carries organic matter and even RNA in a circle that hits Earth and brings life to Earth.

There are many conjectures and hypotheses on this issue, and there are many controversies, and it is a major problem that modern natural science is trying to solve.

The theory of the origin of chemistry is now generally accepted by the academic community, which is based on the theory of "The Origin of Species" and Miller's experiments. With the deepening of understanding and the discovery of various evidences, people will have more in-depth research on the question of the origin of life.

Creationism (or Creation Theory):

Creation theory holds that everything in the world was created by God. For example, God, Alcius. The Bible says, "In the beginning God created the heavens and the earth.

Skeptics of creationism argue that the roots of God's creation theory are analogies to man's manufacturing capacity and the erroneous application of probability theory. For example, if a religious believer uses a watch to form itself, the probability of self-formation is zero, and there must be a watchmaker to prove that man was created.

They believe that the fundamental error of this reasoning lies in his ignorance of the self-organizing phenomena that are prevalent in nature (e.g., snowflakes and sand dunes automatically form a certain regular shape under certain conditions, which is obviously not deliberately created by a higher subject, and cannot be inferred by probability theory). The most fundamental feature of living organisms is that they are self-organizing, not manufactured.

Note: With the help of faint radio waves, scientists have "caught" a carbon-based molecule with a special branching structure from a huge nebula 27,000 light-years away. These organic molecules, far away in the center of the Milky Way, suggest that the amino acids and other organic structures that make up the structure of life may have originated in the vastness of space.

According to the daily scientific report on September 29 (Beijing time), Fanlu Anad Beckcher and Carl Manton from the Max Planck Institute for Radio Astronomy collaborated with Holger Miller Muller Garrod from Cornell University to conduct full-spectrum measurements of the Sagittarius B2 region to search for new organic molecules that may exist in space.

Finally, in the Sagittarius B2 region near the center of the Milky Way, the radio waves emitted by isopropylcyanide were captured. The team relied on the Atacama Millimeter Submillimeter Array Telescope (ALMA Observatory) in Chile. ALMA is located in the Atacama Desert in Chile, known as the world's "dry pole".

It is a group of radio astronomical telescopes composed of 66 sensitive radio parabolic canopy car split lines, and it is these coordinated telescope groups that constitute the sharpest "eyes" in the world, with sensitivity and resolution much higher than other devices.

The origin of life, which refers to the question of when, where, and especially how life originated, is a major issue that has not been completely solved by modern natural science, and is the focus of people's attention and debate.

Spontaneous generation, also known as "autopoiesis" or "abioticism", holds that living things can be produced at any time from non-living things, or from some very different object. For example, in ancient China, the so-called "meat rots out worms, fish withers beetles", Aristotle said "......".Some fish develop from silt and gravel." In the Middle Ages, it was believed that leaves that fell into the water turned into fish, and when they fell to the ground, they turned into birds.

The Origin of Life in Detail:

Spontaneous generation is a widely popular theory before the 19th century, which holds that life occurs naturally from inanimate matter. For example, in ancient China, it was believed that "rotten grass turned into fireflies" (that is, fireflies were produced from rotten grass piles), carrion maggots, etc. In the West, Aristotle (384 BC, 322 BC) was a spontaneous genealogist.

Some people have also proved through "experiments" that if you stuff grains and worn shirts into bottles and put them in a dark place, they will produce rats after 21 days, and to his surprise, this "naturally" occurring rats is exactly the same as common mice.

In the 19th century, the French microbiologist Louis Pasteur (found that if the broth is heated in a flask, boiled and allowed to cool, if the flask is opened, many microorganisms will quickly multiply and grow in the broth; But if you add a tampon to the mouth of the bottle and do the same experiment, there are no microorganisms in the broth. Pasteur believed that the little creatures in the broth came from the air, not from natural occurrences. His experiments laid a solid foundation for scientists to further reject the "theory of natural generation".

In 1860, the French microbiologist Pasteur devised a simple but convincing experiment that completely rejected the theory of spontaneous generation.

Life originated in "small ponds rich in organic salts such as ammonia and phosphorus, light, heat, electricity, and other related substances." The theory of the origin of life has always been a matter of debate in the scientific community. Life on Earth may have originated in freshwater ponds, rather than near deep-sea heat sources, as is widely believed in academic circles.

From ancient times to the present day, there are many theories that explain the question of the origin of life. For example, the Western theory of creation, the Chinese theory of Pangu opening heaven and earth, etc. However, it was not until the nineteenth century, with the advent of Darwin's book "The Origin of Species", that biological science underwent unprecedented changes, and at the same time, it also brought a glimmer of hope for mankind to reveal the eternal mystery of the origin of life, which is the modern theory of chemical evolution.

The chemical evolution theory of the origin of life was first confirmed by an American scholar Miller in 1953. That was in the early days, because the Earth contained a large amount of reducing primordial atmosphere, such as methane, ammonia, water, hydrogen, and the primordial oceans.

When lightning on the earth in the early days polymerized these gases into a variety of amino acids, and these amino acids, at room temperature and pressure, it may be locally concentrated, and then further evolved into proteins and other polysaccharides, as well as polymer lipids, which may germinate into life at a certain time, which is the process of life evolution described by Miller.

After the formation of the earth, it began to be inanimate, and after a long chemical evolution, the spontaneous combustion of the organic elements in the atmosphere, hydrocarbon, dust, lead nitrogen, oxysulfur and phosphorus, and various energy sources in the actual synthesis of organic molecules, which were further synthesized into biological monomers. At present, the theory that the origin of life is through the macroscopic process of chemical progress has been recognized by the majority of scholars, and it is believed that this chemical evolution process can be divided into four stages.

Stage 1: The stage in which small inorganic molecules are generated from small organic molecules. The first step in the origin of life is to form organic small molecules from inorganic small molecules, which is entirely possible under the conditions of the primitive earth. The second stage is the generation of biological macromolecular substances from organic small molecule substances, this process occurs in the primitive ocean, that is, amino acids, ribohydric acid and other organic small molecule substances through long-term cumulative interaction, under appropriate conditions, through condensation and polymerization, the formation of primitive protein molecules and nucleic acid molecules.

The third stage is to form a multimolecular system from biological macromolecular substances, and the former Soviet Union scholar 280 put forward the agglomerate hypothesis, which shows through experiments that proteins, polypeptides, nucleic acids and polysaccharides are placed in a suitable solution, and they can be automatically concentrated and aggregated into scattered spherical flakes, these little brothers are agglomerates, and it is believed that the agglomerates can manifest synthetic, decomposed, grown, reproduction and other life phenomena.

The included body has a boundary similar to that of moore, and its internal chemical characteristics are significantly different from the external solution environment agglomerate, which can inhale certain molecules from the external solution as reactants, and can also undergo specific biochemical reactions under the catalytic action of enzymes, and the products of the reaction can also be released from the agglomerate. The fourth stage is the evolution of organic polymolecular bodies into primitive life, which was formed in the primitive ocean, and is the most complex and decisive stage in the origin of life, which cannot be verified in the laboratory at present.
