What is the origin of life? What is the origin of life?

There are many theories about the origin of life, and the mainstream is also easy to accept the theory that life originated from the ocean, and the inorganic molecules of the ocean and atmosphere formed simple organic matter in harsh environments such as lightning and high temperature, and these simple organic matter gradually formed complex organic micro-clusters, and then formed primitive simple life, which continued to accumulate and gradually evolved into a colorful life world.

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.

Scientists believe that the first step in the origin of life was that proteins that could replicate themselves – later found to be DNA – surrounded by a thin membrane called a bubble. Appel, in collaboration with his colleagues, has been able to use the material components of the early Earth to create such bubbles in freshwater, but not in saltwater.

Life originated in the oceans, evolved from single-celled organisms to marine organisms, and then to terrestrial organisms, learning to walk upright.

The origin of life is of biochemical origin.

The process is the evolution of life on the earth from non-living substances through extremely complex chemical processes over an extremely long period of time after the temperature of the earth gradually drops.

Creatures can spawn 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, and fish withers beetles".

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. Spontaneous generation is a widely popular theory in the 19th century, which holds that life arises spontaneously 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.

Stage:

The first stage, the stage of generating organic small molecules from inorganic small molecules, that is, the chemical evolution process of the origin of life, was carried out under primitive terrestrial conditions. It is important to note Miller's simulations. In this experiment, a roasted canopy containing an aqueous solution represents the primordial ocean, and its upper spherical space contains a "reducing atmosphere" of hydrogen, ammonia, methane, and water vapor.

In the second stage, biological macromolecules are generated from small organic molecules. This process occurs in the primordial ocean, that is, amino acids, nucleotides and other organic small molecules, after long-term accumulation, interaction, under appropriate conditions (such as the adsorption of clay), through condensation or polymerization to form the protein molecules and nucleic acid molecules of the primitive children.

In the third stage, a multimolecular system is formed from biological macromolecules. How did this process come about? The former Soviet scholar Obalin proposed the agglomeration hypothesis, and he experimentally showed that when proteins, peptides, nucleic acids and polysaccharides are placed in a suitable solution, they can automatically concentrate and aggregate into dispersed spherical droplets, which are aggregates.

Obarin et al. believe that aggregates can exhibit life phenomena such as synthesis, decomposition, growth, and reproduction.
