How did humans come about?

In the early days, there were many substances such as methane, nitrogen dioxide, etc. on Earth. Amino acids are formed under the action of lightning, and then through a series of chemical changes (such as polycondensation reaction, etc.), proteins with life activity are generated, and this is the origin of life. The earliest organisms were unicellular and lived in water (but the sun's ultraviolet rays irradiated the earth very strongly).

When the ozone layer was formed, some aquatic organisms gradually became terrestrial. And among them are the ancestors of the ape-man. That's how living things evolved.

The basis of evolution is variation, and 31,000 individuals in the heredity of organisms will mutate, and most of the variations are harmful to the individual but beneficial to the entire population. Why? Because mutation provides material for biological evolution.

Natural selection leads to the orientation of biological variation, mutating in the direction of beneficial. For example, why do giraffes have long necks? In fact, the earliest giraffes had short necks, but there are very few individuals with long necks in the population.

When the food resources on the ground were in crisis, all the short-necked individuals died, and only a handful of long-necked individuals survived by eating leaves. Those individuals with long necks reproduce offspring, passing on genetic traits to the next generation. Human beings have also evolved to this point through one catastrophe after another.

In Chinese books, which are monopolized by the theory of evolution, man evolved from ape-man. Darwin was obsessed with his own theory of evolution at a young age, but over time he also realized that his theory of evolution was so ignorant and ridiculous in the mysterious forces of the universe, and later returned to God to repent. China's current society is a society dominated by atheism, and it is actually very naïve to regard the theory of evolution as the supreme treasure.

With the progress of science and the development of genes and genetics, there are more and more loopholes in the theory of evolution, and genetic changes are the main reason for the mutation of species and are recognized, but the theory of evolution does not see this, and Darwin once fully recognized that only the environment and the way of survival of the fittest can make species evolve and develop. How genes are mutated or improved is still very mysterious. Many scientists believe that man was created by God, that is, a mysterious force in the universe, and I believe this very much, and to solve the mystery of the origin of man, the theory of evolution must be a mistake.

It started as a marine single-celled organism, then gradually became a multicellular organism, an amphibian, a land reptilian, and then evolved into an ape, and then into a man.

God created Adam and Eve, and after Adam and Eve ate the forbidden fruit, there were human beings.

At present, there are two main theories, namely, evolutionary theory and creationism. Before it was confirmed, it was explained by various myths and legends. Since Darwin founded the theory of biological evolution, most people believe that humans are the product of biological evolution, and that modern humans and modern apes share a common ancestor.

Humans evolved step by step from primates through a long evolutionary process. Human evolution originated from forest apes, and developed step by step from primates through a long evolutionary process. It has gone through four stages: ape man, primitive man, sapiens man, and modern man.

Due to the development of archaeology, prehistoric civilization has been gradually denied, and archaeology has most of the evolved hominin fossils. In conjunction with the discoveries of modern biology, it was discovered that genetic DNA is evolutionary, confirming the authenticity of the theory of neutral evolution.
