Every person in a certain period of his life thought about how people appeared on Earth. Centuries-old attempts to solve this mystery have not yet led to a result, scientists are still arguing on this topic. It is logical that the truth must be sought in the most ancient sources, which are closest to the moment of the birth of life.

Theory one: God created mankind

One of the first legends that sounded authentic were the stories that people were created by the Supreme Mind, that is, God. Many peoples believed that the first people were molded from clay. It is not known for certain why this particular material was considered "human". Most likely, this is due to the fact that clay is a radioactive substance, which is explained by the presence of uranium in the composition, and during decay, it can release significant amounts of energy. The ancestors claimed that this was the energy that was used to create living beings. Legends about the first woman and man are known all over the world.

Theory two: people are hermaphrodites

According to other myths that tell how the first man appeared, people descended from some bisexual creatures - hermaphrodites. Adherents of this theory were the peoples of Africa and Sudan. They believed that the division of people by gender occurred after a huge number of years.

Theory Three: Aliens

Modern versions of how people came into the world associated this fact with the presence of alien life. People believed that unearthly beings came to Earth and artificially gave birth to life on the planet.

Theory four: living cell

For a long time, many scientists rejoiced, believing that they had solved the mystery of how people appeared on Earth. It seemed quite obvious to them that the appearance of mankind is connected with the formation of a living cell.

They built various models when a living cell was born from inanimate matter under the influence of chemical processes. It was claimed that this living particle was in the earth's ocean, which at that time was simply seething with chemical reactions.

Later it was proved that everything necessary for the emergence of life was in space long before the formation of the Earth. Scientists insisted that the appearance of a living cell is a coincidence and unforeseen biochemical processes that explain how 1 person appeared.

However, there were people who actively denied this version, since the content of the genetic code is an abstract record that cannot be predicted. Francis Crick, who was the first to discover the geneticcode, argued that a living cell could not originate on its own. But even assuming that this happened, there is no explanation for why there was such a variety of living forms that arose as a result of a single cell.

The adherents of this theory, how people were born, cited as an example the development of Darwin, who believed that all life was formed as a result of random and chaotic mutations. As a result of natural selection, forms that were unsuitable and unsuitable for life perished. And those strongest who survived continued to survive and develop.

Today, such a theory of how people appeared on Earth does not hold water. Despite numerous excavations, it was not possible to find a single creature from which another creature could originate. If Darwin was right, now we could observe outlandish and amazing monsters.

The recent discovery that most genetic mutations are highly directional has finally disqualified the "chance" theory. And the rest of the mutations, which are caused by disturbances in the body, cannot carry anything creative.

Theory Five: Evolution

The assumptions of this theory are that the ancient ancestors of man were higher primates, or monkeys. The modification had 4 stages:

  • Australopithecines. They walked upright and could use some items with their hands.
  • Pithecanthropus. Fire control was added to other skills. However, the appearance was far awayfrom the human form, the monkey features were quite clear.
  • Neanderthal. The structure of the skull was still different, but the overall skeleton was close to the human.
  • Modern man.

The downside of this theory was that scientists were unable to explain in detail how mutations could contribute to the emergence of complex life forms. Until now, not a single kind of beneficial mutation has been discovered, they all lead to the destruction of genes.

Theory six: Hyperboreans and Lemurians

Esoteric history has its own interpretation of how people appeared on Earth. It is alleged that before modern mankind, the planet was inhabited by huge giants, who were called Lemurians and Hyperboreans. However, the theory was criticized because, according to scientific facts, this simply could not be. Our planet does not have enough resources to feed such giants. And this is not the only rebuttal. If the growth of these creatures really reached enormous sizes, they would not be able to lift themselves, and with a sharp movement, the force of inertia would knock them down. In addition, their vessels would not withstand such a load, and the blood flow would break through their walls.

This is only a small part of the theory, but practical experience shows that each person chooses a version according to their worldview.

Numerous studies have shown that initially all embryos are female, and only during the period of hormonal changes some of themare transformed into males. Many scientists believe that this is due to changes in the male genotype, which entail violations in the Y chromosome. It is she who determines the male gender. According to these data, after some time the planet will be inhabited by female hermaphrodites. US experts support this theory, as they were able to prove that the female chromosome is much older than the male.

With the help of modern research, a huge number of facts have been discovered, but even they do not give a clear explanation of how and where a person appeared. Therefore, people have no choice but to choose the most appropriate theory for the origin of life, trusting their intuition.
