During the development of humanity, many have had different beliefs about how it has evolved, and how life on earth began, with many with inclinations towards religion, as well as others who have scientific theories based on investigations, which in some have not been proven their veracity, as in others they have been discarded as inconclusive.
This issue has been of great controversy for many years, having groups of followers on both sides, because there are some who believe in the supernatural, as well as others who need everything to have an explanation and a why in order to make sense of it. .
All the beliefs of the theories of the origin of life, that are governed by religions are the oldest, since even civilizations such as the Egyptians, the Persians, the Romans, the Aztecs, and many more, were faithful followers of deities, who were responsible for granting them everything that the world could offer them, and even life itself, although there were and still today an endless number of religions can be observed, with totally different beliefs, all reach the same point in which a supernatural and all-powerful being was the one who gave beginning to the universe and the creation of life.
On the other hand, those who are inclined towards science, search among the events that have been archived of all the events that have transpired in the time that the planet has been alive, reaching different conclusions, presented by various scientists, who have reached to relate that it is very possible that life as we know it today, came from a totally different place from planet earth, and that it was there that it had the opportunity to develop and evolve.
Although many of these theories have been discarded because they have not been proven, and in turn demonstrated that certain events did not agree with the development of some species, scientists are still investigating how the existence of such precious life originated.
One of the theories of life that caused the most controversy was that of evolution, which explained that human beings come from primates, which means that people with religious beliefs and the same institutions were upset, because being According to them, human was created in the image of the lord, which they took as an insult to try to say that they came from an animal.
The most relevant theories of the origin of life in the entire history of humanity can be divided into two types, as we have seen previously, those of religious beliefs and those of science, which have very different ways of thinking, and they themselves they break down into various types of theories.
Theories according to scientific beliefs
Among the thoughts of great scientists, various theories of how life was created have been determined, among which the most relevant ones will be mentioned:
Big bang theory
This theory is the most relevant in the scientific field in which important figures such as Albert Einstein have been involved, who gave great contributions with his theory of relativity.
This consists in that approximately 13.800 million years ago, all matter was tightly united in one place, which was very small, when suddenly for some reason, it heated up in such a way that it exploded, spreading over a long territory creating clouds of sub-particles and atoms, that later when cooling were forming the celestial bodies, planets and others.
This theory says that the universe is constantly expanding, So every minute that passes, it could be said that there is the possibility of creating a new life, since it is made up of atoms and molecules that float in the entire universe.
The new origin theory
This theory was created by a scientist at Heidelberg University in Germany, whose thoughts say that the creation of life was not thanks to a great explosion, as expressed by the Big Bang theory, but that it took place after a long period of absolute freezing suffered by the entire universe, to then take a temperature suitable for the origin of life.
Theory of spontaneous generation
It is a very old belief, that even civilizations like the Mayans believed, which says that every living being comes from some organic or inorganic material, and even from a mixture of both, in which it was thought that flies came from manure or from garbage, mice came from paper or cardboard, and ducks from some fruits.
This theory was supported by several famous people, such as Aristotle, although later in the seventeenth century the biogenesis theory which said that living beings come only from other living beings, but it was not until the nineteenth century that this theory of the origin of life was discarded.
Panspermia theory
This is a theory that has the basis of its beliefs, in that life on earth is not native to itself, but is extraterrestrial life, which was transported by meteorites and comets throughout space until reaching the surface. land.
It was called the controversial theory, Because he said that these organisms were able to withstand the hostile temperatures of the vacuum of the universe, as well as the intense heat that any body presents when penetrating with the first layer of the earth.
This theory was discarded because it did not have sufficient evidence that microorganisms with the characteristics described above existed.
Followers of this theory are divided into two types, those who claim that the microorganisms were intentionally directed to the ground, and those who say that it was naturally.
- Directed panspermia ensures that intelligent beings from other planets sent matter capable of forming life in meteorites with the intention of verifying if the territory was suitable for life.
- And the natural one is based on simple chance, that is to say, that by luck or by destiny the microorganisms arrived that had the capacity to create life as it is known today.
Theory according to religious beliefs
Among the different religions that can be observed around the world, there are different beliefs, since they are very diverse, but among the best known is the theory of creationism, which can be observed in many different cases such as creation according to the Mayans.
Creationism
This is based on the Genesis chapter described in the Bible, in which it says that the earth was created in 7 days by a divided entity called God, who on the first day of his work to create existence, dedicated himself to the heavens and the seas that would cover the entire earth, and later in the second to dedicate to the light that provided clarity, and to the darkness.
The first signs of life that were seen in this theory of the origin of life, was in the third step that God took, which was the creation of plants, and then on the fourth day to create the sun that would only be in the day and the moon that would light up the dark nights.
Fish and birds would have their time, already on the fifth day, which would inhabit the heavens and seas created on the first day, and thus on the sixth day would create the beings that would inhabit the earth, among which would be several species, like mammals, reptiles, amphibians and others, creating man together with them.
Although I only created a man, whose name was Adam, after seeing the other animals God understood that he would need company, so he put him to sleep and took some ribs from him, with which he formed a woman, named Eva, who were the ones who inhabited the divine land, known as paradise.
As well as this, there are theories of creationism of ancient cultures such as the Mayas, the Egyptians, the Greeks, among many others, who have a mythology with various gods, which are commonly given to the forces of nature, to which each was responsible for the creation in a certain respect.
Although scientific and religious beliefs do not agree, it has been determined that scientists have relied on many mythologies from various civilizations to support their hypotheses, serving as a guide to make them.
As well as a great controversy, regarding the teaching of children in schools, because in the last years of the XNUMXth century, religion was very strong, and the high command of these, said that some theories were inappropriate to be taught to future generations.
At present, these theories of the origin of life are very important for biological research, and are fundamental bases for the study of the human being.
