The origin of life - several options

One of the most important issues for many years occupying the minds of scientists and ordinary people is the question of the emergence and development of the diversity of life forms on our planet.

At the moment, theories of the origin of life on Earth can be classified into one of 5 large groups:

1. Creationism.
2. Spontaneous life.
3. Hypothesis of stationary state.
4. Panspermia.
5. Evolution theory.

Each of the concepts in its own way is interesting and unusual, so it is necessary to get acquainted with them in more detail, because the origin of life is a question to which every thinking person wants to know the answer.

Creationism includes the traditional beliefs that life was created by a certain higher being - God. According to this version, the soul is the proof that all living things on the Earth were created by the higher mind, whatever it is called. This hypothesis originated in very ancient times, even before the founding of world religions, but science still denies the viability of this theory of the origin of life, since the existence of a soul in humans is unprovable, and this is the main argument of creationists' apologists.

The hypothesis of spontaneous generation of life appeared in the East and was supported by many famous philosophers and thinkers of Ancient Greece and Rome. According to this version, life can under certain conditions arise in inorganic substances and inanimate objects. For example, larvae of flies may form in rotting meat, and tadpoles in wet mud. Such an approach also does not withstand any criticism from the scientific community.

The hypothesis of a stationary state seems to have appeared together with the appearance of people, since it says that life did not emerge - it always existed approximately in the state in which it is now.

This theory is mainly supported by the studies of paleontologists, who find ever-increasing evidence of the existence of life on Earth. True, strictly speaking, this hypothesis is somewhat distinguished from this classification, since such a question as the origin of life, it does not affect at all.

The hypothesis of panspermia is one of the most interesting and controversial. According to this concept, life on Earth was born as a result of the fact that, for example, microorganisms were somehow brought onto the planet. In particular, the studies of a scientist who studied meteorites Efremovka and Murchisonsky showed the presence of fossil remains of microorganisms in their substance. However, there is no evidence of these studies.

The paleocontact theory, which says that the factor that triggered the origin of life and its development, was the visit of the Earth by aliens who brought microorganisms to the planet or even specially populated it. This hypothesis is becoming more widespread in the world.

Finally, one of the most popular scientific theories explaining the origin of life is the hypothesis of the evolutionary appearance and development of the living on the planet. This process is still ongoing.

These are the main hypotheses trying to explain the origin of life and its diversity. None of them can not yet be unequivocally accepted or rejected. Who knows, maybe in the future people will still solve this riddle?
