Human civilization has gone extinct several times, and human beings have gone extinct several times

Legend has it that prehistoric civilizations became extinct 5 times for various reasons. The details are as follows:

1. Two billion years ago, nuclear energy was used at the birth of a civilization, and it was finally destroyed in a nuclear war. This may explain why the phenomenon of nuclear reactors in South Africa's uranium ore was established two billion years ago.

2. 500 million years ago, sub-civilizations were born, and they were able to build flying machines, go into space, and finally be destroyed by aliens. This may explain the statement that the moon is hollow and is monitoring the earth.

3. Sixty-five million years ago, three civilizations were born, and the remnants of the previous civilization could be used, and the number of births flew out small, and finally they were destroyed by an asteroid impact. This may explain the extinction of dinosaurs and large numbers of creatures.

4. Fifteen million years ago, the fourth civilization was born, and it did not use nuclear energy, but it could observe space from a distance and build flying machines, which was about the same level as our civilization 50 years ago. It was finally destroyed in the Ice Age.

5. Seven million years ago, the fifth civilization was born, which could use a large amount of nuclear energy, slightly higher than modern civilization, and was destroyed by a global flood.

So far, existing studies have not been able to confirm how many extinctions humans have experienced, and there are five mass extinctions that can be confirmed. The five mass extinctions are, in chronological order: 1. Ordovician-Silurian extinctions.

2. Extinction in the late Devonian. III. Permian-Triassic extinction. 4. Triassic-Jurassic extinction.

5. Cretaceous-Tertiary extinction.

Paleontologists believe that the first mass extinction was caused by a cooling global climate. The second extinction, the late Devonian, was caused by severe hypoxia on the seafloor, and in the second extinction, terrestrial organisms were not significantly affected.

Studies have shown that the impact of the third mass extinction on plants is not obvious, and many new plant groups have emerged after the third extinction. The cause of the fourth mass extinction has not yet been definitively determined.

The fifth mass extinction is also known as the "last age of dinosaurs", after this extinction, no living dinosaurs have been found on the earth, and the cause of the fifth extinction is inconclusive, and it is speculated that it was caused by meteorites hitting the earth.

There have been four exterminations, and now this is the fifth.

Ask a question [than heart].

Second mass extinction: about 36.5 billion years ago, in the late Devonian period, marine life was devastated and amphibians emerged.

The third mass extinction: about 250 million years ago, at the end of the Permian, the largest and most severe in the history of the Earth, the extinction of amphibians and mammal-like reptiles, and the emergence of dinosaurs.

The fourth occurred 18.5 billion years ago, when 80 reptiles became extinct.

The fifth occurred 65 million years ago in the Cretaceous period, when the dinosaurs went extinct and mammals flourished.

We are facing the sixth mass extinction, which is also the most dangerous due to the acceleration of human industrialization and the extinction crisis that has swept through the entire ecosystem.

Four times in total, and now the fifth. The first was the Gendaya civilization, where humans were one meter tall, men had third eyes, and women's wombs had the ability to communicate with the gods, and the civilization was destroyed on the continent and sank; The second is the Mesopotasian civilization, where the third eye of human beings began to disappear, and they were particularly fond of food, and developed various food experts, which were destroyed by the conversion of the earth's magnetic field; The third is the Mulia civilization, where humans used the huge energy generated by plants when they germinated to invent plant-capable machinery, which was destroyed on the continent and sank; The fourth is the Atlantean civilization, they are all colonists of Orion, who have the power of light, because of the destruction of nuclear war. We are now the fifth civilization.

Humanity has gone extinct four times, and now it's the fifth.
