In Darwin's theory of evolution, we can know that all living things on earth evolve with the change of environment. Then, how did the dinosaurs that ruled for more than 65.438+0.5 billion years perish? Although we don't have conclusive evidence to prove the cause of the extinction of dinosaurs, the general public opinion all over the world is that asteroids hit the earth. After the asteroid hit the earth, the earth's environment changed greatly, and all the dinosaurs died because they could not adapt to the environment.

It can be seen that human beings are still very lucky. Because mankind has never encountered a global disaster, and there is no very powerful opponent. If dinosaurs were not extinct, it is estimated that the earth would still be ruled by dinosaurs. Now that mankind has passed the fragile period, the current technology is enough for us to face various crises.

According to cosmic observation, both the sun and the earth in the solar system are in the middle stage, and this situation will remain for more than one billion years. Therefore, the biggest threat from the universe is still very far away for us. So, will there be another mass extinction event on earth? The answer is yes. Because according to statistics, the earth will experience a mass extinction event every 45 million years, basically because of the impact of foreign asteroids.

If mankind encounters a catastrophe, can it survive? The answer is that humans will not become extinct like dinosaurs. First of all, such a huge disaster is still far away for mankind. If calculated according to the cycle of 45 million years, human beings still have thousands of years, so don't worry at all. What's more, the current level of human science and technology has made rapid progress.

You know, it's only a hundred years since humans realized the Big Bang. Now we can explore the universe and plan to land on Mars. The dinosaur era lasted for hundreds of millions of years, but no advanced civilization evolved. It can be said that human beings are unique on the earth. Even if human beings face various crises in the future, according to the development level of human science and technology, human beings at that time can already complete interstellar migration, especially the weapon system will become very powerful.

From this perspective, as long as mankind does not perish, such as wantonly destroying the environment and launching a global war, nothing can stop human development. Therefore, we don't have to worry about the fate of mankind at all. What happened during the dinosaur period will never happen to humans. In the vast universe, the earth is definitely not the destination of human beings. I believe that one day we will fly out of the solar system and explore this vast space.
