Why can life on Earth last for billions of years?

Because life on Earth has the ability to evolve and can evolve according to the environment, it can last for billions of years.

Because the Earth's environment can provide a place for life to thrive, it can last for billions of years.

Scientists believe that it may be that there are too many disasters in the universe, and even if some planets become life planets, they have ended in various disasters later, and have not finally grown into civilized planets, but the earth has the protection of other galaxies.

About 3.5 billion years have passed since the beginning of life on Earth.

The first life on Earth was born in the primordial oceans about 3.5 billion years agoCyanobacteria, cyanobacteria are also calledCyanobacteria, blue-green algae, is a single-celled organism as wellProkaryotes

Modern archaeology proves that there were living things on the earth between 200,000 and 100,000 years ago, and they originated in Africa.

In the field of paleoanthropology, there are professional expressions of evolutionary stages such as Australopithecus, ape-man, homo sapiens, homo erectus, homo sapiens and modern man, which have been widely recognized by the academic community.

This is to say that the conditions for the conception and evolution of life itself are extremely harsh, and it is precisely because of this that the original conditions on the earth allow life to be conceivedFor us, after hundreds of millions of years, if the earth's environment changes, then this time will also lead to the inability of life to conceive and survive, and will also lead to the extinction of life, so we can think about the problem from the following aspects. <>

1. It is very fragile for life itself, and it is precisely because of this that the dependence on external conditions is also very harsh, and if the conditions do not allow life, it cannot survive. In fact, it has to be said that life itself is very fragile, and it is precisely because of this that the dependence on external conditions is also very strong, and it is precisely because of this that if the external conditions do not allow it, then it is difficult for life to escape from prison and survive, so whether there is life depends on the specific environment of the earth after 100 million years. <>

2. It is not easy for us to produce life, but it is easy for life to die, so the earth may also easily destroy life. In fact, we have to say that we will find that life from birth to death itself is a cycle of process, and in this process, the energy of any matter is constantly transformed, and for us the death and disappearance of life itself is a reasonable thing, and for the earth will not change much, so some disasters may also wipe out life on the earth. <>

3. For us, whether there will be no life on the earth at all depends on many reasons, the most important is whether the earth's environment can provide conditions to support. In fact, it has to be said that whether there will be any life completely disappeared on the earth also depends on many reasons, the most important thing is whether life can live on the earth, and whether the earth can meet the minimum conditions for the survival of life, which is the fundamental condition for whether the earth can be completely free of life after hundreds of millions of years.

In fact, I have to say that life itself is very fragile, and it is precisely because of this that it is very easy to lose life, and after hundreds of millions of years, if there is a catastrophe on the earth, it will also lead to changes in the earth's environment, so life will not be able to survive on the ground, and the earth will be reduced to a desolate planet without any life.

Yes. Because after hundreds of millions of years, the sun's lifespan will be exhausted, and when the time comes, it will swallow the earth, so there will be no life on the earth at all.

With enough technology and depleted resources, human beings will definitely go out of the galaxy and find a new home, but only with air, water, light and heat, there will definitely be life.
