The end of life is because it has perished
-
Soon after the disappearance of humans, cities will be covered with vegetation.
Houses will gradually collapse.
A single lightning bolt can cause a fire in an alluring city.
Water pipes will be weathered and rain will be rained and so on, cities will be covered with water around 5,000 years ago, nuclear warhead shells will be corroded, nuclear materials leak 20,000 years later, nuclear winter will lead to the arrival of a new ice age, urban buildings will be covered by glaciers 1 billion years later, the earth will become hotter because the sun is getting bigger, because the sun is constantly expanding.
During this time, the species on Earth will complete their evolution and adapt to the hot Earth.
If a highly intelligent creature evolves, it will rebuild the city during this time, but will eventually destroy or leave the Earth.
Five billion years later, the Sun's constant expansion has engulfed Mercury and Venus, and the Earth will become a sea of fire until it is swallowed up by the Sun.
Trillions of years later, the Earth ceases to exist. Maybe some dot waves can float in the universe. These signals may be received by aliens or highly intelligent beings who have escaped from Earth.

What will become of the Earth when humans disappear? The answer given by the scientist is sad!

As we humans continue to grow and develop, how can such a large number of human beings come to a consensus that they can cooperate with each other without large-scale infighting? In some other species on the earth, their behavior is basically guided by genes, that is, they are innately formed, which determines the composition of their social members.
But we humans are different, human beings live in an orderly way by relying on an imagination that rules the earth, and it is this imagination that helps us to create a social order, and even a huge global domination.
Innate genes are only a part, but the bigger is the acquired creation of this kind of rules, that is, what we usually call morality, law and even some conventional customs, in human society a lot of division of labor is relatively clear, but these are through a certain learning can be obtained, not innate genetic determination, human beings can obtain some new skills through learning.
It's like the difference between us humans living in the Arctic and polar bears.
Polar bears can only rely on innate genetic behaviors to slowly adapt to changes in the earth, and if they fail to adapt, this natural environment will be directly extinct. And we humans are in the Arctic region, although the temperature environment changes.
But we can use the outside world, such as building igloos and wearing some thicker fur coats, so that we can adapt well to the changes in the natural environment, and this ability to adapt to changes constantly and quickly, which also helps us humans to establish orderly rule on a global scale, and gradually become the supreme ruler, to the top of the food chain, which plays a decisive role.

That's right. The planet we live on is called Earth, which is one of the eight planets in the solar system.
Mars, Saturn, Venus are all planets in the solar system.
The solar system and the eight planets.
Mars is a terrestrial planet and is the only planet in the solar system where life is possible.
Venus is the brightest celestial body in the sky, except for the Moon. It is also the planet with the highest surface temperature in the solar system, with more than 400 degrees Celsius.
Saturn belongs to the gaseous planets. It has a beautiful aura. It is the second largest planet in the solar system in terms of volume and mass, after Jupiter.
The earth is the only planet on which human beings depend, so we must cherish it. We will strive to protect the ecological environment of the earth.

There should be.
It is possible for extraterrestrials outside of Earth or for earthlings to become aliens on other stars.
Because the universe is so big, it is impossible for there to be life on only the earth, there must be life on other planets, but we have not yet discovered it.
And the earthlings have already landed on the moon, and at that time these astronauts have become aliens on the moon, so there are aliens in the universe.
It is also certain that there were humans when they landed on other stars, because at this time these people became aliens on this star.
And the question of whether there are aliens outside the earth in the universe is still unanswered.
But what is certain is that there is no conclusive evidence that aliens have ever visited Earth.
It is not uncommon for some people to refer to natural phenomena that cannot be explained by science today as extraterrestrial visits (UFOs).
And a lot of the time what they see is actually an artificial aerial vehicle.
There are also some people who say that the ancient civilization of mankind is an alien civilization, and attribute everything that cannot be explained now to the masterpiece of aliens, which is an insult to mankind itself!
In fact, human creativity is very strong, and what we can't do now doesn't mean that ancient humans can't do it.
Don't say anything is alien.
UFOs, on the other hand, refer to unidentified flying objects, which refer to all non-man-made flying objects.
UFOs must be there, and there are many things that humans can't explain. But whether it is related to aliens is unknown.
The earth is the home we live on, and it is also the most special planet in the actual exploration scope of the universe at present, because of the existence of living organisms, of course, there are advanced civilization technology, which has many key factors, such as the temperature of the sun, and human beings will be very curious if the earth is separated from the sunWill humanity continue to survive? I don't think it will work, it will be a huge disaster for the planet. >>>More
For the universe, the earth we live on is just a very small existence, so to tell everyone, the earth we live in belongs to the Milky Way, and the Milky Way is only a medium galaxy in the universeThere are at least billions of such galaxies, so the earth is normal, and the special thing is that only life has been found on the earth, and people will wonder if there is only life on the earth, what is the meaning of the existence of the universe after the destruction of the earth? The universe itself is of great significance, with countless opportunities for development, and it is not as simple as we think. >>>More
A: No.
Humanity will not become extinct because of the spread of the novel coronavirus. Throughout the history of human development, it is a history of constant struggle against various diseases. Smallpox, a virulent infectious disease, has been basically eradicated, and plague, cholera, and other virulent infectious diseases have also been effectively controlled. >>>More
The earth is bound to perish.
It is unpredictable how it will perish. >>>More
No, because humans have a weapon --- war. But over-reliance on technology is obviously irrational, so the exact conclusion is that humanity will not be destroyed by technology, but most people will be destroyed by technology.
