There are aliens in the world, are they fake? Has anyone really seen it?

There are no aliens in the world, but there may be alien creatures in the universe, but they don't have to be humanoids! Maybe we can see it in the future when the technology is more developed! Then it's up to you to see if you live to that day!

Drake's formula.

Equation 1 is: n=ng fp ne fl fi fc fl

Meaning: The number of civilizations in the galaxy that may communicate with us = the number of stars in the galaxy The proportion of stars with planets The number of terrestrial planets in each planetary system The proportion of habitable planets with life evolution The probability of evolving sapient beings The probability of sapient life being able to communicate The proportion of the duration of technological civilization in the life cycle of the planet.

Where: n represents the number of civilizations within the galaxy that may communicate with us.

ng The number of stars in the Milky Way.

FP stars have planetary proportions.

ne Number of terrestrial planets in each planetary system.

FL has a proportion of habitable planets where life evolves.

The probability that FI will evolve into highly intelligent creatures.

The probability that FC is highly intelligent and that life is able to communicate.

FL Tech Civilization Duration as a Percentage of a Planet's Life Cycle.

Equation 2 is: n=r* fp ne fl fi fc l

The difference between Equation 2 and Equation 1 is that R* replaces NG and L replaces FL.

r* is the average rate at which stars are formed in the Milky Way, and l is the lifetime of technological civilizations.

Inference for the equivalence of two expressions.

If the stars of the Milky Way are in a stable state (consistent with modern observations), then r* is equal to the number of stars in the Milky Way (ng) divided by the average lifetime of stars (ls).

r* l is equal to (ng ls)l=ng(l ls). Since (l ls) is essentially the same as fl, the two expressions are equivalent.

The Drake equation, while simple, is unsolvable. The biggest uncertainty term in this equation is the "time of existence of technological civilization (l)" because this term depends on the technological civilization itself, some of which are known. Since l is the largest uncertainty, in Project Cyclops, the equation can be reduced to n=l.

No matter how conservative we are, there must be extraterrestrial intelligent life in the universe. Even if all the terms of the Drake equation were to be the lowest value, assuming that technological civilization would only last for 100 years. Then the galaxy has the n= of technological civilization, which means that only humans exist in the galaxy.

But! Billions of galaxies have been discovered, and there are far more galaxies in the universe than that. Then the number of scientific and technological civilizations in the universe is also hundreds of millions, but this average distance is not 200 light-years but 2 million light-years.

It's hard to say, I personally think that there are still extraterrestrial creatures, since there are so many weeks, there are creatures on the earth, what reason is there for some other planets not to have it.

Even if it's true, someone has ever seen it tell you, do you believe it or not?

Yes, it is possible for aliens other than Earth or 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.

There have always been reveries about aliens in ancient and modern times, but now human beings have not been able to actually detect the existence of aliens, although many people have always claimed to have witnessed aliens visiting the earth and even having contact with themselves.

Aliens invade Earth and end up falling in love with a woman.

The reality is that no one has ever seen an alien until now, and although there are many bizarre events and suspicious physical evidence that confirm that there may be aliens, it is still impossible to confirm the existence of aliens, and speculation is still being debated.

Probably not on Earth. But the universe is very vast ...

Do aliens really exist in the world?

Are there aliens in this world?

I think that the universe is very large, and there should be many planets in this vast universe that have the same conditions as the earth that are adapted to the living conditions of organisms, so there should be many planets with extraterrestrial life. However, I think that although there is a chance of extraterrestrial life, it does not mean that there is advanced intelligent life. Because although the evolution of living things is from low to high, it is not from low to intelligent.

The direction of biological evolution is not towards the development of higher intelligent organisms. In other words, it is not inevitable that there will be humans on Earth. Nor is living things moving in the direction of high intelligence.

Some organisms have existed on this earth for hundreds of millions of years, but they have not yet reached the point of intelligence. Dolphins and whales used to be mammals, but now they have not evolved brains, they have evolved more developed sonar systems. And the human brain has evolved because of the selection of conditions, so that the human brain has developed.

The dolphins' sonar systems are also due to the selection of conditions, and the conditions in which they operate require them to have a sonar system.

Therefore, there should be life in the universe. However, the opportunity for intelligent beings to emerge is very rare. The earth is only 4.5 billion years old and has intelligent life.

The universe cannot have only life on Earth for 20 billion years.

So I think there is!

No one has ever seen aliens, and most of the people who say they have seen aliens do so to make money by becoming famous. Just like the South China Tiger.

I believe there is, after all, the universe is so big, it's not surprising that there are aliens.

Aliens invade Earth and end up falling in love with a woman.

Are there aliens in this world?

Are there really aliens in the world?

The universe is vast, and it cannot be denied that there is intelligent life like humans in outer space, but whether these aliens know that there are earthlings in the universe is to be seen, maybe they are also struggling to find extraterrestrial life and can't see it, although in recent years, there have always been extraterrestrial incidents, but there are always all kinds of loopholes, assuming that there are really aliens visiting the earth, why don't they openly meet with the earthlings, but as the outside world says cowering, is it afraid of human beings? Since they have flying saucers, which humans can't build for a while, it means that their technology is much higher than that of humans, and it is easy to deal with humans, so why be afraid. Therefore, I personally think:

For aliens it is better to believe that it exists, not to believe that it does not, but for"ufo'Should we treat the incident calmly, or hope that human beings will discover extraterrestrial life one day sooner, and also look forward to the day when real aliens will visit the earth.
