Is there an alien in the universe 20

In the 18 billion planetary systems of the Milky Way, if 1 percent of the galaxies have the possibility of life, then the probability is 100 million, if there is 1 percent of the creatures in these 100 million planetary systems, then the probability is 1.8 million, and if 1 percent of the 1.8 million planetary systems are intelligent creatures, then the probability is 10,000. If you count all the galaxies out there, the probability is scary. Therefore, the idea that "there is life only on Earth in the universe" is naïve and ridiculous.

dear,please believe me!

You can think about how small the earth is ==!

Are there any aliens in the universe?

Are there any aliens in the universe? Star Awareness Project

Are there any aliens? According to the Fermi paradox proposed by the famous Nobel laureate Fermi, if there are aliens, then they may have come to Earth and exist somewhere, but they just didn't communicate with us, maybe our technology is too backward to detect them; Or that there is no other civilization in the universe.

The answer is yes, there must be.

First, when you say the world, you mean the whole universe. Actually, there is a pattern to this question, and if you are targeting an American, you are a foreigner. Then you are an alien to intelligent life beyond Earth.

Alien is actually a generic term. Meaning higher intelligent life forms beyond Earth. It's not that you have to look like a human to be an alien, different environments create different life forms.

I remember there was a report that some geologists had found frogs, duckweeds and beetles, and fish and shrimp in a hole in a sulfur-rich area. Their bodies are all yellow. A simple food chain is formed.

But they are very different from the same kind of animals and plants in other places on the planet, the plant is duckweed, which absorbs the dead fish and shrimp and their feces and sulfur, and the fish and shrimp also eat these things, and the frogs eat the beetles, and the beetles eat the sulfur and duckweed! They all breathe sulphur gas, and none of them can absorb oxygen. Once out of that cave, they will die (suffocate) or be poisoned.

That is, the air outside is toxic to them. But the gases they absorb are toxic to us. Such a phenomenon will occur on the same earth, so.

I think there will be life on other planets that have the sun, water and the right temperature, and where there is a lot of organic transformation. You don't have to breathe air, but you have to have water and sunlight (or thermal substances that can replace sunlight) and the universe has been formed for so many billions of years, how many years has it been since civilization appeared on Earth? Now that they are able to fly out of the earth, it is not impossible that there will be life forms with more advanced technological civilizations.

It is also possible that countless civilizations have been destroyed!! So there is a certain !! when there are aliens

Second, some scientists have proved that there was a mysterious tribe in Africa in ancient times, and the civilization of such tribes was very advanced compared to modern humans. But they do not interact with outside humans, and scientists suspect that they are aliens who were killed on Earth. However, the earth's scientific and technological resources are not enough to maintain and maintain the aircraft, so they can only settle on the earth.

But they seem to be abiding by a law that they cannot influence the technological development of the earth (that is, the backward planet). They never communicated with earthlings in terms of knowledge and life, and finally found dead from an infectious disease on their site. An entire race died from the disease!!

Extraterrestrial creatures do.

Extraterrestrial intelligent life should also be possible.

Not necessarily, with aliens.

Of course, if you say that aliens are just a kind of advanced intelligent creatures and not the same as humans in DNA, then there must be.

Life in the universe should be extensive.

Because according to the survey, it is possible that there was life on Mars.

Hehe, this question is difficult, many people have always claimed to have seen aliens every year, but almost no one can come up with sufficient evidence. At the same time, there are many people who are deliberately looking for aliens, but so far no one has ever said that they have succeeded. I believe that the universe is boundless, and there will always be life other than human beings, although it is not necessarily highly intelligent.

Of course, there are also intelligent beings that are higher than humans. Well, the landlord's question is still inconclusive, maybe the answer will come out automatically in the future.

No, the universe is composed of various substances, intertwined with each other, life is only a form of matter, and it must be produced under the same conditions, and there are no two identical and identical earth environments in the universe to produce life. There is only one cause process for the production of an effect, and the so-called "aliens" we go to find are like going out to find ourselves.

It may not be, I don't know yet, but I'll know when science and technology develop.

Yes Speculation: From experience (there are two sides to everything), it can be said that the universe does not allow life to exist in just one corner of it.

The heroine of the movie "Chrono Contact" has a sentence: If the universe only has life on our earth, wouldn't it be too wasteful

I don't think there's anything on Mars.

I also agree that there are aliens, the universe should be infinite from our current understanding, and there must be planets suitable for life in such a large universe!

Theoretically. I don't know yet.

Now scientists have twice discovered that there are living beings, and there may be aliens in the universe.

Sometimes it's just that it's just too far away for living creatures to boast of beyond that distance, so they haven't explored extraterrestrial creatures yet...

Oh, if it's theoretical, I think there should be, although it hasn't been scientifically proven yet, hehe, if you talk about it, it's also possible that it has been scientifically confirmed, but it's blocked by the Pentagon, haha, of course, it's an imagination, I think the universe is so big, there must be other life, but we haven't found it.

Definitely we are aliens.

Can there be no universe that big?

Is there really any other life beyond Earth?

I've always believed that there are aliens. I used to read books on this and was so scared that I didn't dare to sleep.
