Let me say a few words, this is a question that many people ask, but all of them are not exact.
Personally, I think that there are absolutely aliens, because the earth cannot be the only planet in the universe suitable for biological survival, there are about 200 billion stars in our galaxy, and a star represents a galaxy, for example, in our solar system, the sun is a star. There are no fewer than 20 million planets in the Milky Way, which means that there is a 1 in 10,000 chance that planets in stellar orbits will be similar to the Earth. There are many opportunities for aliens.
But I don't think there are aliens on Earth at the moment, mainly because the distance is too far, imagine that the closest star to our solar system is the Centaur galaxy, the speed of light is still four years, and now our spacecraft is only 80,000 kilometers per hour at the earliest. Communication is transmitted by radio, which is the speed of light, which is quite slow. It takes 10,000 light-years to explore the Milky Way, but what about the Milky Way in the universe?
Tip of the iceberg!!!
-
There should be! Because the universe is so big, the planet suitable for highly intelligent animals like humans should not be the only planet!
-
I only believe in science, I think four or six points, forty percent have, sixty percent not, let science prove it
-
Just like aliens don't believe in the existence of humans, but humans exist!
-
Do aliens really exist in the world?
-
If you believe it, you can't believe it!
-
Are there aliens in this world?
-
Aliens invade Earth and end up falling in love with a woman.

Reports of aliens are often reported in the newspapers, many people claim to have seen flying saucers, and even seen aliens, and they have also taken all kinds of ** about flying saucers, but the exact evidence is not yet available.
Howard Smith, an astrophysicist at Harvard University, has a negative attitude towards people's fervent desire to find "partners" in the universe. He said that although there are thousands of in-situ planets with a similar volume to Earth, their own climate and other conditions are very likely to be very unsuitable for the existence of life forms such as ET in the movie image.
Russian astronomer Professor Finkelstein believes that "the emergence of life is an inevitable product of the development of complex atoms, life must exist on other planets, and mankind will discover them in the next 20 years." When asked about what the aliens look like, Finkelstein said they may resemble humans, with two hands, two legs and a head. He said
Aliens may have different skin colors, but humans also have skin color differences. ”

There are aliens in the universe, but we haven't discovered or confirmed them yet.
First, in the vast universe, we have only discovered one-half of it, and there is still a large part of it that has not been discovered, so it cannot be said that there must be none.
Second, like the earth millions of years ago, it was not the same, there was no living thing, and it was not after a long time that there were living things; So, before that, it cannot be said that there was no one; After this, it is not certain that there will be no more.
Third, extraterrestrial beings don't have to be the same as us humans, and their needs don't have to be the same. For example, a long, long time ago, not long before a human being, someone fell into the water and drowned, and he would say, "There can be no life in the water."
But it wasn't long before fish were discovered. Now, none of us will be surprised that there are creatures in the water.
The top 10 extraterrestrial "paradises" with the potential for life include the star Pegasus 51, which was first discovered outside the solar system by Swiss scientists in 1995. There is a Jupiter-like planet orbiting the star nearby, and life is likely to be present on it. In addition to this, the list also includes the star numbered "Scorpio No. 18" in the constellation Scorpio.
The celestial system in which the star is located is very similar to the solar system; There is also the "Alfa Sagittarius B", one of the closest stars to the solar system; There is also a three-star system in the southern hemisphere sky, which is only light-years away, a cold and faint star, a brown dwarf, orbiting another brown dwarf, and together they orbit a regular star, which resembles the sun, with a luminosity of one-tenth of the sun, and there are conditions for life in its vicinity.

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.

Even if the world's most famous scientist says that there are aliens, it is not necessarily true or false. Because so far, people have found planets with no oxygen, no water, extremely high or very low temperatures, oxygen, water, temperatures of -30 degrees to 150 degrees are necessary for life to exist, but none of these planets have such conditions. If these conditions alone are relied upon, the existence of extraterrestrials in the universe has been denied.
However, scientists often receive some radio signals in radio telescopes, which are not like rays emitted by stars in the universe, but have certain laws, as if they are emitted by intelligent beings, but not really no one knows. The universe is so big, maybe there are aliens.
-
I think there is, although I haven't seen it with my own eyes, but the universe is so big that anything can exist.
-
It feels like this thing is discussing whether there are ghosts in the world, that is, far and near, and ethereal! Generally speaking, there seems to be no definite answer to this question, and many scientists around the world are constantly working on it. But my personal opinion:
Aliens are supposed to exist! It's just that it hasn't been discovered head-on by our so-called scientists, at zero distance. Maybe their life forms are unexpected by us, maybe they are so far away from us, but the possibility of existence is greater than the non-existence.
After all, the universe is so big that it is beyond the ability of human beings to explore and perceive. Their existence cannot be denied because we do not have a positive discovery. It should be right and objective to believe in their existence.
-
I think there should be, because I've read a lot about aliens in books, and since it's written, there must be any.
-
Not sure, but that doesn't mean no.
-
I believe there is, but I haven't seen it.
-
Yes, it depends on your definition of aliens.
-
You think there is, you think there is, you think there is none
-
Yes! The universe is huge, there are n planets!
n solar systems!
How not?
-
There are aliens, and I'm using the time of the aliens to know that they exist.
-
Yes, however, it doesn't necessarily come to Earth.
The universe is so big, and any planet can have it.
There are definitely other planets that have developed life.
-
Of course, since there are human beings living on such a planet, there will naturally be similar planets
-
Leave behind the preconceived notions and learn about the 8 possible extraterrestrial life forms in the universe.
-
Not sure! Haven't seen it!

Yes, it is possible for people from other than the earth to accompany the stars or for the 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 are no aliens in the world.
I think aliens exist:
Outside in the narrow sense. The height of the star is higher than that of a star other than Earth. >>>More
Aliens must have been to Earth.
UFOs must have been there for a while. >>>More

Say the Earth, the Solar System, the Milky Way, what Orion, Ursa Major, this and that, Libra, Aquarius, how vast are these ranges, so vast that you have fresh water on Earth, you have life on Earth, people don't have it, it's unlikely.
