Do aliens really exist in the universe? Why haven t we met?

Aliens have always been speculated and conjectured by everyone, and I think that there is actually a possibility of aliens in the universe, and we have not met them, in fact, on the one hand, because the universe is too large, and on the other hand, it is also possible that the other party's technology is very powerful. <>

In fact, the universe is a very large space, I think in such a large space, there must be the possibility of giving birth to other life, we human beings through thousands of years of reproduction and development, step by step evolved into a human being, become a highly intelligent life form, but in other planets in the universe, I believe that there will definitely be such a reproduction process, there will definitely be some other life forms, they are also growing quietly, but this universe is too big, so it is difficult for us to meet them at all. We haven't even explored the planet, so we can't detect the existence of life. But it's possible that they are also speculating on the other side of the universe whether we exist or not. Because the universe is so large that it can accommodate a lot of human imagination, I don't think it's surprising that aliens exist.

And I think that if they are also living creatures, they must also have a certain amount of technology. Maybe compared to us, their technology will be more advanced, so they have been going around in circles with us, have been hiding their own signs of life, unable for us to detect, or it is possible that they are still in a very primitive stage, never came to the universe, so it is impossible for humans to meet them at all, this is very possible, these aliens may be much better at using technology than we are, they have become the most intelligent creatures in the universe. So we can't see these aliens, and it's a very normal thing.

However, it is meaningless to say that there is no evidence to support this view, so I hope that in the future, while we make further progress in science and technology, we can also really study aliens to see if they really exist, and I also hope that many human beings who have a reverie about aliens can be satisfied.

It should exist, because there are very many planets in the universe, and since there is an earth, there should be other planets with life. It may be that our technological development is not particularly good, and we have no way to explore some places, so we don't encounter them.

I think there are aliens in the universe, after all, there are many things that human civilization can't do, and we haven't met them because the level of science and technology can't reach the level of discovery of their existence.

Of course, there are aliens in the universe, and the reason why we have never met them is because we live on the earth and naturally cannot see aliens.

It is believed that there are aliens in the universe, but because our technology is not so developed, there is no way to cross the barriers of the universe, and there is no way to see aliens. So we can work hard to develop technology, such as interstar jumping technology, so that we can find aliens and communicate with alien civilizations.

The universe is very big, we only live in a corner of the universe, our life is very exciting, maybe there is another civilization far away light years away. So we can't be fooled by the current sky, maybe human beings just live in a four-dimensional space, and there are five-dimensional spaces outside of the four-dimensional space. So aliens should exist, but because our technology is not so developed, there is no way to see aliens.

For example, aliens will be stealth technology, even if they appear in front of our eyes, we are invisible, because of the technological gap, so the earth will also be rejected by interstellar civilization, and it will not be able to enter the era of alliances at all. Therefore, we can also work hard to develop science and technology, so that we can find alien civilizations as soon as possible, and we can also take a look at their technology and learn some advanced technology.

Maybe humans have already met aliens, but humans don't know that this thing is an alien civilization. We must know that the world is so big that there is no such thing as a civilization, and that there must be another civilization in this world. Now in many science fiction movies, there has been a future development, and many science fiction movies have also developed in the future, we can get the tip of the iceberg of the world from these science fiction and science fiction movies.

When looking at the world, we should be careful about the world, because we are only a small part of the world, and the world is very big. After all, the Earth is very small, and there are many planets beyond the Earth, but due to technological limitations, we cannot get close to these planets.

I don't know, these aliens are relatively little hidden, and they have not revealed any flaws, it is possible that there are no aliens in the world at all, and science and technology have not reached such a height at present.

I believe that I have always believed in the existence of aliens in the universe, because at present, human technology is limited, and we have not yet detected farther places, so we have not encountered them.

I don't think there are aliens, and the reason why humans have never met them may be because the technology is not advanced enough or there is no right time.

Not necessarily, the specifics are not very clear. Humans are not very clear about the activities of aliens, and have never really encountered aliens.

There are no aliens in the universe.

Since the exploration of extraterrestrial life by human beings, no footprints of extraterrestrial life have been found, let alone aliens, if they really exist, it will be a sensational event around the world, and it is obvious that whether everyone speculates or speculates, in fact, the result is the same "no evidence".

But science is all about evidence, and since there is no evidence of aliens found today, it must be "no", so from the perspective of existing science, it is no, and this does not need to be disputed.

To date, no extraterrestrial life has been discovered on other celestial bodies other than Earth, whether in lower forms or in intelligence. But I personally believe that there is a high probability that extraterrestrial life will exist, because the environment of the universe allows the existence of life on earth, and it is entirely possible to allow extraterrestrial life to exist, but human beings have not yet been able to detect it.

For the first time, human beings left their home planet, the farthest place on the earth was the moon, not only did there be no atmosphere on the moon, but after going up, they found that there was nothing on it, which can be described as lonely, empty and cold.

There are countless stars in the vast universe, and they may also be surrounded by planets, and astronomers have now discovered thousands of them. Some stars even have as many as eight planets, like the Sun. In this way, there may be stars in the universe with more planets than the Sun.

There are at least hundreds of billions of stars in the observable universe, and the number of planets may be even higher. There will always be planets that have an environment similar to Earth's, orbiting in the habitable zone of their star system, with liquid water on the surface, and they have the potential to give birth to life. Even on some planets with completely different environments, completely different forms of life have been born.

Astronomers speculate that life may exist on Titan's in the solar system, perhaps not on the basis of water, but on liquid methane. In addition, life on Earth is carbon-based, and extraterrestrial life may use other elements as the basis for organic matter, such as silicon and germanium, which are in the same group as carbon. It is important to emphasize that life conceived on different planets may have very different forms, and they are most likely not humanoid.

Because the universe is so big, the current astronomical observation technology is not enough for us to directly study the planets outside the solar system, and we have only explored a very small part of the universe, so we have not yet found extraterrestrial life. But with large-aperture astronomical telescopes joining the search, we could discover extraterrestrial life in the next few decades.

Whether there are aliens in the universe or not, we still don't know, with our current level of technology, we can't intuitively know whether aliens exist. But I believe that on some distant planet, there must be life forms like us.

Personally, I don't think it exists, and with the current technological development of human beings, it is impossible to detect the existence of aliens at all, so we can't arbitrarily guess.

I think there are still aliens, but I haven't seen them.

Are there really aliens in the universe?

Aliens exist! In the vast universe, among the countless galaxies and countless stars, it is impossible that only the earth has highly intelligent life!

And it is impossible for real alien UFOs to reach our earth, even if they have light-speed transportation, there is no such possibility.

Do some aliens have light-speed vehicles?

My point is, they have! Because, their technology may be advanced by tens of thousands of years or 100,000 years of our earth's technology!

Why don't they come to our earth?

It's because our earth is too small, so small, that their high technology can't be observed. Even if they did, they weren't interested in us, just like we looked at ants, or they weren't skilled enough to get to Earth with the difficulties they had, or the radio waves didn't reach Earth.

What are radio waves?

Radio waves refer to radios, and it takes at least 10,000 years, or even 100,000 years, for their radios to reach our earth, and we need 10,000 years or 100,000 years to answer the past. This is all to exclude encounters with strong gravitational objects. For example, "black holes".

What if they could live for thousands of years or carry on their ancestors? "Earth Time".

How many dangers are there on the way? The dangers we know are supernova explosions, black holes, and many more that we don't know about. Supernova explosions alone, black holes, these are even more impossible to reach.

Some alien technology is above us, how many dangers there are on the way, they know, and if they want to reach our earth, they can only overcome the dangers on the way...

Yes, since there are earthlings, there should be aliens, is there anything special about earthlings? Just like the earth is not the center of the universe, it is just an ordinary planet with life.

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.

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.
