It s been almost 1 century, why haven t aliens been found yet?

The universe is too wide. From ancient times to the present, the alien theory is only hypothetical, and it is possible that there is no other life in the universe at all. So, it's normal that no aliens are found.

Because the conditions for the birth of life are too harsh, there may be no aliens, so no aliens have been found.

Since the beginning of the last century, humanity has begun to find its mate in the universe, which proves that humanity is not alone in the cosmic environment. In order to be able to find aliens, humans have put in a lot of effort. The results were unsatisfactory.

Because for more than a century, mankind has not found any evidence of the existence of foreign civilizations.

Are there really aliens? It's still a mystery! Although there is no definite evidence yet, I believe that there must be other life in the vast universe!

I'm not guessing! The universe is so big that there are no surprises! Although it takes a lot of conditions to give birth to life, it is not impossible, and the earth is an example. There are countless planets like the Earth in the universe, is it only the Earth that has life?

Even if all life needs water, there is more than one planet with water. At present, there are only no planets with liquid water in the solar system, and there are many galaxies the size of the Milky Way in the universe, and there are countless ones that look like the solar system! Are you afraid that you won't be able to find a second Earth?

Although we can't find aliens yet, won't aliens with more advanced technology than us look for us? So far, there have been many things that resemble extraterrestrial spacecraft, collectively known as UFOs, and although 99% of UFOs are masterpieces of nature, aren't there still unproven ones? Aren't they alien spaceships?

To sum up, extraterrestrial life is definitely there! It's just not discovered.

A few days ago, some scientists said that they had calculated that the planets and star systems in the Milky Way galaxy are similar to the Earth-Sun. According to research, there are about 1% of stars of the same type as the Sun in the Milky Way, and at least 10% of them have planets, that is, 100 million stars like the Sun have planets.

So it will definitely be found in the future; /

Theoretically, there are aliens, although the probability of having planets forming creatures in the universe is very small, but the universe is so large that it is not excluded that planets other than the earth can also form creatures, so there are aliens. Basically, that's all it takes!

And there are so many alien sightings in the world, it can't be said that they are all fake, it is said that there are alien bodies of falling UFOs in the United States.

The universe is very big, and there are all kinds of wonders in the world, let alone the universe.

It may be because alien technology is more advanced than ours, and it is very easy to hide from humans, and we humans can't find them with their technological level.

Because aliens don't exist, humans can't find them anyway.

So far, there is no scientific basis for the existence of extraterrestrials. Therefore, human beings have been looking for so many years and still have not found aliens, which is one of the main reasons, and on the other hand, it is very likely that human technology has not yet developed to that extent.

Human beings have never stopped for outer space, when human beings gradually expand their understanding, they will look at the long-term, and look beyond the earth, human cognition of the universe is also very limited, at present, human beings have reached many planets.

But there is still no sign of life found on these planets, so for earthlings, it is still relatively lonely in the universe, so are we earthlings the only life in the entire universe, in fact, no, there are many scientists who believe that there must be some alien creatures in addition to humans, after all, the universe is so big, it is impossible to have only the earth in the entire universe as a planet suitable for life.

And scientists have never stopped staring at life in outer space, but in the years of extraterrestrial civilization, there has always been a question that has plagued scientists, that is, why do we have no way to search for aliens? Later, this problem was also explained by a scientific team, the scientific team said that with the earth as the center of the circle, and then draw a circle with a distance of one light year as the radius, the signal reception and frequency reception within this circle, these methods combined with a model is also established, through such observations, scientists have found why there is no search for extraterrestrial creatures?

That's because according to the data model that scientists finally established, we have no way to make a detailed judgment on the overall area of the planet that can be accommodated, and now the level of science and technology that all mankind has cannot do a comprehensive search, and even if it is such a large distance, but for the entire universe, we are only a small step, no wonder, why we have not found any other traces of life so far, although the current technology is very developed, But if you want to be an alien creature, you must use more advanced technology.

Because our technology is not very advanced yet, and it is unknown whether aliens really exist.

It is because the development of science in China is that it is impossible to detect whether satellite humans really exist, so this situation will occur.

Because the chance of life being born is too small, aliens may not exist, so aliens have not been found for so long.
