- Aliens already flew to Earth in the distant past, even before people could establish the first civilizations, and after that our planet ceased to interest them;
- Perhaps space travel is not as easy a task as it is believed and extraterrestrial civilizations cannot travel too far to Earth;
- Perhaps some alien civilization has only recently mastered the nearest space and has not yet reached interstellar travel;
- Maybe the aliens deliberately do not want to explore deep space, or maybe they even all died as a result of some disasters.
A new study suggests that our planet and its inhabitants are not at all interesting for representatives of extraterrestrial intelligence.
Astrophysicist Amri Wandel of the Hebrew University of Jerusalem has published his new scientific paper, which has not yet been peer-reviewed, in which he offers a new answer to the famous Fermi paradox, writes Live Science.

Wandel believes that the aliens did not contact us because they did not find signs of intelligent life on our planet. Thus, the scientist offers an answer to the Fermi paradox: if alien civilizations exist, then why didn’t they make contact?
According to the scientist, aliens are not interested in planets that simply have life. If life exists on many planets in our galaxy, then extraterrestrial developed civilizations are only interested in those planets where there are signs of very advanced technologies. And most likely our Earth is not included in this category of planets, because its inhabitants are not representatives of a reasonable species, according to aliens.
Many scientists have long been trying to find out why aliens, if they exist, have not yet declared themselves to earthlings? At the moment, there are several popular theories:
But Wandel believes that intelligent life in our galaxy not only exists, but is quite common. According to him, most likely, alien civilizations will not send signals to everyone in a row, but will choose for this only very interesting planets for them, on which, as they believe, really intelligent species live.
And a very advanced technology can serve as a sign of the intelligence of a species. Although, it would seem, they exist on Earth, but we began to send signals into space not so long ago. Theoretically, signals from Earth could reach planets that orbit about 15,000 stars. But there are about 400 billion stars in our galaxy. That is, our signals could simply not reach representatives of highly developed alien civilizations, and therefore, even if aliens know that there is life on Earth, they do not know that it is intelligent.
On the other hand, it remains the possibility that the aliens did receive the signal, sent us a response, but it has not yet reached the Earth. Also, according to Wandel, potential aliens may simply not decipher the message that earthlings sent them.
The scientist believes that there may not be so many highly developed civilizations in our galaxy, but it is likely that new signals from Earth, they will still receive and be able to understand them.
According to Wandel, most likely there are no intelligent species within 50 light-years of us, but they live further and are just waiting for us to announce itself as a civilization that has already begun to explore space.
Focus has already written about a theory that suggests that we have not found any aliens due to the fact that they are all themselves destroyed.
