To date, not a single evidence has been recorded that aliens really exist: all the facts in the hands of ufologists can be called speculations, rumors and coincidences. As for the real evidence of the life of humanoids, scientists do not have them in their hands. We only have to suffer from the unknown.
The worst thing is that ephemeral hints do slip through from time to time. Thus, mysterious radio signals regularly come to Earth, which can be interpreted as bursts sent by aliens in order to get in touch with earthlings. But they can be produced with the same success by galaxies, especially since experts have not yet established their exact source.
In the next 10 years, a global network will be created that will operate on the principle of the space Internet, that is, earth specialists will track all signals emanating from all corners of space.
But the problems of finding extraterrestrial life will not end there. If aliens do exist, their intentions in our direction can be both peaceful and aggressive. No one guarantees that representatives of extraterrestrial civilizations with good intentions will land on our planet and want to establish contact with humanity.
They can also be brutal invaders who will turn us into slaves. Ufologists warn: we need to be prepared for any surprises and troubles in the event of an alien landing on Earth.
