Earthlings are accustomed to communicate through oral speech - in the distant past, our ancestors interacted with each other using gestures, but now modern people have mastered speaking skills. But how do representatives of extraterrestrial civilizations communicate with each other? Ufologists decided to find the answer to this burning question.
Experts say that humanoids do not need to speak to be understood. If the atmosphere on their home planets is thin, then they have no need for votes. In general, aliens can differ significantly from those creatures that they represent the inhabitants of the globe. Since we don't know what conditions are present on distant planets, aliens can be anyone, even single-celled ones!
In order to understand each other, the aliens probably use specific speech organs that are absent from earthlings, or they speak through the transmission of radio and electromagnetic signals like those that scientists pick up with ground-based telescopes.
Ufologists also believe that humanoids do not need eyes, because they can do without the organs of vision. In general, there are many guesses, but there are no specific facts - until we see the aliens, then we cannot say for sure.
