Astronomers in Hawaii (USA) called it umuamua, “the scout,” in the Maori language. According to Avi Loeb, director of the Department of Astronomy at Harvard University and author of a book The first sign of extraterrestrial intelligent lifeMaybe this messenger is the first sign of Extraterrestrial civilization.

Comets can change course when their ice melts by ejecting the gas; However, no trace of this interstellar visitor was ever revealed. But for other astrophysicists, the mystery does not necessarily imply the existence of a ship outside the planet Earth.
As for the astronomer, he prefers to provide a lesson in humility: “There are trillions of galaxies like our Milky Way in the observable universe, all of them combined. There are more planets and solar systems in the universe than we do in the universe than there are snowflakes on the planet. It should teach us a little bit of modesty. We are probably familiar and popular, and maybe we’re not the smartest in the neighborhood“. Oumuamua would also be a warning to mankind: Avi Loeb believes it could be a shipwreck or robotic probe, from the remnants of a civilization that has vanished.
