Harvard astrophysicist Avi Loeb said the quiet part out loud while talking to Fox News Digital on Monday about UFOs, aliens and his ongoing research into extraterrestrial life.

Loeb believes that the proven existence of alien life should be enough to prompt humanity into a state of global unification, he told Fox. The idea is aliens would force humanity to consider ourselves a united species, rather than a diverse species who hate each other for largely mundane reasons. You’ve heard this idea before because it goes back at least as far as former President Ronald Reagan.
