In Q post 2222, rather than confirming the existence of aliens, I believe Q is referring to the Fermi Paradox -
"Fermi's Paradox (i.e. Where are They?):
The story goes that, one day back on the 1940's, a group of atomic scientists, including the famous Enrico Fermi, were sitting around talking, when the subject turned to extraterrestrial life. Fermi is supposed to have then asked, "So? Where is everybody?" What he meant was: If there are all these billions of planets in the universe that are capable of supporting life, and millions of intelligent species out there, then how come none has visited earth? This has come to be known as The Fermi Paradox."

It bugs the craps out of me that David Wilcock type faggots use this drop as a confirmation of their little green men fantasies.
If one 'considers the vastness of space' they should be everywhere but they're not. They're just fucking not.
