I recall listening to clips of all the presidents talking about UFOs. Their existence is undisputed. What they are, however is the issue. The mainstream media always pushes Evil-ution with their conspiracy theories that mankind originated with a rock.
I'm of the opinion that they believe and promote a lie which empowers the fallen angels. They masquerade as highly evolved physical creatures depicted in sci-fiction. This gives them more persuasion in their psyop. Here's what I mean. Republican Ronald Regan is speaking about them as a way to "unite humanity" as the United Nations wants control over.
Satan deceived Regan regarding this, is behind the United Nations altogether as he is the so called space aliens.
