From Jim Marrs ""Alien Agenda", p. 531 in 1997 paperback edition:
Still an enigma.
In a 1971 news conference Hoyle stated, "Human beings are simply pawns in the games of alien minds that control our every move. They are everywhere, in the sky, on the sea, and on the Earth .... It is not an alien intelligence from another planet. It is actually from another universe which entered ours at the very beginning and has been controlling all that happened since." Hoyle added that many of his scientific peers believed in the existence of such nonhuman entities, but declined to say so publicly.
Still an enigma.
