World exclusive: scientology alien secret exposed - 2009-02-05
Scientology has denied for decades that it preaches stories about aliens infecting humankind.
It's been scientology's most fiercely guarded secret - but not any more.
In this audio tape, the founder of the organisation says: "there is a base on this planet and it so shredded away as to be hardly recognisable."
The tape was recorded in 1968 as Scientology founder L Ron Hubbard gave a lecture to the faithful.
