Query: 'Heavy debunking by Korf

This is no objective analysis of the Billy Meier case. Korf does a lot of mudslinging and debunking. I have a lot of insight into this case and I believe that Britt and Lee Elders did the definive investigation many years ago. The conclusion of Elders was that Billy Meiers photos and films were genuine after have been analyzed in laboratories in USA.It is my firm belief after viewing the evidence that Billy Meier has indeed been contacted by a woman from the Pleiades called Semjase.
