Something I like to add to the Meier discussion is this.
I was impressed by the book "Light Years" by Gary Kinder
in the early 90s? that I read it. [it may have been the
late 80s?].
Then I saw some UFO programmes - documentaries, which
always pooh poohed Billy Meier.
One in particular made the point that it was forced perspective
techniques that would have made the photographs possible.

I know that initially that this is possible, if you go
about using that technique, and have a model to do so.

So I was turned off Billy Meier and did not seek to
verify the claims he was a fake.
But around 3? years ago I was getting access to more and
more Billy Meier information.
I was especially impressed by the videoed lecture by
Wendelle Stevens in which he recounts his investigation
into Billy Meier so many years ago. Note - there is a
slideshow presentation with this, in which clearly it
shows the series of photographs Billy Meier usually takes.
Please note, there is a verification that he had no
tripod with him, nor other equipment, and he was there, at
the site for a short period of time.
And so - a lone one-armed cameraman, faking the photographs
does not sound plausible or possible.

I tend to be skeptical of what information Billy Meier
provides, and I will always seek verification of that
information.
And through verification, we'll know if what he was
telling us, was truthful or not?
