I'll be the first to raise my hand.

The Hypothesis in it's varied forms i.e. Extra-Inter-Ultra Dimensional--Tonnie's Cryptoterrestrials to some degree--seems to finally be coming of
age after many years of basically being shunned. So I'm very interested in an informal survey of sorts here.
For those of you who have switched or converted, feel free to just simply state that you have or--even better--give some of your reasons for doing so.
Cool links ALWAYS appreciated, too!
My own journey was a long one. First, as an adolescent, I had to decide if the subject had any merit at all. Once I had decided for my own self that
some anomalous airborne objects were a probable reality, I fell right in line with the popular conception and framed my queries along the
Extraterrestrial line.
Then came Von Daniken and Chariot of the Gods and it seemed to make some sense of the other mysteries, the ancient ones, that also intrigued me.
My own sighting, along with 3 other Boy Scouts, at age 14 challenged the above concepts...although I wasn't ready to give them up yet.
That experience briefly: Camping out in some Appalachian foothills we observed a brilliant double-flash that emanated from--and illuminated--the
entire top of an adjacent peak, a split second of darkness, and then maybe 100 ft over the tree tops "it" pulsed into life. Perspective wise, I
would say it was about high-moon size in appearance.
At full pulse it looked like a globe of molten liquid metal or plasma sloshing & swirling around inside. Then it would dim at about the same speed it
lit. It would dim to nothing and we couldn't see anything and then a good bit higher in the sky it would PULSE to full-lit life again a few seconds
later.
Not counting the double-flash of the apparent lift-off, it lit and dimmed 6 times, each time higher in the sky and after the 6th nothing. We watched
for a long time, but that amazing glimpse was over but for the heavy-duty questions it raised in me.
The thing that bugged me for years was that it seemed to be more alive than something nuts & bolts. But I still hung on to the ETH/AA strains for
awhile.
Somewhere along the way I read some of Jacques Vallee's stuff and, although I found it interesting, I still wasn't ready.
But the years progressed and the more I researched the phenomena--in it's totality--the less and less the ETH seemed to make sense.
What was it that finally made me accept that some form of the
Interdimensional
Hypothesis was a much better fit?
Hard to say, but Prof. J. Allen Hynek's subtle shift away from the ETH, Dr. Jacques Vallee's
Passport to Magonia, as well as his
Five Arguments Against The Extraterrestrial Hypothesis, and the
High-Strangeness factors of many UFO encounters are some easy examples of the things that either
influenced or validated some of my own thinking.
There's sooooo much more, but I'm ready to stop boring you with my reasons and hear Yours!
Oh, one more thing: Of course I expect and welcome all dissenting views from the Arch-Villian Skeptic to the ETH proponents, but I'm much more
interested in the survey aspect of this thread concerning those who have adopted the hypothesis and/or switched over.
Fire Away!
