little gray men emerging from airborn thingies is HUGE in itself.
Um, no. A short guy in a grey suit stepping off a helicopter is a little grey man emerging from an airborn thingy.
Or did you go through all previous sightings and came to that conclusion in every one case?
No. I don't see the point in digging through all the reports, when the reports I have heard about have been so underwhelming. I was skipping around, watching bits and pieces of the video you linked, until Manfred pointed this out:
The geiger counter reading is reported as "10 times background," which sounds impressive if you've never held a geiger counter, but really just means a nearby rock had some potassium in it, or a dozen other possibilities.
So they basically lied. I actually haven't ever held a geiger counter, so I had no way of knowing this. If asked to explain it, I would have had to admit that something weird was going on that I couldn't explain. Except there's a perfectly mundane explanation, and the only reason I was confused is because I was misled about the significance of the reading in the first place. After that I didn't see the value in watching the rest of the documentary.
So I have a better idea. You tell me what you think is the single most convincing incident, and I will tell you,
Recently I've been struck with a belief in Aliens being present on this Earth. It happened after I watched this documenary (and subsequently several others). My feeling of belief is not particular interesting in itself - I could be lunatic or otherwise psychological dysfunctional. What I'm interested in knowing is to what extend other people, who consider themselves rationalists, feel belief in the existence of aliens on this earth, after watching this documentary. Is anyone willing to try and watch it and then report back?
Another question arising in this matter is how to treat evidence of extraordinary things. Should one require 'extraordinary evidence for extraordinary claims'? I somehow feel that this notion is misguided - it discriminates evidence prior to observation. That is not the right time to start discriminating. At most we should ascribe a prior probability of zero and then do some Bayesian updating to get a posterior. Hmm, if no one has seen a black swan and some bayesian thinking person then sees a black swan a) in the distance or b) up front, what will his a posterior probability of the existence of black swans then be?
