Getting by the fact that Amazon have listed this book in the science section (when it should either be in science-fiction, or maybe just fiction) we are once again dealt a collection of tales concerning UFOs and those in uniform.
To folks genuinely of the skeptical mind/movement (and the word skeptic has been thrown around here as some praise for the author concerning the book) you will be well aware of the logical fallacy known as the "argument from authority" which is the common error of accepting claims (as true) from anyone in a position of "respect" - an assumption, which is quite simply wrong.
It's a regular occurrence, that opposing sides in a debate love to claim someone has crossed the line and become a believer in their mantra. Here, it's the "skeptical" author who's apparently joined sides with those who "believe" in UFOs. And this therefore, in their eyes, means that everyone who remains unconvinced must now be irrational fools. Sadly, the irrationality however remains with them.
You cannot argue with personal experience, which is something the UFO (and a host of other pseudoscientific) claimers cease to realize. If I were to make a claim I saw a ghost in my room at 3am in the morning it's more than likely I thought I did - but this does not make it true. In a situation like this the onus is on me to prove I did, not on others to disprove it, so here we see the flaw in these claims documented within.
There exists no evidence of UFO visitation to Earth or in our skies. Grainy pieces of film and written claims of witness do not a proven make. I've no doubt that a good majority of the folks herein DID feel they saw "something" in the skies around them, and this may even have been backed up by several other witnesses, but the problem remains that mass hysteria, or mass confusion, in understanding what a light in the sky (etc) might be doesn't mean it was of "alien" origin. This is another fallacy where if something can't immediately be explained as Earthly then it must be little green/grey men. Such rubbish! Just because something might not be explained right now should not leave people to assume it's paranormal (or whatever). This is pretty much the same tactic the religious use in their "God of the gaps" argument (ie. If science can't explain it then God must have done it. Of course those "gaps" get smaller every day).
The term UFO obviously means "unidentified flying object" but many do not realize that this is a descriptive term which exists only to underline the difficulty in identifying something at a given place and time - it does not mean SPACESHIP. Added to the fact that even if alien life exists (and I would expect it does given the size of the Universe) the distances requiring travel would be thousands of years at the speed of light (based on the locality of even the closest possibility of life sustaining environments) and this alone is the biggest factor against it happening. Physics my friends has defeated you.
So if little grey men were out there searching for life in their flying saucers they would have to set out for Earth while we were (at best) still in the caves. This planet would be emitting no radiowave transmissions and would seem as dead as our moon to anyone looking. But again, no concrete evidence exists of any of this. And just because a man wears a uniform does not make him an authority on all we see around us. Every one of us can be tricked by light, shadow, sound, and the (sometimes) illogical human brain. It's known that some professional military fighter pilots have even tried to attack Jupiter at certain times of the year thinking it was an adversary.
As a true skeptic, I will accept anything given the proper evidence backed up by review and research. This is the scientific way. But hearsay and blurry pictures (whether or not they come from a yokel, or a jarhead with a badge) proves nothing. And crashed weather balloons don't count either. The truth is out there for sure, but I'm guessing it's a little less astounding than some would love it to be.
