Skepticism Is Pseudoscience
The saucer shaped disks in holloywood films came about as a result of the sightings of disk shaped objects, not the other way around, and such sightings go back much farther than 1947 ... all the way back to the "wheel within a wheel" sightings of biblical lore.
Nope, sorry, before the Roswell "saucer Disc" craft, you had nothing of the sort that became famous enough to spread the fantasy, and only after thus did the crazy fad take off:
Pre 1940 you had clouds and circles and wheels, and all sorts of fun objects....but no saucers:
UFO Cases Directory: Cases by Decade: Pre-1940 - UFO Evidence
Earliest report in 45' had circular craft....and Arnolds look just like a Nazi Wing in June 47'
New Mexico UFO Crash Encounter In 1945 - San Antonio, New Mexico, United States - August 16, 1945 - UFO Evidence
Unfortunately it was Hollywood with all those creative minds who gave you the mass fad you all play with today.
And those triangle craft......Terrestrial: Most probably developed by Raytheon and E-Systems
Here's an excellent site for the theory that these craft are terrestrial in make:

Your offhanded dismissal of the stimulus response is nothing more than an attempt to devalue the experience of thousands of people. Furthermore, the evaluation of physical evidence is still dependent on elements of human perception and interpretation ( which in my view are some of the best tools ), and have already been applied directly to the study of the phenomenon by those who have directly experienced it.
Considering the fact that your so called "stimulus" response cannot be measured with any viable conclusive median, and therefore no changes can be utilized to project the variances in said constant, any and all response would be totally contradictory to that necessary base measurement. Without this initial base, where would any scientist be able to honestly weigh the differences and understand the relevance?
With physical material or fact based evidence based on non soluble differences, you have a base to compare....
Human behavior is a sliding curve to say the least.
Take for-instance the fact that you can place 4 human beings along a path in a forest, have them see before their eyes a scenario by which you developed, and after their walk, ask them what they had seen.....and none of them get the scenerio down pact, most attempting to embellish out of embarrassment, and this leaves open a slight variance to an otherwise unmeasured initial median (human behavior variances).....
Then a month later, ask those same 4 people what they had seen in the forest that day, and when they answer with a totally new amount of input, you have data bordering on an impossibility to gauge; and since you never had that initial median anyway, you now have absolutely nothing but chaotic variables muddying up what could never have been clear water in the first place....
Woops....I just made an assimilation to almost every E.T.H. and every E.T. wannabe story out there.
However if you want to take the element of human perception and interpretation out of the equation and rule that only a machine can make the determination, then you have to be sure that the machine can't make any mistakes, and we already know that machines fail all the time.
Huh?
Human beings and their varying perceptive reality compared to a machine (computer lets say), and then input data placed in a machine to discover a median....then the median used to observe the slopes and rises in future data....and then the hypothesis based on the fluctuations of the various input. Which would arrive at a definitive conclusion based solely on the data alone...leaving out human emotion, what you had for lunch that day which could have thrown you in a bad mood......etc.
No, in the case where "real" data is run under machine analysis and screened to find the appropriate answer, I'd take the machine over the human any day.
In the case of E.T. and E.T.H., since everything found is nothing more than human perception, neither a machine or a human being is capable of "guessing" at an answer, because without the proper method I wrote of above, anything found from this discombobulated and varying interpretation data would be nonsensical to say the least.
You can remain in a state of denial all you want about the ETH, but your simple proclaimations that it isn't true are far outweighed by those with the actual experience.
Once again, judging for the sake of writing doesn't make you right. The mere fact that science is there for us humans as a gift to use correctly, doesn't mean you can hope for the best, spin the bottle, and spew forth eyewitness reporting as some form of evidence.....sorry, but science refuses to be insulted in this way no matter what any martian wannabe hopes for.
