1. I didn't mean to include scientists in my original formulation, but because you have brought up a situation in which scientists have made a conclusion that is contrary to naive perception, then observations of scientists have to be included, in which case my original statement leads to concluding that the sun revolving around the earth. But that would be a mis-use of my original statement in a way in which it wasn't intended. We were talking about naive, everyday witnesses, not scientists trained in empricism, observation, etc. So bringing in a situation in which professional empiricists (?) rightly overrule naive perception changes the context inappropriately.
2. We aren't saying “It cannot be so, therefore it is not so," we are saying "It probably isn't so, therefore it's likely that it's not so." Duh.
1. Oh, so now you contend that scientists have better observational powers than the ordinary person because they are trained? Perhaps your fellow UFO debunkers can step in at this point and disabuse you of such fanciful notions... but of course they will not (!), instead they will uncritically accept a contradiction in their own argument just so long as it is seen to support their own belief system.
2. "We"? (see above). "It probably isn't so"? So tell me, how precisely do you calculate your "probability" to end with "likely"? Of course you do (and can) not... it is a mere statement of belief and of course that does NOT make it true.
