This what I actually said before in my previous post, and below I am enlarging on that comment:
"If we assert that there has never been anything extra-terrestrial in our skies, then by definition, nobody can be trained to recognise anything alien."
I think we are getting tied up here with semantics and loose definitions. Since time immemorial, claims of UFO sightings have been supported by the term "trained observer". when those reports are made, and the claimants along with readers of them, haven't a clue what that term really means, and and assumptions are casually made because the observer happens to be some kind of recognised technical official, scientist, or some other category of profession where that claim might rationally stick. There are clearly some activities, where "observers" are trained either formally or informally through training or experience, like army snipers, bird watchers, or animal photographers. etc, etc, compared to the ordinary man/woman in the street, but there are no UFO "trained observers", professional or otherwise, in my view. Can we now put this one to bed, without any unnecessary hysterical debunking reaction, from the likes of GF.
