In an interview to Jacques Vallee( Heretic Among Heretics: Jacques Vallee Interview – UFO Evidence) he said and I quote:
“Vallee: When I met Stephen Spielberg, I argued with him that the subject was even more interesting if it wasn’t extraterrestrials. If it was real, physical, but not ET. So he said, “You’re probably right, but that’s not what the public is expecting–this is Hollywood and I want to give people something that’s close to what they expect.” “
So we have been bombarded with images of a myth that is very far from reality, many people had confused these images watched since childhood with reality and that is one of the “problems” that we have in this area, people expectations are somehow the main factor that determines what is a “valid” sighting or not, that expectation is mainly one of a “mechanical” craft, that actually is an anthropocentric position that assumes that the medium used by any other entity to move will be similar to the ones that we currently use or we can imagine that we will be using in the future.
It appears that for people in general is very hard to accept that maybe this phenomenon have a “biological/aliveness” component, or that it is so advanced that all our current concepts or ideas are inadequate to describe or even understand the manifestations that many people are witnessing almost in a daily basis.
