How open-minded are we really?

Granted, this is not a post about anything Sanskrit, even though I can easily find a link to it (the "vimanas"...).
I have "stumbled" onto a video made by Stephane Allix, a French war journalist who decided to take on the subject of "aliens" and prove once and for all that it's all bogus. He has written a book on his discoveries and made a documentary (further down for the link). He was particularly interested in the work of Jahn E. Mack, a psychiatrist at Harvard University (not your average lunatic) who studied a good number of cases of so called "alien abduction". His view of the phenomenon is the reason i'm posting the link to the videos here (English).
