I agree with you that most of the sightings and people's experience of abduction are not true at all but are beliefs based on several different things one of which you mentioned as your friend's experience. But I think there are 1000s upon 1000s of reports and I can't help but wonder what if at least 0.5% of these were true. I don't know what makes us special that they would want to visit. Maybe there is something that we don't know, something so significant that they might be interested? But yeah, the whole thing sure is interesting :D
