But aliens are already part of their lives for imagining they are coming to conquer the earth isn´t difficult. Both cartoons and comic books give them beliefs.

If a hoax or real disaster is easy to imagine and accept as true, the emotional reaction will be immediate and intense. It would seem likely that, in the face of such an unimaginable shock as an alien encounter, people would be stupefied and effectively paralyzed while their brains made sense of the paradigm shift. Perhaps acceptance is part of the brain’s desperation to make sense of the new world order. It would be interesting to know if the kids at the “alien landing site” got very quiet as they were being told about it.
