This guy should make a movie or scfi-television series about this subject matter. tweak the story a little so it won't be like V. At the end of the day I simply can not believe this until I see proof. Until I see an actual alien shape shift and communicate via the media or the net. I believe the aliens that are visiting aren't in the business of having a profound impact on other alien cultures. Any interactions with sentient species are for the benefit of their races or factions within their race... whether it is for resources, for science, for fun, or because they are curious.
