Regardless of the truth of the alien thing, there is enough evidence that we have tech so far beyond our comprehension that if that was used against us, it would be indistinguishable to alien tech (or at least our scifi ideas of it). I don't think we need "project Blue Beam" to enact Battle of Los Angeles Part Deux. I would not be surprised if something like that was coming down the pipeline.
The "Precipice" has to look pretty damned Precipicy to make it be believable to everyone on the planet. Some bigger versions of tictacs would fit the bill nicely imo.
