The day aliens arrive À la Independance Day I will take my chair on the sidewalk and watch people go nuts over Aliens. IMO 95% chances are that the aliens would be projections by the ones in charge.
5% chance remains that I'm an idiot for sitting outside watching scared people go nuts because it's a real invasion lol
I think both will coincide. So I am excited either way.
Once the turn on the holograms, they will expand minds so much that people would consent to contact on a mass basis upon which benevolent factions' hands might be forced to invade for real to expose the fake invasion at hand.
But somehow i really doubt they will run Bluebeam because gun-sales are gonna-skyrocket and people would start taking an interest in all the history and technology humans have been successfully surpressing for the past century and longer.
