So, the gov. knows about them. But they don't want billions of people freaking out. So, many years have been used to prime the public. Movies like ET, Star Trek, etc. Who would fear Mr. Spock? Then add scary movies like Alien, The Day the Earth Stood Still, etc. But we came out OK in those too. District Nine, Alien Nation, etc, they are already here. So, I hope they are more like Vulcans than Klingons. Wookies rule! Princess Leah can stay at my house.
