Another watery location for our list, and given the evidence so far, it's not at all surprising. Although this particular potential location might be even more controversial than the others - just up the coast from Los Angeles! Honestly, though, if we were aliens we would just hang out in LA itself. There's so many freaks in Hollywood these days, you wouldn't even stand out.
For those who aren't hip with the lifestyles of the rich and the famous, Malibu is their ultra-rich playground, about 30 miles west of LA. This is where the scenesters have their all-night parties, there are hot tubs and infinity pools as far as the eye can see, and aliens... well, aliens just might have a base right off the coast, in spitting distance of Leo DiCaprio's pad.
