Re: We're not advanced enough to understand "aliens".
"and yet any UFO sightings seem to be hearsay or recorded by drunks totally unfamiliar with how their phones work."
Yes, it's weird. There are billions of cameras out there nowadays and almost NO ONE seems capable of finding somewhere to steady or rest their phone or camera in such a way that they can get a steady and unblurred still or video of a "sighting". I don't think I've seen a single video of a purported UFO or other UAP that's actually capable of being properly checked or analysed, even so-called "mass sightings" that are claimed to carry on for a significant time. All the video is shaky. Lets not even bother going near the landscape/portrait argument or overuse of digital zoom :-)
