ELVIS.
Of course the Aliens Dig 70s Vegas.
Anyway have you at all considered that the aliens are not actually intergalactic teachers sharing knowledge, but possibly they are the space equivalent of a juvanile deliquent driving his dads spaceship, as they cruise past primitive planets picking on wierdos (wherever you go, they ALWAYS look the same) and reveal their basic tech to them in the full knowledge that nobody would believe them...
Or, as Douglas Adams wrote... "They walk up and down making 'beep-beep' noises. Its a bit childish really"
That small paragraph in Hitchhikers Guide seems to explain decades of UFO sightings, without once dropping to enjoy the obligatory Anal Probe jokes...
