They are actually UFOs disguised as Ball-Lightning, steered by a thirsty
bunch of aliens.  They fly in tight formations to distract us humans, and
while we are watching them, their other UFOs, disguised as fireflies, sneak
up on us from behind and steal our beer.

WHAT!!! the Bastards!
so that explains why on a saturday night I claim to have drunk only 3 beers
yet there is a dozen empties next to my chair!! Bloody aliens stealling my
beer!
