in the 1970's, the fbi did some investigation and experiments regarding 'cattle mutilations' that were supposedly caused by extraterrestrials. the result? they found that all of the reported 'mutilations' were caused by natural predators, insects, and what happens to a corpse when it sits out in the open under the hot sun awhile.

doritos was the first terran company to send an ad into space with the intention of reaching potential extraterrestrial customers.

(this, of course, explains their constant campaigns to get us to eat their products: they are flavoring us as meat products for their alien masters.)
