U.F.O. does not mean "Space Ship"

I really wish people would stop using the term U.F.O. when what they really mean is alien space craft. U.F.O. is an acronym for Unidentified Flying Object.

So there is no argument that U.F.O's do not exist. Imagine your are at a concert, and a Frisbee hits you in the back of the head. Until you turn around and identify it, it is a U.F.O.

Imagine you are at the zoo, and a monkey throws a turd that speeds through your field of vision. It's moving too fast to see, so until it hits somebody and they yell out the best word to describe it, it is a U.F.O.
(slow moving example of an Unidentified Flying Object.)
And for your information, there are no habitable planets close enough to earth to have a need, or a use, for what you would call a "space ship". To traverse the vast distances of time and space to get to this planet, my people use time machines. Then when we get here, we have to learn your primitive language all over again because you keep changing the language around. "Ax" now means "ask". "ah ight" now means "alright" We have to reprogram our databases to understand you. That's why we avoid contact. It's a pain in the ass.

All we wanted to do was surgically remove some tasty "meat" from your "cattle" if that is what you still call them. When we inadvertently encounter those of your species, we stick a probe in their anus in an attempt to discourage further contact, but you either don't get it, or you actually like it, because you keep chasing us like pre-teenaged girls at a Spice Girls reunion concert.

Wise up Earthlings.
