why are UFO's only found in america?

Better question, why do they always seem to abduct people for the sole purpose of perfoming cavity searches?

They're not. There are plenty of reports from European military pilots, normal citizens, and crazies. Basically just like there are here. Many have been seen in Mexico and South America...every continent has stories of UFOs

To add to Crash's intelligent observation...why do they only abduct White Trash Americans for the sole purpose of performing cavity searches?

Wrong , when I was in Europe there was many things blowing around in the sky that could not be identified , especially during a gale in Hamburg , Germany .

They are not found only in America, UFOs

have been found or seen in Mexico, Russia, China, Europe and in Asia!!

actually there was a book about aliens that i saw in school and they had a map of where UFO sightings occurred and they were all the world.

Because Michael Jackson is still in the US.

becus america makes it up aliens aren't supposed to land on earth until....

but in the case of george bush its cus he gets visits frm the aliens he really oignated frm

Their mission was to find a way to assassinate Bush but they all failed, that's why they've been seen mostly in the US.

Because us Americans are crazy.. thats all that needs to be said =)
