Have any body seen UFO's

There are you usually no such thing as UFO, but science can never tell. If you really wanna study about them go to yahoo search engine and type down UFO then it shall appear alot of them. Usually there is not UFO but like i think the government is hiding from us. Like for instant area 51 it does exist doubt. why don't you try that area 51 on yahoo search engine. It would been a very very good idea to like asked other people that have been encounter with them. Or somtime they leave signal behind like around texas or somthing. Somwhere that have cows and a farm they usually stop there.
