my friend claims to have seen a ufo before, he was working at a gas station/grocerie store and for about an hour he hear a sort of like buzzing noise but didnt think any of it. hhhe went to take out the trash and when he went outside he heard it even louder and looked up at the roof and saw a very large round "ship" i guess and he said just as soon as he saw it the buzzing stopped and it zoomed away. then he said that when he went back into the store the other workers said that the lights were dimming on and off when the buzzing was going on.

i believe that story.
