Saucer like craft followed me home from work and hovered over our home while my wife and I watched..

I was working from 3:00 PM until 11:00 PM at the Spartanburg SC Main Post Office. I live about 30 miles south of Spartanburg. On my way home from work, I spotted a bright object to the west. It did not look like a plane. It was traveling at a low rate of speed and seemed to be following me. I continued to see it until I pulled up into our driveway. It came and hovered over the front of our house and projected a bright beam that lit up our front lawn. The object was round and you could see light coming from around the top, like it may have had windows around the top. It didn't sound like a plane or a helicopter. It made a humming sound. I got out of my car and went to the door and called my wife. We watched it for at least 5 minutes.
When it left it seemed to just dart it was so fast. There was no increase in the sound of the humming when the craft moved. It could change direction in a split second.
I think I have seen one or two more of these craft, but it was at a much greater distance. I couldn't see them very good.
I DON'T KNOW WHAT THIS COUNTRY IS WORKING ON BUT WHAT MY WIFE AND I SAW WAS ALMOST UNREAL. THEY MUST BE SAVING THIS THING FOR THE BIG BANG. THEY DON'T WANT ANYONE TO GET A HOLD OF IT AND FIND OUT HOW IT WORKS. I DON'T BELIEVE THEY ARE ALIENS.
Witness indicates that the date of the event is approximate.  PD
