how?

How would one find answers to questions like, "what was that object we saw in the sky 1-1-06 at 1:30. It had an easterly trajectory and it was over Gainesville, Georgia. It was large and fast. It appeared to have no external lighting, only reflection of ground lighting. It was totaly silent and appeared somewhat cubical in shape."? If you could direct me to a source of info or a believable explanation, I would appreciate it. I think what we saw was maybe a satelite, or something man-made in an orbit around earth. Thank you for your comments and help in this matter. Mark A. Baehr
