12 year old sights Virden, IL UFO

I was sitting on the top step of the back stairs to our house at XXXX N. Noble Street in Virden, Illinois. Suddenly and with no noise at just above tree top level. The object was perfectly round with lights all over it. There were two rows of lights in the middle going in different directions and the rest of the lights were red and blue. After it passed I yelled back into the kitchen where my father was and told him that I had just seen a UFO. He hesitated for a second and said that it was probably a helicopter. I started to accept that but it occured to me that it made no noise at all and it was only over on the next street over. If it were a helicopter I would have heard plenty of noise.
Date may be approximate, although the witness does not indicate that fact.  PD
