There was about 8 balls of bright light when suddenly it started to change and it formed a triangle.

I was at my home with my mother and my brother. I decided to go outside to look at the sky when I saw about 8 balls of bright Green light that then turned to white light. After three minutes the line of  balls started to move and they formed a triangle. I runded inside to tell my mother to come out.  When she came out the balls where gone.  She tought that I was crazy and that I was just Imagening UFO'S becuse when I was little I started to be interested in UFO'S.  After almost a week I saw the same thing again, but it did not last that much time.  I know that I am not crazy.  After seeing the report of channel 13 about the Seattle reporting center I decided to get on the internet but my computer didnt work so I used the schools computer to contact.
