pin point light that brcame huge and got brighter, then whent pinplint in the sky and shot to the south

My father stoped to look for a canoue, on a road to rands pond, he went in to talk to the man about the price of the craft.  while we were waiting my mother and I were watching a,star or what seamed to be shimmering in the sky.
I said to my mother that it seamed to be moving and she said that stars seam like that.  then i said it is getting closer and my mother said yes it is.
It came from a pinpoint of lite dancing in the sky to unbeleveable light, lighting up the whole field it seamed to get as low as the tree tops and seamed to be as large  as the field I asked my mother what is this and she said i don't know. I jumped out of the truck and ran toward it, she screemed at me stop , and i did , and slip on the grass. then the light got so bright it was dificult to look at it, i ran back to the truck. and it went from huge to a pinpoint of light and shot out of sight.
when my father came out and we told him, he said impossible, i was not gone that long, i just akked him how much the canoue was.. they were inside.
This is my true story, my mother was their and so was i.  thanks for listening
