the gathering of static electricity from atmosphere by ufo alien or USA craft possible unmaned

I was 12 yrs old. I was camping in the back yard with 2 friends. Sometime during early morning with a full moom I woke up and I was already sitting up. The sky was clear and lit up by the full moon. 
I was looking south at same time I woke up a disk shaped object was moving eastward in the sky approx 450 yds high and approx 200 yds away from me its size was approx. 1800 sp ft. disk shaped with a dome with what I thought were windows at the time with bright yellow light coming from the windows  ( I have since determined that the windows were heat vents and the yellow light was a high voltage} It was gold in color and at a 45 degree angle. Now here is what really caught my attention. Out of the bottom (which I could not see) came out 2 different color ( I thought) plasmas one gold or copper and one green around the edges of the plasmas (big blob shape) were looked like roots of trees on both blobs I could see thru each of them they pulsated in opposite resonances for approx 1 minute then stopped the disk shot away at remarkable speed at the 45 degree angle (in the blink of an eye)  Since I was 12 yrs old grew up on a farm I had no idea what that thing was nor did I know what a space ship was, but that has stuck in my mind for years  I have since discovered that the green plasma ( I thought) was in fact the same as happens at the north pole with the lights   a photon or free eletron is traveling and come in contact with a strong magnetic fields flux line and is speeded up and becomes a fast photon or electron and hits an oxygen atom and gives up a green color which is visiable   the copper color I have not figured out yet but must be a secondary electron transfer  since I suppose the ship was charging itself someway. It made no sound I have not told but a few about this thanks
