Craft[ very bright green in color ] rose up above trees in a highly wooded area,zig zagged[like a climbing stairs motion]floated directly above car.When i got out of car and looked straight up there was nothing there!

I was a married 22 year old with three sons [ twins age 5 and the youngest just 2. I was visiting relatives in Greenville South Carolina on May 11,1972 at approximatly 9:30 pm. I pulled the car off the highway and drove to a clearing where my cousin's trailer was sitting.As i stopped the car the engine still running, i noticed a green light moving up vertically to tree top level. It seemed to float up and stop, then all of a sudden it jerked to the left faster than anything i had ever seen, stopped on a dime, floated up, it did this motion 3 more times [ like a climbing stairs motion ]until the object was directly in front of the car. It then began to float over the car, my heart was pounding and my head was spinning, i was totally stunned!I cathered up all the courage that i could muster and jumped out of the car and looked straight up, there was nothing only blackness! I had my three small children asleep in the back seat.The one min. that this sighting took has changed my life forever, i no longer have the luxury of not beliveing.
