Strange glowing Orb hovering in front of 12 year old boy!!

Im 25 years old and Im reporting the strange occurance that happened when I was 12. I was outside on the verandah of my parents villa and was looking up at the sky. It was just starting to get dark and everything seemed quiet all of a sudden. I was saying to myself at the time `It would be interesting to see a UFO!` And then a light came down diagonally from the sky and it hovered right in front of me!Itwas circular and shone like a mini sun. A light yellow/white colour. It also made a hum that you could JUST hear. So there it was hovering over my driveway, I was in awe, tried to shout to my mother who was cooking in the kitchen but no words came out. I freaked, then it started wobbling a little, moved slowly up in a diagonal position, then shot right up into the sky. If it had a pilot, 1 - 2 people could fit inside it. Bizarre!! Either Nasa has some mind boggling technology or...I dont want to think of the other explanation!
