They are definately there aright! The first one I saw was when i was 13, i was on holiday in Monte Carlo, it was a cloud free night with a beautful clear moon in the sky and we decided to go to the open air cinema underneath the casino. Nearly there we realised that people were pointing at the sky and we turned to the right to look over the bay and there over the moon was this amazing silver streak. It was moving slowly and majestically over the top of the moon, it looked to be so far away, and thus enormous, as we looked it slowly morphed, the streak getting longer, and the shorter, then longer until it finally just went, followed by pockets of strange luminescence in the night sky, it was pretty mindblowing. Later on in my life i got stopped by strange lights on a lonely road at night, if anyone is interested i will share that experience with you.
