In all seriousness, this a question of great interest for me, too, and I'm playing with it for a quite some time. Trying to answer it or at least starting to search for the answer steered me to astronomy, thinking going deeper on that front may bring me closer to the answer, but it was a bit too much for my younger self, so I continued to dig that issue on a more casual level. This doesn't mean that I don't spend considerable amount of time thinking about it today, and will put that issue to rest any time soon. At the core, this kind of questioning brought me to here in life, and I'm not gonna let this side of mine to rest or whither and die.
