It is truly incredible how much we do not know about our complex universe. It just reminds you the "you are not the star of the movie". There are trillions of other beings that each lives in its very own complex movie, one in which you are at best a supporting actor.
This simply puts things in perspective next time you think that you are the "star of the movie", that life behaves in a way just to upset you or please you. With all due respect, you (or I or any one) are just one of 7.2 billion other humans and trillions of other beings on a tiny planet near a tiny sun part of a tiny galaxy that is one of billions. We, and our whole planet, are but a grain of sand in an endless desert. Things happen, they don't happen for or against you. You are not the star of the movie.
While the video is really bad (I suggest you just listen to the music), Iron Maiden fans will find this classic guitar take on "Fear Of The Dark" truly incredible. For those who are not Iron Maiden fans, well . . it is about time!!
