We were flying back from Los Angeles to Hong Kong when I looked out the window and saw this. It was just brilliant and continued for quite a while longer than I thought it would. Perhaps it was because we were flying towards the west, in the direction of the setting sun. Chasing the sun, so to speak, like 夸父逐日 in the Chinese legends.
Some would believe that such beauty is just a result of energy becoming elementary particles, which formed light atoms, which formed gases, which created heavier atoms and molecules, which formed stars and planets, which created clouds and other natural phenomena, all without particular purposes.
I find it easier to believe that God created all these for a purpose that we are finding out.
