So sunsets are spiritual how? Maybe if you're a pagan sun-worshipper, other then that sunsets/sunrises are merely a (only sometimes) colorful short-term event.
I'm of Southwest Ontario since birth, a Great Lakes native of at least five generations. I have seen lots of wonderous sunrises/sets, storms, clear night skies, rainbows, the milky way when I was younger (it's not in our sight line up here now, coming back soon apparently) changing leaves, snowscapes, Northern Lights, and well, many things that are rareish and attract the eye.
I've seen clouds that look like Angels and faces and enormous white ducks for that matter, interesting, even conversation starters for that matter, but spiritual, no.
Hubble shots of colliding galaxies or the Cats-Eye Nebula blow my mind too, but don't ever make me jump to "unseen God must have did this" thoughts.
As many scientists have expressed: The Universe is wonderous and vast enough that Gods only limit it's scope.
At least Earth/Sun/moon/sky/nature religions concentrated their belief on what is, giving us an understanding of our enviroment. Giving us the tools of timekeeping/calenders, planting seasons, navigation and keeping us rooted to here and now.
You have stories, antiquated and useful in value only as any other ancient literature.
