This very musical poem reminds me of three things: Carl Sagan's phrase "we are made of star stuff" and the hypothesis some cosmologist have that says that life on earth may have come from somewhere, like spores or microbes on meteorites and asteroids. Some even say that the life that could have existed on mars had its origin on earth after a big asteroid's impact send microbes and algae from earth into space.
Also the need of humanity to attribute everything to deities is express, to my understanding, here:
Nameless beauty—
Why must humanity abuse ye?
Through their grimy appellation
You become disfigured.
We deface the beauty that has no name when we force a name onto it, a name passed through the tainted sieve of our intellect.
The narration makes it all the more enjoyable.
Thanks for the beauty my friend.
