Sweet Earth, each molecule of me has
come from you.
Sesame seed, broken into amino acids and calcium,
became my tiny bones; bananas, potassium,
the cells of my brain.
If we could trace each atom back, we'd find
Kansas, Iowa, Ecuador, Spain.
And further still, through unimaginable millennia,
these same atoms --the very same-- were flung from a supernova,
only to recombine, here, on Earth.
"Of star-stuff, are we made." Carl Sagan said.
And then (when I'm dead)
the same in reverse:
the atoms' slow dispersal:
pulled in by roots, washed by rivers, melted in magma,
blown, finally, to smithereens by the exploding sun....
Star-stuff, once again, become.
