Sagan

isn't it amazing
the molecules that make up our bodies
were forged in stars hundreds of billions of years ago
and all the atoms inside you have been all over the universe
parts of you have been on countless other planets
but they all came here at this time to make you
and all the atoms of me and all the atoms of you
have flown across the universe in and out of stars
through the cosmos for millions of years
to find each other on this lonely planet
on the arm of some lost galaxy
