What does anyone know?

What do I know?

The origin
of the universe 
its scale 
its destiny
are beyond my understanding.

This earth 
so rich
so poor
so vulnerable
so uncontrollable
is all we have.

I accept
that I am less than a speck
in the sandstorm
of stars.
I only know
I am a citizen of earth
and this,
my brief home.
