Aliens.

People seem to imagine that Aliens
would want to 'take over' or control the earth -
that they would even want to
communicate with us -
that they would not want to communicate
instead with elephants or dogs or dolphins
or snails, fungi or viruses -
that they would not say something like:

"What a strange, dysfunctional little world!
What strange forms of  'life' - subject to
'evolution'  by natural selection -  not to mention
that crudely hilarious system of
competitive sexual reproduction -   
Let's get away
from the deafening planet-sized moan
of a silly and failed experiment -  Let
the Unknowables sink back
into their grisly unknown.
Let's leave that dirty wee orb
and its sad little moon alone."

Of course, they wouldn't use anything
as crude as mechanics of words,
which is why they might find out all they wanted to know
from our satellites, from dying trees,
or trilobites or turds...
