Meridiani Planum as an Ancient Bacteria Sponge Ecosystem (first draft)

When mother nature makes her list
of dinner guests worth coming,
she gives them each a heartfelt kiss
to keep their tickers running.

Her house, though humble, has no ghost,
but more than enough to see
and she would be an awful host
if scientists agree

to find out things that are not there,
or see what is invisible,
or make their ghosts from thinning air
on theories uncontestable.

She pities those that shut their eyes,
or ignore the facts before them;
her house can offer no surprise,
to those who will ignore them.
