We martians had it all figured,
a series of canals
traversing the whole planet.
A way to move produce
& also store energy.
Then the nosy earthlings
with their accurate telescopes indulged,
so everything went underground
like veins in all directions.
The planet surface
still needed to look uninhabitable:
all done with cosmic mirrors
& a bunch of desolate looking
desert billboards purchased
wholesale by one of our more
astral agents in Arizona.
