Who Are the Old Martians?

​She chiseled and chopped
Stone broke and kerflopped
And sunshine bespeckled my skin.
"What's this we've found
Buried in the ground
Of Earth's forgotten surface?"
 
She pulled and she plucked
Dirt fell and they ducked
"That old thing?" the back one said.
I turned toward him
And said with a grin
"I'm not quite all the way dead."
 
He screamed, she reached
At me, to teach
A lesson of history.
"These bones of those
From long ago
Are not our ancestors.
 
“Didn't you know?
The species that goes
From one planet to the next,
Settle them first
Until near burst
Are Old Martians, we call them.”
