Memento on the Moon

A boy from a distant galaxy does wander, calls home on his intergalactic transponder, stares into the black where countless twinkles swirled, at an unremarkable nearby world. That planet is, of all signs of life, long devoid, unless, by geology, it has been destroyed. More fascinating than just any rock or pebble, peering through his brand new spacesuit's bubble, lies before him, on this dusty satellite, a monument, illuminated by Sol's bright light. It bears a picture history. Could it be to mourn, or possibly, for future space travellers to warn, in a sequence of images so melancholy the consequences of one specie's folly?
