The Last Documentary Fossil

In 2118 an alien named X surveys the Earth in his flying saucer. In this wasteland, where humans have long become extinct due to heavy pollution, he finds a bunch of rotting ‘image fossils’ (old, discarded films). X is puzzled by these images: Why are they building a machine that belches smoke? Why are there ribbon-cutting ceremonies? This is a sci-fi film in an alternate style.
