One long-standing critique of science fiction (and one that I keep returning to) is that its “aliens” are typically humans in drag. Is that a bug or a feature? This thumbnail portrayal of a future post-apocalypse extraterrestrial archaeologist is dead on, assuming said alien would be much the same as a human archaeologist.
Of course, that’s the point. Human “aliens” give us the opportunity to confront ourselves from the outside, providing a safe space for commentary, criticism, satire, humour and demonstration. If they were truly alien, it would be a story about ants. Or cats. Or dolphins… you get the idea.
