Xenoarcheology

The theoretical discipline concerned with the search for, and study of, material remains and artifacts left by non-human, extraterrestrial intelligences. It’s the ultimate cold case file, applied to cosmic scales. This isn't about digging up bones, but about detecting and deciphering the "technosignatures" of a civilization—whether that’s a derelict megastructure orbiting a distant star, the ruins of an outpost on a dead moon, or the puzzling geometric patterns of a long-vanished city. It requires thinking like a species that isn’t human.

*Example: In the movie 2001: A Space Odyssey, the team investigating the Monolith on the Moon is practicing Xenoarcheology. In a real-world sense, scientists analyzing odd stellar dimption patterns (like Tabby's Star) for signs of alien megastructures are engaging in a primitive, astronomical form of it. It’s archeology without a known history or culture to guide you.*
