alien artifact

Otherworldly ancient object

An alien artifact is an object believed or imagined to be made by extraterrestrial beings.

The term appears most often in science fiction, conspiracy theories, and speculative archaeology: The monolith in 2001 is cinema's most iconic alien artifact.

Claims about alien artifacts on Earth—from ancient structures to alleged crash debris—lack scientific support but fuel persistent popular fascination.
