An out-of-place artifact (OOPArt) is an artifact of historical, archaeological, or paleontological interest found in an unusual context, that challenges conventional historical chronology by being "too advanced" for the level of civilization that existed at the time, or showing "human presence" before humans were known to exist.
Not as out of place as popular media would have you believe. Ancient civilizations had analog computers, automatons, steam engines etc the Romans were responsible for destroying most of it, they were only interested in weapons tech, set us back at least two thousand years.
