Although they are presented as harmless, goofy explorations of inane historical side-notes, cable TV specials such as Ancient Aliens and The Lost History of Ancient America normalise expressions of racist intellectual attitudes towards native peoples.
Their basic premise remains: ‘These primitive brown people couldn’t possibly have contributed to our cultural history! It must have been [aliens / giants / prehistorical Europeans]’. Indigenous peoples in North America, Latin America and Africa were practical metallurgists, experimental chemists, civil engineers and urban planners - restoring native peoples to their factual place in human developmental history reveals a dazzlingly beautiful archaeological narrative which throws grubby crypto-fascist conspiracy loons into the shade.
Busting these absurd, revisionist ahistories is an anti-racist duty.
