A new Netflix series called Ancient Apocalypse shot to the top of the streaming service's rankings the week it was released. It claims that an advanced civilization which thrived during the Ice Age was wiped out by comets and floods, but left humanity with science and technology. In the world of archaeology, such claims aren't new, and are referred to by experts as "pseudo-archaeology." This episode of IDEAS unearths the long history of pseudo-archaeology, how it's been deployed to advance political and cultural ideas, and where it crosses over from pseudo-science to religious myth-making.
