While questing for diamonds, Sierra Leone locals stumbled upon a set of enigmatic stone figures depicting several human races, and in some cases, semi-human beings. In addition to their mysterious origins, the Nomoli stones are incredibly ancient with some estimates dating them as far back as 17,000 BC. Another mind-bending facet of the Nomoli is the high melting temperatures required to create them and the presence of steel manipulated into perfectly spherical balls embedded within several of the figures. This suggests that the stones were developed by a civilization that would be considered highly advanced for its time. On this week's episode of Lost Origins, Andrew and CK are joined by Ben Vonderheide to rip into all things Nomoli. Ben is the world's leading researcher of the Nomoli and he explains the current understanding of the origins of the figures, their purpose, and the implications they hold for unlocked a missing chapter of human history.
