Archaeologists have linked Graham Hancock's claims to "racist" and "white supremacist" ideologies from the 19th century, which they say are insulting to the ancestors of indigenous peoples who built the monuments. A Maltese archaeologist who appeared in the episode said that her interview had been manipulated. The Society for American Archaeology (SAA) objected to the classification of the series as a documentary and requested that Netflix reclassify it as science fiction. The SAA also stated that the series repeatedly and vigorously dismisses archaeologists and the practice of archaeology with aggressive rhetoric, willfully seeking to cause harm to our membership and our profession in the public eye; ... the theory it presents has a long-standing association with racist, white supremacist ideologies; does injustice to Indigenous peoples; and emboldens extremists.

While it is true Graham is a polemicist and media hound much like Michiu Kaku or Professor Dyson I think a prehistoric advanced building civilization is a 'holy grail' worth searching for that existed prior to the latest ice age. The ancient Egyptians called these people the Zep Tepi. It is also true That Hitler and Himmler did search for some archeological evidence of a master race but that is certainly not what Hancock wishes to do.

In short we shouldn't throw the baby out with the bath water.
