Agreed, we should stop thinking of the ancients as merely "mariners and sailors - but rather a group of advanced beings that had knowledge of advanced technology well beyond our comprehension today. They knew how to fly, defy gravity and levitate objects. The irrefutable scientific evidence for this lies in the stone circles of South Africa." My writings summarize some of the extant lore on their technologies.
One issue I'm confused about is: In addition to the stone circles and gold mines, was there evidence of major "civilization" settlements in South Africa?
