I can only be impressed by those ancient myths as incredible yet provocative. Who in those ancient days could have testified of machines? I don't know how (unless the dumbing down practice of today's science cannot and will not approve of machines in the ancient civilizations)?
Right or not, these are ANOMALIES without a scientific advocate. It ALMOST seems to me that today's scientists are suffering myopia and can't accept "intelligence" in ancient peoples.
Look at it this way; no matter what is dug up from the ground and what is studied in those ancient texts, there are subjects that are either NOT classified (to protect their careers), or they are stalling so as not to "upset" the apple cart. Either way, unless those anomalies are addressed, there will be no advances to negotiate amongst the lead scientists about the testaments so speckled upon the clean floors of archaeology and epistemology.
That's my take on this concern.
