There is a band wagon being ridden and the riders are all yelling about what amounts to quality. The old academic lines are being trashed in the face of all kinds of very compelling evidence resulting from some dedicated intense studies of stone workmanship.
There at least two areas of this study and bandwagons.
The first has to do with lots and lots of Egyptian artifactual objects fabricated with extreme precision from stone that is of hardness unworkable by most today. There is solid and vast evidence of tools not known to exist. One such tool is what must have been a circular saw. There are lots and lots of saw tool marks in rather akward places for the traditional scholars. There are a series of very large stone boxes fabricated to extreme square and plumbnuss in locations far underground. There are all kinds of vessels made from very hard stone with a precision today of a computer controlled tool. and on and on
The first published examples date from about 1911 but were tossed out of Academic discourse.
The second band wagon is being ridden by commentators on the studies of megaliths. Outrageously large stone blocks were quaried and then transported for many miles. In Peru, much of the trip was uphill. The construction is then extremely precise with examples in Peru and Japan extremely extremely precise.
In both instances, the band wagon riders are postulating the work and events are prehistoric. That means that the work was accomplished with no record or evidence of the people who accomplished the feats.
I tend to agree that the traditional academic party line is just ignorance. I tend to agree that the work in question predates anything generally known. I have no clue as to who or when but I enjoy the bandwagon videos on Youtube made by some real technical scholars and increasingly videoed by what are secondary reporters.
Bottomline........ we just don’t know
Yes, there is a lot of evidence that some ancient civilizations had technology to do very precise work that would be challenging for us even today. However, I don’t think that fact alone supports some of the more extreme logical leaps to attribute it to “advanced technology” beyond what we possess. I tend to think that we are just missing methods that could have accomplished these feats with simpler technology; methods that have been lost to us since they were probably “trade secrets” among guilds that were never written down, and that have become obsolete over many millenia since we tended to move away from megalithic construction and on to easier to use constructions methods like brick and concrete.
