Ok, so I'm having this debate with a pyramidiot and the drill holes keep surfacing every now and then.
It's kinda hard to argue to this specific argument because i can't find almost any scientific conclusions about stone drilling/cutting in Egypt except some pretty vague texts about bronze cylinders/saws and sand. Ok, there are a couple of vieos of reenactment of sawing a lime stone with bronze saw and sand but what about driling holes and especially about granite working?
I don't doubt that they probably used the same approach everywhere but shouldn't there be experimental archaeologyst reenacting these theories? And if there aren't, then why? What seems to be the problem?
Another thing I dont quite get is the quality of the holes, especially in granite, because this is the material repeatedly pointied out. So, we are shown those nice, even shiny holes, some of them with radial grooves that are supposed to prove that they were cut with a step of approximately 2 mm or something like that which should have been impossible by conventional methods.
Well, of course i doubt that the grooves are spiral which the sould be if they were to indicate the drilling speed and step. Has anybody studied them and pointed out if they are just radial or spiral? If radial, i could explain them very simply: after every certain time or drilling depth the workers replaced the old abrasive (sand) with the fresh one. Now the fresh one, being a better cutter either made a wider or narrower cut (not sure yet, which one; I suspect that in time the sand was powderized and got additional volume from both granite and saw itself and it started to cut these wider sections in drill holes because of the expanding volume but who knows (well, really - I want to know who knows, if anybody; that's why I'm here!)) and when it was worn out, it made the opposite cut. But if they really ARE spiral, then we're ********** i guess. I don't see an appropriate explanation for this.

Of course, even if the secret of these holes remains a secret forever, it doesn't prove that the aliens or ancient hi-tec civilization did it. It's obvious to rational people that if they had a tecnology to powercut granit as we are able do it only nowadays, they must have had other abilities too! It's not like you have a knowledge of power-cutting and you build the whole pyramid with hi-tec tools but you transport the stones on papyrus rafts and break them from quarry with bronze tools and live in mud huts and...well...in general wont leave behind any hard evidence of this at all. You know what I mean... Pyramidiocy is nothing else than a version of a God of Gaps.
But i'll wait for your answers to my questions. Thank you!
