Too bad the aliens didn't share the idea of metal weapons with them huh? While other cultures were using them, the Mayans were still using obsidian
tips... Somehow, I don't think aliens were involved with them at all...
Herein lies the real problem. With all of this construction, where are the tools?
Nowhere, in any of the sites of great stone building in Egypt, Mexico or South America has anyone found any tools.
Obsidian, in the case of the Maya, can certainly cut limestone, but how was it done?
Obsidian will NOT cut granite, so how was that done?
I live in one of the great granite producing areas in the country (South of Boston).
The way they cut granite in the old days was to score a line down the surface of a block of granite with a diamond tipped awl and then bore a 4 inch
hole at 12 inch intervals down that line. Then they hammered wood pegs into the holes and poured water on them, causing the wood pegs to expand ,
thus cracking the block down that line. These are NOT large blocks, like what we see in the ancient sites, as most are 3ft by 6ft at the largest and
then further cut down to other sizes.
All of these blocks that are just about everywhere you look in older construction (foundations, walls, curbs, facades), show these hole marks in the
edge of the stones, as they were just technically and economically impossible to reface.
So, with the Maya and some Egyptian construction perhaps they used a similar method to drill the rock using obsidian drill bits, but none of these
blocks show any of the evidence that this method was used, unless they painstakingly re-surfaced the rough edges of the rock, which means they would
have to do this to the entire surface of some incredibly large stone blocks.
With granite and marble construction, like Egypt and Machu Pichu --- there is also no evidence that this method was used... So how does a culture cut
such large stones, surface them within 1/100th of an inch of tolerance and fit them together like a leggo building?
Methods today use diamond embedded band saws , but it takes incredible machinery to do this, and to run the engines necessary to pull these huge bands
through the rock strata.
I cannot imagine anything else but a long forgotten technology that may turn out to surprise the hell out of us as to where it came from, and how it
was really accomplished.
