Late night thoughts

TBH an arch is much more complex an idea than an pyramid.

Neolithic people (technically bronze-age, but they didn't have any metal tools) in the Northern Isles were building three story high, bell-curved tower houses with two concentric walls called Brochs out of drystone at about the same time as the pyramids. Some of them are still standing.

Carbon dating of rocks tells you when the rock was formed and not when it was shaped.

Agreed, but there was no mention of middens or the like, just stuff found that were'younger' according to carbon dating.

Everything in my house is younger than my house apart from the structure. The big difference that the oyramids don't really have anything organic in their structure, just shit people dropped.

This is what's really weird:

Very hard stone - don't see how it could be done without a lathe. It's very precise, as one might expect from a lathed stone.

This thing is also a complete mystery:

Made from schist, i.e. 6.5 to 7 on the Rockwell hardness scale.
Why and how? Some kind of hydraulic pump, I suppose. But how did they make it?

[stinkwheel]

They traditionally cut jade with a mud saw made from a piece of string. Neolithic people ground flint axe heads.

Don't underestimate what a hard abrasive and plenty of time can do.

They could have chewed through it for all we know, but they had the Nile. All you've got to do is set up a water-mill and a pulley. Put 2 wheels against each other and you've got gearing. There's your lathe, or your grinder. That's what I think may have happened.

They had enough time to clear boulders off roads by repeatedly building hot fires around them until they were really hot then dousing them with vinegar until they fractured.

Hell, we made a canal network in the UK using Irish people with spades and wheelbarrows.

With regards the vessels made from really hard stone ... there are narrow necked vessels with wall thicknesses which are perfectly uniform throughout the vessel ... there are no modern techniques available which could perform this sort of operation ... supposedly.

Another mystery ... the granite sarcophagus underground at the Sarapeum of Saqqara ... ranging in weight between 70-300 tons ... placed into alcove below the level of the main central tunnel ... very little room to manoeuvre ... how did they get there?

Construction wise, the absolute precision of the flat surfaces, parallel and perpendicular to each other, both internally and externally ... the inside corners are perfect 90 degree cuts with no discernible radius ... with modern tools we'd be hard pressed to create something similar.

And all of this done with copper chisels supposedly.

We "modern" people are very arrogant, we think we are the most technologically advanced version of the human race there has ever been ... electronics wise maybe, but the ancients knew a shit ton about how to do other things which we can't or require machines to do!
