And maybe the next generation will think something else....

This could go on a while I'll put the kettle on.

Well a theory that some dismiss because they cannot explain it.

Including yourself.

yes with perfect angles too, absolutly incredible and the top stone to fit precisely into a groove. Fancy buggering that up with your copper chisel and asking for another stone to be brought to you.

They achieved that kind of precision at Machu Pichu. Not hard when you know how.

Not hard? OMG

After centuries of experience i imagine they found it relatively straightforward. Inca cities are remarkable for their accuracy according to their limited technology, and folk turn up to dismiss them out of hand and claim aliens must've done it for them. Madness.

Have a look at The Natron Theory by Marcell Fóti for another plausible method Egyptians could've used...

Nose-nothing is in a negative loop again.

He loves to repeat things. Maybe he’s ignored at home.

Hardly likely to "bugger it up" when chiseling granite with copper.

Making it a solid (if not rapid) implement for the task

Plenty of room for error I am sure. Now I am no stone mason but I suspect that these skills would take a lifetime to master and if the average lifespan in that era was only 35 years old there. couldn't have been many with such a skill set around.

I know a stone mason, he’s top of his game.

There’s lot of work using some power tools in those few bits.

He laughed at a copper chisel!

A mate of mine is a stone mason, he works in his family business making headstones. I will ask him what they. use on Granite. I doubt it would be copper. I imagine every blow of the hammer it would need re shaping and sharpening.

You misunderstand average lifespan
