This is true. A form of 'lime' that's still used today. It's puzzling why cement has replaced lime so much. Apart from setting sooner, cement is inferior.Now the ancient Romans knew concrete. They had concrete that set under water even.
I would tend to disagree, and yes, I am an engineer as well... here is an interesting video which makes no suggestions at a true solution, but pokes significant holes in the current theories.There are multiple videos. Just go to youtube and search them out. I found the link that got me started right on the YouTube home page, where they present currently and popularly trending videos. Start there, and drill down until you find it. It may still be on the hit parade list.
Cutting stones: There are hundreds of videos like this one on YouTube. This is not the video I referenced above.
If that's true you know meteorites are even tougher than iron.The Pyramids were bronze age. But the ancient Egyptians were aware of iron from meteorites. Egyptians believed iron to be a gift from the gods, and called it ‘ba-ne-pe’, which translates to ‘metal of heaven’, for at least 1,000 years before the earliest hints of the iron age, which goes back to perhaps 2,000 BC, and is certainly a growing enterprise by about 1,550 BC.
Iron meteorites were historically used for their meteoric iron, which was forged into cultural objects, tools or weapons.
In 2016, a scientific study determined that Tutankhamun's dagger is made of iron, containing approximately 11 percent of nickel and traces of cobalt.I think the age of steel goes back to perhaps about 800 BC. Iron really took off then.
Sounds like my jobThat shows they have a specific group of skilled people dedicated ONLY for this purpose. They were not meant to take part in any war or celebration etc. Or they exchanged holidays or non work days with each other. For example today you do my work on that pyramid today and on that celebration day you will take rest and I will do your work.
Yes that holy stone called "hijre aswad" is most probably a meteroite.From memory, the major religious shrine in Mecca known as the 'Kaaba' was built around a particularly large Nickel-Iron meteorite.
I heard more alien theories about Stone Henge than non-alien theories.Nobody ever promotes ancient alien theories about white Europeans building huge things. They always suggest they must have had some normal method we just don't know about.
Curious.
What “huge things” did white Europeans build? Notre Dame Cathedral? The Eiffel tower? Nothing compared to the great pyramids and yes, quite normal.Nobody ever promotes ancient alien theories about white Europeans building huge things.

You forgot to mention the White HouseWhat “huge things” did white Europeans build? Notre Dame Cathedral? The Eiffel tower? Nothing compared to the great pyramids and yes, quite normal.
