Highup, I would still love to see the pyramids some day. From some ancient graffiti they found near some of they pyramids, they believe they used ropes and sand to cut things (rubbing the ropes over the sand cut through the stone) and attached to heavy things on ropes to help lift/move them. But, they would have needed the right wind conditions.
I've always been fascinate with ancient civilizations and their structures and technology. Egypt has always been one of the places that appealed to me. When my father went there, he had the tour guide who often appears on television documentaries that air in the US. My father loved to collect knowledge and was interested in many subjects. He had a Bachelor or Science degree in Philosophy (he said he took it because it was the fastest way to get a BS so he could get a federal law enforcement job). Later on he got a Master's degree in Invertebrate Zoology, but he also was self-taught about Geology. He was able to tell which rocks would have fossils and so forth. So, when he was on that tour, he started pointing out the different types of stone to the tour guide and telling her the geological info on it.
There's all sorts of stuff that I think people used to know almost inherently that has been lost due to training people to do things in different ways and be more reliant on tools. But then, ancient civilizations had a lot of knowledge that has been lost. There was some tablet or something with writing that no one could quite decipher until a mathematician looked at it and realized it was ancient trigonometry that is more advanced than modern trig. I do wonder if ancient humans had what is called "magnetoception"-- natural perception of direction. A friend of mine who is severely autistic and didn't speak until she was 8-years-old eventually started talking and went to Caltech. She now teaches and participates in brain studies. She's always had a good sense of direction and when they did brain scans, they found that she has magnetoception and can tell which way is magnetic north and so forth. Now, maybe it's because she has what they would call a "neuro-atypical brain" but it could be a throwback. I, on the other hand, have a terrible sense of direction and get lost in doctor's offices and in my own town. LOL. Although, if the sun is out and I know what time it is, I can ballpark estimate direction by the sun's position. But I can't remember road maps worth crap. LOL. So, navigation console in my truck is great.
