Hi everyone, new user here.
Firstly, I recently visited the Pyramids and although certainly impressive, they are not perfect, and were definately man-made.
Secondly, if you think about it, up until the beginning of the C20th there were no power tools or cranes, etc. so all structures up until that date
were in therory built using the same tools. Sure, materials and techniques varied and improved greatly, but there was no 'magic wand' to shift huge
weights or awkward shapes until relatively recently.
Awesome structures like St. Paul's Cathedral and Buckingham palace were all built without power tools of any description, so surely the Pyramids
could have been built by man, even if it was thousands of years ago?
I fear some people are blinded by modern-day science and can't comprehend any solutions that don't involve electricity or computers...





I
think it is because the pyramids are so massive, precise and would be hard to duplicate today.
