Imagine we wanted to make an exact copy of the pyramids in Egypt, the great pyramid specifically.
Never mind building them without machines. Do you think mankind, not just the current residents of Egypt, but do you think in this world there exists the technical know how and political will to even be able to do it?
they were built over 20k years ago. we have legit no clue how different life, nature and humans were back then. they couldve had supernatural skills, be giants, be free from slavery and jews...we have no clue. left only to speculate what a wonderful time it must have been.
power plants designed to withstand pole shifts and coronal mass ejections. there are even signs of water erosion near the top. giant pyramids for a giant flood.
