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?
For anyone really interested in the pyramids that hasn’t seen this yet, I highly suggest it. The guy goes into great depth and detail as to how basically all the pyramids have different uses in chemical production and even weather modification.
The weather modification part sounds crazy but just watch it, you won’t be disappointed. It’s a longer podcast but if you just watch the first half you’ll get the gist.
