If you ever feel like archaeological mysteries are impossible to solve without positing aliens, just remember that archaeologists ONLY JUST NOW realised that wet sand is easier to drag stuff along on than dry sand… and that this probably means Egyptian images showing people pouring water from vases in front of stone blocks as they were pulled are probably actually depicting the way those stones were pulled, not some religious ritual of “blessing the rocks”.
FYI in academia, “probably had religious significance” means “I haven’t got a clue what this is for”.
People who aren’t academics, but who have knowledge of things like spinning fibre, knitting, carving, smithing, building, hairdressing etc, keep on astounding academia by having insights into stuff they thought was a mystery.
