Robert Bauval once said something that has, in it's elegant simplicity, stuck with me. He said that he thought the pyramids were there to "make us think."
WHAT IF all the tools, pots, food, water, etc., we're put in place more to hint at the function of the place where they were put, rather than with any real expectation that they would ever be very useful. More as a marketing angle to sell us on the IDEA of the place, as a hedge against some future time when the people of the earth might once again be wondering.
Just a thought ...
Ronald Popeil, inventor of the hugely successful Pocket Fisherman, a collapsible and compact all-in-one rod / reel / tackle box combo product, was once approached by a critic who complained that Popeil's invention did not work very well, to which Popeil replied that the Pocket Fisherman was not for fishing but for GIVING.
All Best Wishes,
