That reminds me of the time I found myself traveling in Egypt with a tour group who thought they were all reincarnated ancient Egyptians, who in turn had been reincarnated Atlanteans. One of them remarked that there wasn't any evidence of the stonecutting the Egyptians were supposed to have done. And I looked around me at a landscape that was basically nothing but sand and rocks of various sizes, and thought, "Huh? What are you looking for?"
On another occasion we were looking at a long flight of steps carved in the side of a cliff, leading up to what we were told was a crypt. One person said, "I'd hate to have been a pallbearer in those days," to which another replied, perfectly seriously, "Oh, it wasn't a problem because they had the secret of levitation." And I just thought, "WHAT DID THEY NEED THE STEPS FOR THEN???" Sometimes people just don't think things through.
