We have no ibndication other than that "it looks right" for almost anything at all concerning the pyramids and their builders. It "looks right" they were building tombs withramps. It "looks right" they were barefoot bumpkins who never changed.
If the premise is so unsupported as you claim then why not show the evidence where the builders said there was no plan at Giza. What! You can't. Of course not. We have almost no information whatsoever and the little that does exist is determined by Egyptology to be the mindless rantings of barefoot lunatics. Never mind that the builders spoke of the followers of Re' from the west who made the way of the twilight mount up. This is to be ignored despite the fact that twilight mounts up along the row of pyramids on the solstice because everything the builders said means nothing and only Egyptology knows anything about pyramids and as we all know "they mustta used ramps.".
Orthodoxy doesn't play well with others.
They aren't onlystuck in a rut they want to drag everyone else in with them.
