What intrigues me is the stone with the supposed circles or spirals on it. This stone is not shaped at all (perhaps flattened, but not squared or so), so it doesn't fit in with the rest of the story. We still have way too little information, but it still looks to me as if only the positive info is given and highlighted, and everything that disagrees with the idea of a pyramid is hidden (in text, not in reality).
