Likewise l have thought of many scenarios to try and explain what we see today. It is like a game of chess with many permutations. These permutations can be reduced only when a thorough forensic examination of the structure is done, modern science and an multi disiplinary approach is required. Sadly it will not happen in my life time, Egyptology is clearly content with its exploration of the structure and its explanation of it, nothing new to see here, please move on.
l do feel that Egyptology has sort of painted itself into a corner, it might take a generation or two of new younger egyptologists to arrive before the necessary thorough exploration is done.
l am just an amateur and l doubt any egyptologist will read my work, though l am getting positive feedback from other disciplines and since l posted the paper, new evidence has emerged which will hopefully reduced the permutations we are faced with and l will include them in an update in my part 2.
