While personally I'm quite open to the true purpose of the Giza Pyramids; imo the tomb hypothosis is still just that, it's unproven by all possible definitions; the RVT will also need more proof, which isn't to my mind going to be easy to find.
However, I have one small question to start with, and apologies if it has been answered elsewhere:-
If the Gizamids are Recovery vaults, then why the incredibly complex and intricate design of the Grt Pyramid's interior?
Surely several medium sized regular shaped (sealed) rooms would not just suffice, but would be much more practical, and all that was necessary. The shafts, I understand are intended to point to stars in the hypothosis, but why the rest of the design?
