There is another way of interpreting what you offer...the Milky Way Galaxy viewed when it is upright from the horizon. You end up with a celestial river crossing from the southern hemisphere to the northern, from below the horizon to above, and Orion and all his pals spread out in such a view which seemingly correspond to the Nile River and particular stars here and there. You can get the belt stars of Orion equating to the Giza pyramids from that...and extend out to Bauval's offering too about other pyramids in their locations.
Things don't have to go too far in what they equate to if we delve into celestial appearances first. That's the basis of the AE beliefs, yes?
