I was keen to read the "many compelling reasons" especially from the holder of the highest standard of proof on the planet.
So far I have
1. Col H Vyse was a fraud and he didn't find any AE writing he faked it all,
the original G1 only went to the approx. 50th level and KC and RC's were open to the breeze,
maybe there is a secret passage to RC's and the original builders anticipated renovation and left lots of blocks in place to seal it off much later!
2. The boat pits and boats was not contemporary with build and some nutter called Djedefre made them later
3. The world hasn't found the tools, they didn't have wheels, pulleys or foot operated potting wheels, so they couldn't have done it coz they were only stinky footed religious bumpkins.
4. RCD is completely flawed and it never ever works because it doesn't pass the bird poop in a bucket in a windstorm test.
5. The whole of Egypt had hundreds and hundreds of Co2 geysers sprouting water to in some cases 150m in the air but the lost civilization had built water mains to turn them off after use! The stinky feet AE didn't understand ramps and thought they were seeing natural mountains.
Have I missed any?
