It's best to downplay whatever you think is there ; that way you are not disappointed if it becomes a nothing burger.
Ancient records mention that there are two sphinxes guarding the Great Pyramid; so there is no great surprise that there may be another one.
The Secret Chamber void above the Grand Gallery in the Great Pyramid may answer the question as to what is most likely to be found under it.
Apparently, there is a French team that are designing and working on a small fly like camera drone which will be inserted into the one and half inch hole drilled so far and fly around remotely, taking pictures...................if it proves to be empty except for dust; then what is beneath the pyramid is more likely to be an unknown quantity beyond it's overt perceptual interpretation of large stone pillars descending downwards.
Basically, we are back to square one, albeit with added extra detail. ................WHY......??? WHAT......???......HOW ???................continues.

I am not surprised that Cleopatra had a hissy fit with Julius Caesar over the accidental burning of the Library of Alexandria ...............the historical records of millennia went up in smoke in a few hours,............... along with the answers ..........................to many questions.
