In talking about the language and math being translated and translatable, to what we have today from what the AEs had back then, it appears that we do have a certain grasp of what they intended. But this is not to say that they themselves knew what they were intending.
If we can readily identify that our efforts of translating their works can be fraught with basic interpretations rather than their deeper meanings, then the possibility of them having done the same things is real. In other words, we can never be sure that they understood let alone developed what they left behind.
A case in point: the casing of the Great Pyramid against the core stones of it. On the one hand, the alignment of the casing suggests a particular direction was being aimed for; while on the other hand, the core stones define a slightly different direction was being aimed for. They are slightly different, and yet that there is a difference is quite important.
In my own study of the pyramid, I found that there is a better association to arrangements when the casing is not included, and this makes me believe that their own deciphering of their intentions shows separate plans integrated together because they weren't entirely sure which was the better plan to use.
I do believe that there are two plans and possibly three that the pyramid is built from:
to identify very particular moments in time and show this in the architecture when an astronomical map is overlaid to the pyramid;
to make use of certain mathematical formulas tied into scientific parameters according to the substances used in the pyramid, and how these substances are positioned to interact as a whole...an example being a simple two stroke engine with its materials and chambers and fuel, and all that's needed is the spark plug to get the thing going.
a third plan takes into consideration the particulars of the person/s who initially used it, and the tale of Seth tricking Osiris into the perfectly constructed sarcophagus alludes to this.
Another good tale concerns Isis gathering up the 14 pieces of Osiris, without the genitals (making 15 pieces in total) and a series of rituals leading to the conception of Horus. If we look upon the pyramid as the instrument that enabled this wonder to occur, we can recreate the science theoretically, and see the clues left behind in the pyramid itself that this was the reason for its features. But again, that 'spark' is the thing that we cannot grasp or even allow ourselves to grasp, due to not being able to accept the separate plans of the pyramid working together...we can see one layer and not accept that there is another layer, or two layers, and so we all have separate theories rather than combining those theories into one operation of fantastical synergy.
Returning to the language and math again, we cannot be sure that the AEs were responsible for the construction of not just the Great pyramid but several other pyramids also. Their own efforts at recreation were very good, and their adoption of some of these pyramids does appear to be just that...the casing upon the pyramids alludes to this, due to the differences in orientation specifically in the Great Pyramid, but also Khafre's pyramid alludes to this because of the two types of core stones showing: an inner layer very nicely shaped; an outer layer quite crude; with a skin of casing over the top. Anyway...just saying.
