Of course the Egyptians knew it, I think. The Egyptians were very much interested in ‘life after death’, but not in the sense that many assume. Could it be that they were interested in ‘life after death’ in this very life-time?
The life after death of rebirth, the life after the death of the small ‘self’. This is the death of the ego-mind, or at least the death of the dominance of the ego-mind and the arising or re-birth of our sense of ‘essence’.
It’s that space that is difficult to put in words accurately, the observer consciousness, the sense of presence, wakefulness, alive, attentive to the inner experiences of feelings, body and mind, while also perched at the sense doors.
It may well be, that the great pyramids weren’t actually created to be burial chambers, but more a form of retreat hut where the privileged, or ‘initiated’, we able to go and experience this art of rebirthing. The energetic set up of the pyramids designed to give the greatest efficiency to this process.
So they seemed to know, if this video is correct, that the answers lay behind the number 9, which encodes this very teaching of rebirthing!
