Ok, re-reading it I am also put in a vague sense too. I meant to say the un-imaginable every now and then does occur, the limits we put on ourselves or others are based on the context we see the facts. So, as you state; the structures atop the plateau are essentially solutions or the AE answers to their quests. Knowing these structures are answers doesn't provide us with knowing the original questions because we only know part of the context they were formed in. Thus everyone works on probabilities to fill in the gaps, in my view the gaps become wider when hyper theories like ...the pyramids were water pumps... are built upon the loosely held-together theories most commonly accepted as having a higher probability. The only way you can change theory is by showing an irrefutable change in the overall context.
