You're comparing thinking ahead as it is for burning oil with a monument that is still baffling engineers and arguing that the human mind doesn't have the equal ingenuity to observe small, minute changes in heavenly thing despite the baffling engineering feats, and like the link to the hydropulse generator you still don't say why they would rely on tidal forces from Sirius when obviously they could have used the Ur Nile which is naturally elevated.

People have been processing ideas in aeons as is evident by the Kings List . That still doesn't explain how they harnessed energy up to 7000 years ago but there's no trace of what it was used for, or who used it. Some estimates are that they were built 50k years ago, but if you watch the documentary about the map math you'd have to consider that they are even older, and the older they are the harder it is to claim that it wasn't foresight which comes from the wisdom built on utmost precise observations, but, chance since the precision the encoded man holds is phenomenal.
