Was the EKUR that was built as a landing beacon powered by water?

Was water used to power the great pyramid? very interesting video on how part of the pyramid was a giant water pump.. Was this water used to power the pyramid somehow? why would they need to pump up the water if the Nile is just next to it? or is it built next to the water for a reason? Who would have had the knowledge to build such a huge machine if not the Anunnaki? Remember that according to ancient text Mr Siitchin said they were used as landing beacons for the incoming spacecraft. I guess these landing beacons would have needed to be powered somehow... Was a water turbine style generator used? So interesting. Let me know what you think.​
