This theory stands upon the idea of T Pillars being raised with the technique of "compound angling of the T pillars" from being flat to their appointed way of being straight up vertically! The meaning of Pillar 43 at Gobekli Tepe, Turkey, is the loss of their creatures in extreme antiquity. The design of T Pillar 43 is mean't with all it's etching, imprints, are about their creatures being lost forever when their planet's surface was destroyed. So the raising of T Pillars seem to be incredibly sacred to them.
So much so they decided to bury then when they went back to mars. So the extremely interesting part is they seem to have outside creature memorial sculptures totally related to Gobekli Tepe in Turkey! Loaded with ideas behind their raising the pillars at Gobekli Tepe ! Absolutely incredible I think !
