Wouldn't be sayin much lol

Very true lol.

The ruins on Venus predate humanity, I.E. The Vault of Glass and the Citadel, the Vex themselves didn't show up until the Collapse. There is a Grimoire card that comes from the Ishtar Academy that refers to a "vex platform" A.I., but this particular record is heavily implied to be a Vex studying a simulation of Humans studying a Vex. (Not making this up)
