The pursuit of knowledge only ends with death upon the horizon.

No, not necessarily. But I think one of the points of the game being that. Look at the wall paintings in the old Zu village, for example. The one depicting the three squareheads with fezzes (whom which can safely assume are the ghosts in the graveyard) going into the stargate are then caught in its destruction because they took this knowledge given by the Visitors for granted. Curiosity did kill the cat, you know.
Old Zu is from the past timeline. This is when they were enlightened with 2D, not 3D. At least, this was what I understood.
No, old Zu is where they were first introduced to 3D by the Visitors, and then all that jazz happened.
