Hazel,
As always, you never cease to amaze me. You mentioned "Zion," as one of the
points. In the movie "Matrix," one of the two brothers on the ship, whom
refer to themselves as the real humans, say that they come from "Zion," which
is near the core of the earth, where it is still warm.

PS Any HE's who have not seen it, should check this movie out.
