My Theory of Everything

Ok, so maybe not the theory of everything. Maybe the theory of a lot of stuff.

Jack is Jacob.

Whatever Jack does this week to either cause/prevent the "Incident" causes him to become caught in a pocket of "non-time" whereby he is both there and not there. Jack knows enough island lore to be able to appear like he is predicting/directing the future and therefore somewhat God-like.

Jack being Jacob explains why both Christian Sheppard and Claire are with him. Hurley's relationship with Jack explains why Hurley can see the cabin.

Locke is the only one who can actually "hear" Jacob and the last time Jacob spoke, he said "help me". Helping Jacob/Jack encompasses releasing him from whatever non-time purgatory he has occupied; it also will compromise the special qualities of the island.

The Dharma hippies, the Others, the Widmore mercenaries, Ben, Richard, Widmore, Ellie, etc., are all only out to explout the island, which is why Ben and Richard see Locke as a threat. Locke is the only one who has the pure interests of the island at heart. And Locke also knows that killing Jacob also releases Jack fromn the purgatory and destroys the special qualities of the island all at the same time.

The smoke monster is the gray ash, which is metallic and can be manipulated by Jacob who controls the electro magnetic properties of the island.

By the way, I'm about as sure of all of this as I was about Hurley being the occupant of the coffin. Which I was pretty damn sure of. But wrong.
