Jughead is not the incident by Chad

The most common idea I have seen reading all of the theories is that the detonation of jughead caused the incident and will somehow result in a reset. We don't even know that the bomb went off. The incident is radinzky drilling into the pocket of energy. WHH is true. Someone wrote that the result of the incident is that the hatch won't be built and that being the case 815 won't crash. But the reason the hatch exist the way it did with the button and the numbers being entered every 108 was because of the incident. The incident caused the hatch and the hatch caused the crash but the losties do not cause the incident.
The incident happened, they just happened to be there.

As far as Alt timelines and resets go, we have already saw it.
In "Further Instruction" Ep 3 of season 3, This is after desmond has turned the fail safe key. We see a flashback of JOhn LOcke. He becomes a part of a hippie, farming community. He picks up a young guy hitchhicking who turns out to be an undercover cop after this group becaus of weed. Lock brought him in so Mike and his wife, are upset at Locke and John says that he will take care of it. He takes the guy hunting in the woods and confronts the cop and points a gun at him. The cop says to JOhn that John is a good man a farmer not a killer.
Then John says "I'm not a farmer, I'm a hunter. Where was John a hunter? The Island! I think He experienced the same thing desmond experienced that we saw in flashes before your eyes.
There present consciousness is in their past bodies.

A few other things. The consensus is that MIB takes the form of dead bodies on the island, but what about Ben's mother and Hurly's friend from the psych hospital. Their dead bodies would not be on the island. And we saw Walt on the island when he was back in the real world. Don't really know what to make of that but not every one we see on the island is dead or has a dead body on the island.

AND in season one when Jack and Kate are on the beach and he says that he's ready to go to the caves and she says she doesn't want to be Eve. You can see four wheeler tracks in the sand.
WHAT DO YOU MAKE OF THAT
