ben said it isnt an islans so i guess your mate was near the mark.

I also came to the conclusion the island is an inter-dimensional alien craft. Let's look at the evidence.

1. The island moved and it moved by Ben rotating some kind of lever that lit up. So obviously a machine or sorts powered the move, if that is what it was.

2. The black smoke. It exhibits some form of intelligence, remember it showed Ecko his life history before it killed him. It is also a defense mechanism which appears to defend the craft or its inhabitants.

3. Jacob. Jacob is some sort of sentient life form that first talked to Ben and is now talking to Locke. No one can see Jacob. Perhaps a telepathic alien life form?

4. The Black Rock. How did an 18th century ship end up in the middle of a jungle? Maybe when the island/ship emerged from the depths or teleported underneath the Black Rock.

5. The electromagnet. A large electro magnet was responsible for shooting Oceanic flight 815 from the sky. It later blew up filling the sky with bright white light. An alien weapon? It's likely not an electromagnetic propulsion system since the ship/island later moved.

6. The Ghostwhisper. The show introduced a new character that can apparently talk to the dead. He already is aware of things on the island others aren't. Is he communicating with Jacob/alien telepathically?

7. This last one is not Lost evidence, but JJ Abrahams evidence. His latest projects include Cloverfield, where an alien monster baby falls from the sky to terrorize NY, Star Trek, no need to say more, and FOX's Fringe, which is said to be an updated version of the X-Files.

Finally, I do not think the "others" are aliens, at least not all of them. One appears to not be aging, showing up at Lockes birth, then again as Locke is a child, and then on the island as an other without having aged a day. So I could see him, but no one else. Most of the others are survivors from Darhma, the French expedition, plane crashes, etc...

The aliens scenario just play into Abrams. It explains most of the unanswered questions about the strange technologies and telepathic nature of the island.

Something just occured to me. Maybe its not just an alien ship that can travel interdimensionally...

I was researching my theory on other sites and someone brought up the test Locke received as a boy. If you remember the test was which one of these items is yours? The kid didn't know.

The others have been convinced that Locke is their savior. We see in the future he returns to the US to convince Jack and the rest to go back but is killed by someone.

What if the "other" that doesn't appear to be aging is traveling through time? He is returning to the past to find Locke hoping he can help them. Help them to do what, I don't know.

This would also explain why the other other showed up after Locke was paralized and informed him he would be going on a walkabout. He knew the future.

Nanobots, electromagnatism, telepathy, all things humans have yet to master but some day may.

So the island did move... but the question is not where, but when.

Could you say the word 'leader' any more in the first few paragraphs? Terribly written piece.

I think the island is the lost city of Atlantis. The Atlantians were supposed to be an advanced civilization and it could explain the weird markings in the cave and the technology, especially the black smoke. It could be some kind advance defense for the island and it's inhabitants. The "others" could be descendants or the actual Atlantians since it looks like they don't grow old. As for some of the passengers of flight 815 they may also be descendants of the lost civilization however the exact reason or purpose that they are on the island I'm not to sure of. Just speculation at this point.

I have contact with a writer who knows J.J. Abrams. He has told me that during the beginning of Lost, J. J. Abrams confided to him that the characters in Lost have, indeed landed on a spaceship. This is a reliable source, and I seriously doubt that this man would lie to me, but it is possible that Abrams has changed his mind since then.

I Still lean towards the idea that the island is some kind of go between with regards to life and the after life.

Reasons:

all of the oceanic six feel out of place in the real world kind of dead inside.

when micheal was about to be blown up; jacks' father said you can go now.

the sick are healed just as the bible says you shall be once you ascend to heaven. maybe this is the waiting room. maybe going back to civilazation is hell on earth.
