Interesting. This would make sense, especially after Ben told Karl that not everyone on the island should know about the Temple. I was at first thinking that the Temple was left from some of the early inhabitants of the island, a theory I'm sure this thread has already discussed. Do we know if any of the "others" have been off the island since the sub exploded? If so, that would help prove that Ben has another means off the island that not everyone knows about. The Temple would house some sort of device to get them where they need to go. Another sub? Or something a little more Star Trek?
