Wow, it all makes sense now!
Cameron's movie, "Titanic" was just a promo for his barf-bag documentary, "Atlantis & Menorah".
It's all connected.
Are we even certain that the Titanic was an actual ship that sank, and not a symbol of the sinking of Atlantis that's been forgotten, recovered, and misinterpreted during the over 920,000 hours that have passed since it supposedly happened? Consider the similarities with Plato's account: it was highly advanced, had wealthy powerful people dwelling on it, and it sank in the Atlantic Ocean. Also, numerous writers over the years have described Titanic as a floating city, and James Cameron has made documentaries about it. With all those similarities, it's a certainty that the Titanic is actually a distorted memory of Atlantis.
