"It is the opinion of the author of World Top Secret: Our Earth Is Hollow! that the Great High Priest over all the land of Inner Earth is King David, and sits on the legitimate throne of David, a direct descendant of David, who was the founder of the ancient nation of Israel in Palestine, from which the Lost Ten Tribes migrated to the North Countries in about 687 B.C."

These artic "voyagers" will be just as gullable as most of rest the Looney Left...you know, the people who paid to see Mikhael Moore movies.
