US Expedition to an Inner Earth Kingdom

This intriguing theory is actually starting to make sense to me. The liars that run this world push an imaginary infinite universe when new worlds could be right under our feet. Vast underground tunnel networks have been found worldwide. There are so many legends about this, some claiming an entrance to the inner earth at the North Pole, as in Admiral Byrd's diary. The fact the earth is a level plane doesn't rule out an inner earth, the Tartarus of the ancient Greeks.
