Documentary: Unexplained Conspiracies Of The VATICAN

The Resurrection is a sculpture located at the Vatican that depicts the resurrection of Jesus, but some have called it the "Demonic Idol in the Vatican" due to its eerie appearance resembling a demonic serpent rising from the depths of hell. The sculpture was installed in 1977 by sculptor Pericay Fazzini and is a whopping 66 ft long and 23 ft tall. The hall in which it is located, the Audience Hall of Paul VI, was designed by architect and engineer Pierre Luigi Nervi in 1964 and has been associated with other snake imagery. The hall is where the pope holds his weekly audience whenever he can't make an appearance outside at St. Peter's Square due to weather.

The Vatican's secret archive is said to hold over 17 million pages of documents, and some conspiracy theorists believe that proof of extraterrestrial life is hidden somewhere within it. Cardinal Conrado Balduchi of the Vatican once stated that meetings with aliens should not be seen as demonic and that instead they deserve to be carefully studied. He also referred to a paragraph in the New Testament in which St. Paul refers to Jesus Christ as king of the universe, which could imply that Jesus is the king of all things in the universe, including aliens.

The Vatican secret archive has roughly 53 miles of shelving filled with treasures and ancient texts that very few have ever had the privilege of seeing. While the existence of the archive is real, nobody really knows what's hiding inside and even though the Vatican has tried to remove the mystery around their archive by changing the name from secret archive to Apostolic archive.
