An "ancient alien library" is buried underneath the Great Sphinx.
Alien secrets could be hidden beneath the Great Sphinx
Experts are convinced that the iconic statue in Egypt could be home to knowledge that has been left behind by extraterrestrials.
American clairvoyant Edgar Cayce claimed in the 1930s that survivors from the lost city of Atlantis had built the infamous Hall of Records to preserve their history but there are concerns that it may have been destroyed by centuries of flooding.
NubTV expert Mark Christopher Lee says that more secrets about the Sphinx will be revealed once humanity learns more about UFOs.
He said: "There is said to be an ancient library below the Sphinx which may hold the answers and is reputed to be a lot older than mainstream archaeologists say it is.
"Did aliens help build these structures or are we dealing with a more sophisticated society than we thought? I do think we are now realising that history as we know it is not true.
"Maybe with UFO disclosure we may get closer to understanding our true origins."
