It was hidden in plain sight for millennia. Behind the Sphinx’s right ear is a hole with a blocking stone in place. It is the entrance to a secret chamber.
Some of you already heard the story of Kipriyanovich Boriska, the very intelligent boy from Russia (now adult) that at the age on 1 year he was reading newspapers. From a young age he claimed that he remember his past life on planet Mars, planet that had not a good fate.
Boriska gave information about the Sphinx and the secret chamber behind its ear, telling that life on Earth will change irrevocable once the great Sphinx is unlocked, using a complex mechanism behind one of its ear. It looks like Boriska disappeared, he was not seen anymore since then. It is strange, because he claimed that he is a reincarnated soldier , placed here on Earth to avert the same destructive fate as Mars, telling that many people like his exist on Earth, and they are called “Indigo children”.
Graham Hancock is another figure, who has publicly stated that there are many mysteries surrounding the sphinx, that a time capsule is hidden within the sphinx.
