I have two information related to this post. The second picture you posted correspond to a carving I discovered with Google Earth on a mountain called Isabela de Torres in Puerto plata Dominican Republic.
I read a book about inner earth that states that underground under Aegean Sea exist a Library that contains books that were rescued from the Library of Alexandria and there are underground civilizations that protect and cherish the books and information. The name Portobelo came in my mind. People live extremely long lives there 4500 or 45000 years I do not remember exactly. They communicate to each other from other underground cities, have computers that use quartz that record the information. I do not know if this is related to the DUMBs cleaned that connected Vatican and Middle East where they have found manuscripts or is another layer or underground space.
