An image describing this text. El astronauta Neil Armstrong, shortly after his famous walk on the Moon, He traveled to the heart of the Amazon jungle to explore some Ecuadorian caves where he found metal sheets with inscriptions from a culture that has not yet been recorded.. It was a strange expedition, surrounded by military secrets, in which there was talk of an entrance to an unknown underground realm. The curious thing is that later the astronaut would say that this descent into the depths of the earth had been more amazing and mysterious than his journey through the cosmos.. It's almost always like this. Journeys inward are more revealing than journeys outward.
