Museum of engraved stones

Dr. Javier Cabrera opened this museum containing pebbles and other engraved stones, representing dinosaur hunting scenes, organ transplants, erotic scenes, etc. He deduced a theory of aliens who had come to earth to teach humans techniques and other things. However, most archaeologists today claim that these stones were carved by contemporary artists and not beings from space; however, the quality and beauty of the pieces is no less important.
