Genetics demonstrate a distinctive Jewish-Portuguese heritage, especially in central Portugal, and the explanation can be given through an interdisciplinary analysis, involving geophysics, language, and economics. The text of the Bible (and the parallel existence of the Atlantis concept) can be put into meaning thanks to the strict application of natural justice concepts and of a basic hypothesis on a cattle herding economy that involved high degrees of inequality (caste-like), the victims finding justice in a cosmic fireball event that destroyed the nobility, triggered as well volcanic eruptions, and pushed them out, with a tsunami, as they had climbed on pumice stones. Because of the high natural radioactivity involved, from the fireballs and volcanic fallout, and of salt in the sea, memories were pretty much erased and the event reconstituted only simplistically.
