If we believe history, which is becoming more and more of a skeptics allusive magic trick, the Minoan society, a highly advanced peaceful society, was wiped out by the Myceneans’ because they didn’t like them. The Galatians from the Bible disappeared from existence because the Romans – didn’t like them. The Aztecs disappeared – and no ‘expert historian’ knows why. The Anasazi disappeared – the civilization on Easter Island gone – Mayans gone – and despite these civilizations being advanced some reaching into 1400 AD – there is no explanation. Only guesses.
