In which history book does it say that Saudi Arabia is the birthplace of civilisation and muslims had anything to do with it ? The OP was talking about advanced muslim civilisations when he obviously meant Persia, who were Zoroastrians. I use the word Persia to mean Iran / Iraq / Syria / Turkey and parts of central asia who were fairly advanced in the past and some are still advanced to this day. Muslims did not invent and make anything. Even the so called islamic golden age was a direct result of brain drain from Persia. Arab muslims and Persian muslims are wildly different. Iran has long maintained their pre-islamic language and culture. It was because of Iran's resistance to becoming Arab that any golden age was at all possible. This rivalry persists to this day in the islamic world as Saudi Arabia vs Iran vs Turkey. https://en.wikipedia.org/wiki/Islamization_of_Iran https://en.wikipedia.org/wiki/Islamization_of_Iran
