The Incas had their alcoholic beverage and never had contacts with Islam. China had their rice alcoholic beverage, pre-Islamic ancient Egypt had beers already. "Chinese alcohol predates recorded history. Dried residue extracted from 9,000-year-old pottery implies that early beers were already being consumed by the neolithic peoples in the area of modern China. Made from rice, honey, grapes, and hawthorn, it seems to have been produced similarly to that of Mesopotamia and Ancient Egypt." https://en.wikipedia.org/wiki/Chinese_alcoholic_beverages#Ancient_China https://en.wikipedia.org/wiki/Chinese_alcoholic_beverages#An.... You're aware that alcohol is nothing more than letting something rot for a while by mistake ie fermentation (rice, grapes, corn etc)? Algebra was invented by Greeks and Egyptians, same for algorithm (Euclyd anyone?) etc. The Islamic world built on top of that and helped improved it and that was awesome, but they did not invent any of these fields. I'm from Muslim Syrian origin myself so it's not like I wouldn't enjoy my ancestors taking all the credits for these fields but this is simply not true.
