Muslims were really creative people back in the day (maybe they are now but I have no idea) so they created lots of things, but their creations were stolen because they didn't share the creations, they created things like coaches, clothes for animals, so if you look it up on the internet it would probably say that Americans made that or something. I know that because I have a history club after my school and they tell me loads of some intersting things people wouldn't know.
