What organization has said that there is no historical connection to association football with any other game outside of Europe?
Association football in itself does not have a classical history. Notwithstanding any similarities to other ball games played around the world FIFA have recognised that no historical connection exists with any game played in antiquity outside Europe. The modern rules of association football are based on the mid-19th century efforts to standardise the widely varying forms of football played in the public schools of England. The history of football in England dates back to at least the eighth century AD.
