I need some help

The guy teaching my History of Christianity class told everyone that there wasn’t a pope in the early Church, and minimized the role of the bishops. I knew it was wrong, but I couldn’t challenge him because I have no evidence to support it. Does anyone know of any documents from the time of the Apostles, or shortly after, that support the papacy and the bishops?

Thanks

God Bless,
