Sorry, but Scripture says different. There is NO indication in the Bible that the grant of the keys was to anyone other than Peter. The "power to bind and loose" WAS given (later) to the other Apostles, and the Church has always taught that that authority continues in the authority of the Pope, and to a more limited extent, to bishops and priests.
No wonder you are confused; you don't even know what the "keys" were. You don't recognize how the kingdom has come to Earth, nor to whom it has come.
