History would seriously disagree with you.
The Catholic Church is the original (and
only) Church founded by Jesus Christ. St. Ignatius of Antioch, the bishop of Antioch ordained by St. Peter, the Apostle, was captured by the Romans. While they were transporting him to be martyred for the faith, he wrote a letter to the Smyrnaeans around 107-110 A.D., referring to the "Catholic Church," not in such a manner as if he were coining the term, but in such a manner in which he fully expected the Smyrnaeans to understand what he was talking about.
It says in paragraph 8, "Where the bishop is present, there let the congregation gather, just as where Jesus Christ is, there is the Catholic Church."

The Orthodox broke off in 1154 A.D. See the background history on this here:
And Protetantism didn't begin until the 16th century, started by an ex-Catholic monk, Martin Luther, on his own, self-appointed authority. And it has continually splintered ever since, into literally thousands of man-made, doctrinally contradicting denominations, all based on individual personal interpretation of Scripture, which St. Peter warns against in 2 Peter 1:20-21.
BTW, the term "Roman" Catholic Church is not the official name of Christ's Church. It is simply the Catholic Church. The "Roman" part was a pejorative used by Anglicans to attack the Catholic Church when they broke off because the Pope wouldn't sanction King Henry VIIIth's divorce and remarriage.
