No... no, they are not. What you are saying simply cannot be proven.
Knowing this caused John Henry Newman to convert to Catholicism, and it nearly caused me to convert.
Funny thing how that could work - It is the history that causes me to avoid the Roman church like the plague. There is no_way_ever, because I know history.
Me neither! Not only that, but I know what Scripture says and it was when I read it for myself (i.e., John 10:27-30) that the Holy Spirit opened my eyes and my heart to understand the Gospel of grace and to reject the false religion I was raised under. All I have learned since then only confirms I did the right thing and am on that narrow path that leads to eternal life.
