Since Catholicism lists Peter as the first Pope?

All of the apostles held the keys of the kingdom but it was Peter who was called to preside over the entire church.

Peter was NEVER the Bishop of Roma

therefore he could never have been the poope

none of the people you mention ( or jesus) ever existed , paul invented all his stories , the first pope was in the 4th century , there was no messiah nor even a need for one

Don't be silly, the Roman Catholic Church will tell you any lie to get you to serve them.

Yes, they answered to Peter.

Jesus healed Peter's mother-in-law, so he was married?

Catholics recognize 266 popes from Peter through Francis.

The ones who were not martyred did follow his lead. We know this from the letters of Polycarp who was a disciple of John. We also know this by letters from Clement who was a disciple of Peter. You say "they established their own churches" but this is not the case. We know this because we have letters from the bishops of these churches that succeeded the Apostles who established them. In all of these letters we see a homogeneous church, in which permissions and advice was inquired by whomever was the bishop of Rome at the time. You see, there is proof of this.

The same as today each bishop governs his own diocese but under the control of the pope(Vatican).

The apostles you listed all recognized peter as the the first pope.

Good point. And Paul actually rebuked Peter in Galatians chapter 2 as being wrong on something he did. Plus, Peter was married (Jesus healed Peter's mother in law), and Peter said "silver and gold have I none". :)
