I’m struggling to find anything that confirms Peter was a real person.
If you just swallow the sacred history of the RCC and run with ‘maybe the bible is true’ but that works with loads of religions.
You surely can’t be reading the Book of Acts as history?
He pops up in briefly in Marcion’s first New Testament in around 140CE and then becomes some kinda patriarch figure in the later 27 book Catholic New Testament and via St Irenaeus.
Scripture is awesome but for the love of God don’t be reading the Catholic 27 book NT’s like they are history textbooks.
We have no idea who St Paul was or what he wrote either, it’s fine.
