“Greek was the translation from the Aramaic the language that Jesus and Simon spoke”
No.
The Holy Spirit inspired the NT in Greek. The words are His and they are Greek words.
You weren't there and you don't know.
Eusebius quotes Papias, who lived, oh 1900 years closer to the events in question than you or I do and no doubt knew people who knew the Apostles personally, as saying that Matthew was written (a) for Jewish converts; (b) in Jerusalem; and (c) in Hebrew.
I don't see what in the Bible (or elsewhere) supports that proposition. It seems like an article of faith.
Also, Paul seems to refer to Peter as "Cephas."
"Petra" πέτρα is feminine. "Petros" Πέτρος is masculine. It would be at least awkward to call a guy Petra. It would be one thing to say that so-and-so is a πέτρα. It would be another to NAME him Πέτρα.
