The Question of the Greek New Testament

[Jenny A]

A lot of the Bible written after the Gospels and the Book of Acts was likely written in Ancient Greek because the people who were reading the letters of that time were in the Ancient Greek cities. Paul likely could speak Ancient Greek and Ancient Hebrew as well as Latin. I doubt he knew how to speak Aramaic, however.

The Gospels and Acts where written, AFTER Paul's letters, not before.   And by the time they were written there wasn't much of a Jewish Jesus sect left.  And they are written from a Gentile perspective in large part.  There's no reason to believe they weren't re written in Greek.

Paul's first language was probably Greek and at least according to acts he spoke Hebrew.  He spent time in Jerusalem though and may consequently have picked up some Aramaic.  Aramaic and Hebrew are related.  But as Greek was his first language and he was writing to Greek speakers, it would have been odd for him to write in anything but Greek.
