The proofs of what you say are glaringly absent.
I would bet a Hershey’s chocolate that Paul spoke in Greek when he was addressing Greeks, so the foolishness of claiming the Apostles didn’t speak Greek is, well, telling. Paul was smart enough to read the Greek inscriptions on the idol pedestals and focused his audience’s attention on the one dedicated to the ‘unknown God’. He would have done that in Greek, considering his audience.
