raymond frantz : By the way Eusebius is not the only one of that period to write about the Christian Exodus.
You are right. Epiphanius also discusses the flight to Pella. Three times in fact. Twice in the Panarion and also in his treatise On Weights and Measures. But Epiphanius wrote in the second half of the fourth century which was after Eusebius wrote his Ecclesiastical History.
raymond frantz : I'd rather believe Eusebius who lived 200 years after the events rather than a Jewish "historian" who lived 2000 years later ...
The point isn't so much that Eusebius wrote about Pella 200 years after the alleged event, but that none of the prolific writers amongst the ante-Nicene fathers mentioned it before him. No-one, Christian, Jewish or pagan, mentioned it for 200 years.
