It matters not whether all the animals of the Egyptians died in the 5th, 6th, 10th or just in some of the plagues. It matters not if Paul Revere was the actual person who warned of the British invasion. The truth is that God redeemed the Hebrews from slavery. The truth is that the Americans won their liberty from the Crown. As the lore of George Washington as a boy who confesses to chopping down his father’s tree teaches, we love truth–the facts don’t matter that much.
The second possibility is one some faithful might find more plausible: not everybody gets to do miracles.
In the Jewish Scriptures, which make up the Old Testament of the Christians Bible, read through it and mark how many times miracles happen. Compared to how many times miracles happen in the New Testament and you will see that they barely happen at all. In fact, generations pass before people see a prophet or witness a miracle in Old Testament times.
In the New Testament times, even among the Apostles, it is still rare. Sometimes there are reports of miracles happening left and right, but other times they don’t.
Why can’t everyone produce the same miracles whenever and wherever they wish? The Apostle Paul explained:
To each individual the manifestation of the Spirit is given for some benefit. To one is given through the Spirit the expression of wisdom…to another faith by the same Spirit; to another gifts of healing by the one Spirit; to another mighty deeds; to another prophecy…But one and the same Spirit produces all of these, distributing them individually to each person as he wishes.
He goes on to explain that the Christian church is like one body with many parts, some have gifts to do miracles, others do not. Being a pope is no guarantee you receive a gift to walk on water. God can give such a miraculous ability to anyone God wishes.–1 Cor 12.4-31.
Of course, it may be a combination of something in between: the miracles reported have some historicity to them, but the historicity is not the importance. The truth of the matter is something beyond the “fact” of the miracle. Is it that animals died by hail and fire? Is the fact of that matter more important than the truth of what happened in those events? Is the walking on water as important as who it is who walked on water and what happened when someone lost their faith in him? Is the fact or the truth the narrative is teaching us more important?
There may be great historical truth, down to the last detail in the narrative, but if you see only that, what good has that done for you?
