Actually, it is unlikely that childhood stories were circulating around. Our earliest sources do not have really any childhood stories. And really, when looking at ancient figures, childhood stories were not common. They were not deemed important for the most part.Perhaps but why find any of the other stories of Jesus credible when dealing with the miracles. The popular opinion of Jesus was he could do miracles? Why not at childhood? It is likely childhood stories were also being circulated around. What makes the infancy of jesus gospel less credible than gospel of matthew for example other than mere popularity since we don't really know of a historical jesus without gospels?
As for the credibility of the miracles in the Bible, who said they were? I didn't. Yes, the popular opinion was that Jesus could do miracles; however, that not mean he could. It just means that people thought he could. This is exactly the same with modern day miracle workers. People believe they can do miracles, but that is only their perspective.
What makes the canonical Gospels more credible than the infancy Gospel? One, they are earlier. The infancy Gospel is of a late date. Second, the information in the infancy Gospel are not multiply attested to. Third, there is little reason to assume that people would have recorded his early life in the first place. There are quite a few reasons. It's late date is a major one though.
