Just out of curiosity, given that it is almost impossible to verify whether any details of any stories about him are accurate with the possible exception of his being the brother of James, what difference does it really make whether there was one or more persons named "Jesus" if the bulk of what has been said about him rather obviously falls in the realm of metaphorical fiction?
Scholars are able to, with relative reliability, what Jesus would have done and even said in part. The process is the same used with various other historical figures who have also had mythical ideas attached to them.
However, the real importance lies in him being the founder of a movement that would eventually become Christianity. And since Christianity has had such a major impact on western history, Jesus has a great importance. Because of this importance, it does matter what we can actually know about him. And as research progresses, there is quite a bit that is being found out about Jesus with relative certainty.
In other words, if there was an historical person who was gradually mythologized into God, who cares? Fundamentalists will adamantly reject the suggestion that Jesus is anything other that what is literally described in the canonical Gospels - so they don't care. Aside from the need for this sort of belief-based faith, it's otherwise a relatively minor detail given how little we will ever be able to know about him.
Fundamentalists are a dying breed though. Religious people are becoming more and more liberal (especially in western societies). When one looks at book sales on the subject, or even the viewership of documentaries on the subject, one will find that many people are interested in the subject, even though modern critical scholarship does strip away the mythologized aspect of Jesus.
This is done for many of the same reasons we do it with any historical figure. Both Alexander the Great and Augustus were mythologized into gods. Yet, through research, those ideas are stripped away, and we get to see who those people were (as best as one can). It is done because they are important people in history, and knowing more about them reveals more about our history.
It's a relatively close call as to whether there is evidence of a particular historical figure named "Jesus" that was the inspiration for all of what became Christianity. But even if there was, from the standpoint of historical methodology, there's almost nothing we can really say about this person, what he taught or what he did. As an historian, the various movements that claimed and been inspired by these stories is almost infinitely more important than the historical person (if there was one) and the events of his life that, no matter how you slice it, are almost entirely lost to history.
I wouldn't go as far as to say that the events of his life are almost entirely lost to history. We can know various things about Jesus based on him being a male Jew, living in Palestine (more specifically Galilee), in the first century. We can know various things about him based on his relationship with John the Baptist. We can know various things about him based on the Gospel accounts when they are critically viewed.
Historical methodology can tell us quite a bit about Jesus. Now, what we can know about Jesus may not be able to be labeled 100% accurate. There is some guesswork, and most things can not be said for complete certain. However, that is true with many historical figures.
