Authorship of canonical gospels
I got a question regarding who authored the gospels in the bible. The traditional interpretation is that they are written by the apostles (or whatever they were, if they actually existed) with the names we know today. This I don't trust as far as I can throw it, mainly because the bible contains all sorts of embarrassing errors and most of the traditions derived from it are plain ridiculous.
I realize that such a blanket statement isn't an argument. Would I be correct when I think the reason for dismissing the traditional interpretation is that the gospels are written too late in time to be from an actual person around Jesus (if he existed) or the apostles? That combined with that references to the gospels as written by Matthew, Mark, Luke and John don't appear until the latter half of the second century, which is two generations at least after they were written? Is this close to why, and/or am I missing something?
I think that if a reference to the gospels (other than the fact that they borrow from each other) which doesn't refer to the traditional names could be found, that would be the kind of smoking gun needed to kill the traditional view. Maybe such a thing exists?
I apologize if this is trivial or covered elsewhere on the forums. If so, I'd appreciate a like to where that would be.
