This proves nothing, other than the fact that there will always be critics against anything - including art.

The question of the origin of the New Testament includes yet another literary problem, concerning the Gospels especially.
Are these writings independent of one another? If one of the Evangelists did utilize the work of his predecessors how are we to suppose it happened? Was it Matthew who used Mark or vice versa? After thirty years of constant study, the question has been answered only by conjectures. Amongst these must be included the documentary theory itself, even in the form in which it is now commonly admitted, that of the "two sources".
The starting-point of this theory, namely the priority of Mark and the use made of him by Matthew and Luke, although it has become a dogma in criticism for many, cannot be said to be more than a hypothesis. However disconcerting this may be, it is none the less
true. None of the proposed solutions has been approved of by all scholars who are really competent in the matter, because all these solutions, while answering some of the difficulties, leave almost as many unanswered. If then we must be content with hypothesis, we ought at least to prefer the most satisfactory. The analysis of the text seems to agree fairly well with the hypothesis of two sources--Mark and Q. (i.e. Quelle, the non-Marcan document); but a conservative critic will adopt it only in so far as it is not incompatible with such data of tradition concerning the origin of the Gospels as are certain or worthy of respect.

Whatever these men conclude, it does not prove anything - unless they be gods, and even then, they won't be able to prove that.
To get the truth most anything. It usually has to speak for itself. The Bible does that. The evidence speaks for itself.
The harmony, practical value, honesty, and accuracy within gives evidence that it is authentic, and divinely inspired,
There will alway be critics.
The Bible outlives them. It has won all vicious attacks against it. It stands strong in the face of insurmountable odd - and still stands on top.
...and the people who live by it - equally undefeated.
The proof is in the pudding, and guess who's doing the eating?
