Distraction from what Coma?
Someone's theory? There is no need to cause a distraction from that.
They will never prove that Christ did not exist. "Jesus"... as in the various faces and images that religion has given to him... perhaps. But the actual man, who is the Christ? No.
Scholars (and some not-so-scholarly scholars) may come up with theories, and explanations, and likelihoods, etc. Same as people before them came up with their theories about the pagan christ, and copycat myths (that are also baseless).
It is never the facts that are the problem... (or the truth)... but rather people's interpretations of those facts and/or truths. Be those people scholars or not-so-scholarly scholars... or simple laymen.
Peace,
