If that were the case, then modus tollens is not the valid form of inference for such a premise. Which is what I've been trying to explain. I could, of course, be incorrect.
modus tollens is always valid with whatever A -> B is. It never is invalid. It may not produce a sound conclusion but it's always valid.
In the case of the verse there is two conditions,
If it's from other then God (sufficient condition)
Then they would have found there in much discrepancy (necessary condition).
Modus tollens makes muse of the necessary condition.
