I was thinking about this thing earlier today. Many people would argue that their particular Holy Book is better than the others because it produces better results, or espouses better principle etc. However, such things as that are incredibly subjective. In all objective ways these books are the same.
They were written down originally by men, they were copied over the centuries by men, they were translated by men, and it is up to men to interpret them, and they are so long and unclear that they are interpreted many different ways by many different people.
If an almighty God truly wanted to make his word stand out from other false works it wouldn't be that hard to provide objective evidence that would convince even the biggest skeptic that one particular Holy Book is different.
They could have made it a book that requires no translation, anyone who picked it up could read exactly what the Creator intended for them to read without any miscommunication caused by copyists or translators. The creator could have also included his Word coded into the human genome, or perhaps written clearly in the stars.
Such things as that truly would provided unimpeachable evidence of such a books divine origins. Much more so than a bunch of prophecies that are either vague, could very easily have been written down after they happened, or could have been "fulfilled" in a fictitious account that never happened. (Especially when the prophecy in question wasn't identified as a prophecy about that subject when it was originally recorded.)
