Yes they do. But it is rather hidden. What is it? The Bible started around 1,500 BC. And over the years, it has increased in popularity until it is the best seller today, more than double the second one.
So, use your math to determine the odds for the popularity of the Bible, especially considering that other ancient writings have almost zero popularity these days.
Btw, that's just the tip of it.

That is not a divine digital signature. The scriptures need to be signed with a cryptographic signature. Some book has to be the best seller. That does not mean anything at all. You cannot go to the New York Times Best Sellers and pick a random book there and say it is from God.
