I've explained this many times already in this forum and I invite you to examine my recent posts over the past 14 days or so.
The others you named are not credible for reasons I have stated.
In each case the behavior of the leaders was to make stuff up and change things on the fly to further their own glory, power and wealth. In other words, they were caught fibbing by their contemporaries.
The 66 carefully preserved documents from 44 separate authors over 2000+ years that have been gathered together in one library called the Bible never gained any of that from their testimony and in fact most of them died alone and destitute for failing to recant their accounts.
The Bible is not just one book it is a collection of all relevant documents that exist. So naturally there are no others outside that library since every effort was made to make it a complete collection.
On the other hand, the others you mention do have plenty of evidence of being unreliable.
Finally, the accounts we have did not just appear one day out of nowhere. Each author was known well in his generation and the works were valued and preserved down through the ages. No other historical document comes close to it's pedigree.
I agree that credibility is in the eye of the beholder and am only testifying that I found it credible.
I understand that there is a category of people who won't and a category of people who do.
