Honestly I can't think of a single thing.
Nobody knows who wrote it, with any degree of certainty. No names of the original authors, nobody knows who was on the Council of Trent , Council of Nicea Etc.
It's obviously been redacted , has incomplete information and has gaps in its narratives. Side-by-side variations are noted in each version of the Bible that exist today to substantiate that is indeed the case.
The Bible clearly is not a divinely inspired collection of books either , evidenced by Christianity's vast and varied amount of denominations and sects, who, to this day remain visibly at odds with ongoing issues over interpretation and meaning, making it clear there's no evidence of any type of guiding hand at play to indicate it now or was ever divinely inspired to begin with at its inception.
There's no real support or proofs to the notion of divine harmonization between one author with another throughout the Testaments over significant periods of time to substantiate any type of harmony exists because each subsequent book could be "harmonized" with each proceeding book by simply reading what each proceeding book said and conveniently changing the subsequent book to "fit" each narrative to uphold the claim that the subsequent authors did not know what the preceding authors wrote making such alleged harmony between books a divine proof a Biblical accuracy and credibility.
Oral tradition is actually worthless. If it wasn't, it could have been used and demonstrated today as a living testament of reliability and accuracy but it isn't for a reason. Obvious reasons.
Hence the requirement for writing something down , and we've seen how effective that can be.
Why would anybody be willing to think the Bible is for one reason or another a proper foundation to base an entire religion on and in cases, people's own lives to point of believability that it would trump logic and science?
