Either the bible is the creation mythos of a stone age civilization topped up with some books from the iron age (and thus the scribes could have no idea about the future trajectory of society) or it's completely inconsequential to the core message of the bible: you are god's creation, and your eternal soul can be saved if you acknowledge jesus as your savior and accept redemption.

Both are compatible: you still have a soul after LLMs were made after all (if you believe that sort of thing)
