How could you know the bible is true? [Spirituality & Religion]

i'm a Witness so i know he is Real , but for most they don't really knowm , and the only proof i really have is my stories of truth , thats why the Bible has these too , because i can't share my experiences with God and how they really were becausee i'm not God , and so there's only my stories of truth to share which is a drag for me too to have such little proof at all
