Know?
Try this:
There is no objective evidence that the bible’s origins are anything but human. Furthermore it is demonstrably errant, morally questionable by any objective human standard, inconsistent throughout, outright contradictory in parts, and bears all the hallmarks of human origins, which mirror the superstition, ignorance and prejudice of the archaic patriarchal male dominated societies from which it first emerged.
Don’t generalise, its sloppy, and don’t make sweeping claims to knowledge that you don’t have.
Avoid phrases like I/we know, or that include words like proven or proved.
Use the words evidence, and objective, cite specific flaws in the bible that contradict the unevidenced claim its origins are a divine omniscient omnipotent deity.
Do the leg work, and put in the effort. Let theists make sweeping unevidenced claims they can’t substantiate.
