When you are within a worldview your ability to deconstruct that worldview is severely hampered. You are impressed by things like 8 mormon witnesses because they support your worldview but you will subconsciously dismiss any number of witnesses for events that disagree with your internalised truth. This way of thinking is how our brains work. Once we are emotionally invested we introduce staggering bias to our perception filters. Right now you literally cannot perceive the correct weight of the evidence against Mormonism. It is a similar problem to those trying to argue against evolution to preserve a creationist mythology.
Let me give you a neat little example in reference to something you frequently allude to - this Nahom. To you the presence of somewhere that has a similar name on the Arabian peninsula becomes resounding proof. The presence of a place called Comoros , east of Mozambique, with a capital of Moroni however , won't even raise a flicker of concern. As an observer it looks very much like someone choosing exotic names, slightly modifying them and then writing them. Modern day apologists then produce a straw man argument that nowhere on the coast of The Arabian peninsula would ever be expected to have a long standing river, trees for boats and ore for tools and when they find one that also shares the same letters as one of the many made up names used in the fictional account claim it is incredible proof. This is craziness. The whole story fails a basic reality check: we are ascribing ocean going boat building skills to a tiny family of farming based migrants ( if you have any experience in boat building you will know how many people and how much specialist material is needed to make a vessel , never mind one capable of crossing multiple oceans. It is well outside the resource availability, tool and skillets described in the BoM- the believers answer is always then to invoke magic. If you respond to this you will find yourself doing it!)
