You speak about physics and how unrealistic a bridge collapse in a movie is yet want to hand wave about the physics of golden plates showing up from a civilization 5000 miles and 1500+ years away with zero evidence that the plates ever existed other than "trust me, bro".

As you go back through history, its understandable that earlier civilizations attribute things happening around them, or things they observe, to some higher power or having completely false notions of the world, like the earth is flat for example. And then humans come to a more accurate understanding via science. How many hundreds or thousands of deities/gods have humans attributed things to during our thousands of years of existence?

God or a higher being isn't the discussion point, the discussion point is how silly it is to think that something like being led to/discovering golden plates happened at that period of time.
