It should come as no surprise to anyone that humans are capable of not believing their own eyes.
For example, Old Sol appears to rise and set in metronomic regularity. Unless, of course, it states in a 2,000+ year old book, for a time the sun appeared frozen in place.
You know enough about the natural world to reject the existence of Ghouls and Goblins. Yet be fine with the belief in Angels and Saints.
Do you see the problem here?
There are many examples in the book that defy the laws of physics. The “get around” is to always believe the book and not your lying eyes.
