You know, the flat earth reality is a theory that worked for hundreds of years and still works for a lot of people. It provides an explanation that works...I'm sure that there were even testimonials from sailors that said they saw dragons on the edge and witnessed ships fall off the edge. It's only through intellectual endeavor, science and experimentation that the truth is revealed. Makes you wonder...just how many little theories of life we use every day that work, but in the future will be proven to be wrong? I mean, like how many human sacrifices do you think it took before they wised up and figured it gave the priests a full-time, prestigious job and nothing more?
