>A man going to the moon does not fit my pre-rational structure of thought therefore I do not need to believe it
How can one cope?
Memes aside, how does one draw the line between hinge propositions such as "there is an external world" which you have no grounds to doubt and something like "no man has ever went to the moon"?

Is there a non-arbitrary distinction?
