Interesting question. I choose to believe about somethings that I know are not provable - but when I do so I try my best to make sure I state that what I'm saying is a statement of faith ONLY (cannot be proved right or wrong). For example... my faith that people are born "good" and mostly only diverge from the things we consider "good" due to fear and laziness. This cannot be proven but it is important for me as a basis from which I draw my conclusions about the world.
To apply it to your example about the moose, the belief would come NOT in the debate about whether it's actually standing in a marsh or not (this much should be obvious by all non-blind observers) BUT in the theory about HOW it got there in the first place. Maybe it's my faith , let's say, that moose are by nature attracted to moisture -so the "why" for me as to what this moose is doing in the marsh is already set for me.
I realize that this is a poor example because whether or not moose are attracted moisture can be tested and proven one way or the other. I'm just trying to illustrate HOW faith and belief come into play in real life situations.
