All religions claim to have the truth -- the revelation from god (or gods) as to how us humans should live our lives (and worship the supernatural). But the fact is that no religion covers even a majority of the world's people -- and each is further broken down into several (or even hundreds) of different sects (all of whom, of course, have the only truth). If there is a god/gods, then he/she/they either have a very loose definition of the truth or a very good sense of humor.
The percentages above are from the Pew Research Center's report titled "The Global Religious Landscape".
