When two competing belief systems come up against each other, you'd think that a single 3 O's god would be more impressive, wouldn't you?
But, many do even if, as has been argued, that means certain things that are unpalatable must be acknowledged....such as sin/evil.
You don't get much more persuasive than an infinite stick. Or an infinite carrot.
Maybe that's why christianity is popular because you only have to work really hard through one life to save yourself. The difference between watching a long boring movie versus a short cartoon (dramatization).
