I think the Problem of Evil actually makes sense when you consider eternity and infinity. The infinity that God is and Eternity that Heaven is, earthly sufferings really will be seen to be nothing. You probably don't worry about that exam anymore that you were studying for as a kid. As for the boulder thing, you may as well say maths is illogical as "can you make something greater than infinity" while infinity + 1 is equal to infinity.

As for Occam's razor- how does it explain the life, death and resurrection of Jesus Christ? There's not really a simple explanation to why 2000 years ago, a lot of guys simultaneously told of the same dude who rose from the dead, then lived a life of suffering and no gain and end up dying because they wouldn't claim to be wrong. Along with hundreds of these early Christians turning into thousands. Something big did happen - we count our years by it. It's as if God actually did enter earth as a human.
