Firstly I wouldn't describe myself as religious, I'd say agnostic but open minded.

The point of why would suffering occur if god existed, well surely then if god merely prevented everything negative then free will wouldn't exist. God is merely a guiding force who some people choose to ignore. Also without pain the concept of pleasure has no meaning.

No matter what your outlook you have to admit in general religion has plenty of positive messages, honesty, respect to name a few.

The point that the world and the human body is so well designed that it must have been devine intervention I believe is flawed. If the universe is infinite (I don't believe it is but thats not the point) then the laws of probability is that somewhere there will be the perfect series of events which bring about the existence of the human race.

I personally don't see how people can be so dismissive of something which has no evidence to the disprove it.
