I disagree with the method.
And if Doug suggests the main focus of philosophy of religion is about whether God exists. He’s going for a lifetime job.
Most Christians will tell you that you they can not prove god exists and I have never met one that can or says he can. And Christians say they can not prove to me god exists, other than by their belief system or miracles they see, hear, or experience. They then attribute these chosen miracles to god.
As belief can be anything, nobody has ever won an argument against a belief system. And you will lose because god does exist in the Christian’s mind.
Now, the point being, that when a Christian tells me about their god that’s in their mind, I do not argue with them because I do not have anything better to offer that’s better than eternal life. For some people the only thing that is keeping them from blowing their brains out is the belief that they are going to heaven.
If you got the answer then you can stop all the suicide bombers.
