Belaqua, there's a problem that is even more essential than argument-- the reason FOR argument. If you have an interest in people understanding and accepting your view of an existent God, then it's not really up to you what kind of evidence they will / won't accept: you'll have either to persuade them, or to have them continue to disregard your view. That's because in order to be convinced by your evidence, someone will have to come into your world and try prayer, ascetic discipline, and so on-- but if someone doesn't believe, they are unlikely to spend hundreds of hours trying to immerse themselves in the world which will provide your type of evidence.
And that's why the objective evidence required for good science is so valuable-- it doesn't have to meet you in the way. Computers will get made and run whether you believe in electrochemistry or not. Planes will fly whether you accept the evidence for things like air pressure and gravity or not.
