If there is a creator, so what?

[Ben Davis]

So if I let your arguments stand, and there is a creator, can you tell me what difference it should make to me?

That depends on whether you're talking to a theist or a deist. Your position is patently true if there's a distant, uninterested or incapable creator (the deist concept) however if there is/are interventionist, theistic god/s, the difference it/they would make would likely impact every area of your life. We're simply fortunate that there's no evidence to back up any theistic propositions, no testable claim which has ever been upheld nor any way to differentiate between theistic & deistic concepts in the realm of 'logic argumentation' (e.g. Kallam, fine-tuning etc.).

Irrespective of the actual existence of any deity, the behaviour of the believers can & does impact directly on your life. That alone requires that we understand what's going on so that we can build suitable/adequate coping mechanisms, both personal (e.g. use of reason) & social (e.g. secularism).
