The practical consequence of my position is that moral duty and human dignity need a foundation sturdier than consensus. Without God, even something like torturing a child for fun becomes a preference, just one most people happen to reject. The other side might say secular ethics handles this, and fair enough, atheists can be decent people, but that doesn't explain why objective moral facts exist at all. Add the fine-tuning of physics and the contingency of the universe, and theism looks more reasonable than the alternative's "we don't know yet."

The practical cost of the other side's view is that moral accountability gets thinner: without God, "torturing a child for fun is wrong" becomes a very strong preference, not an objective fact. My opponent's history-of-science point is fair, lightning and disease did get natural answers. But that pattern explains mechanisms inside the universe, not why there's a universe at all or why cruelty is objectively wrong. Those aren't gaps waiting on a better theory; they're different questions. So theism still carries more weight where it matters most.

A pattern can be real and still be the wrong tool for the job. My opponent is right that lightning and disease got natural explanations, but those are mechanisms inside the world. The question of why there's a world at all, or why cruelty is objectively wrong rather than just widely disliked, isn't another mechanism waiting to be found. The other side says moral horror can be real without a cosmic lawgiver. Sure, the horror is real. But real feelings don't create a duty that binds someone who lacks them. Imagine a society that feels nothing at cruelty; on their view we can only say we disapprove, not that they're wrong. That's why theism still carries more weight.
