Here's a surprising one: a 2006 study of 1,802 heart surgery patients found that strangers praying for them had zero measurable effect on recovery. If God actually intervenes in the world, you'd expect something. But the prayers changed nothing. That's the pattern across every testable claim about God — intercessory prayer, miracles, answered requests. When we can actually measure it, He doesn't show up. And consider this: not a single scientific discovery has ever required God to explain it. Every mystery we've solved, from disease to the cosmos, was solved through natural causes. The evidence consistently points one way.

I'll grant you that the fine-tuning numbers are genuinely striking—the cosmological constant really does look absurdly precise. But that doesn't get us to God. It gets us to survivorship bias. We can only observe a universe that permits observers, so of course we find ourselves in one with fine-tuned constants. That's not evidence of design; it's a logical necessity of being here. And if God is the explanation, what determines which constants He chose? You've just moved the mystery up a level without explaining it. So the fine-tuning is real, but the leap to a designer is the part that fails.

Here's a surprising number: string theory allows something like 10^500 possible universes with different physical constants. That's not a trick—it's a real calculation. If even a tiny fraction of those configurations exist, we'd expect to find ourselves in one that supports life, no designer required. Fine-tuning stops being miraculous and starts being a selection effect, exactly like being surprised you're standing in the one spot on Earth not covered by ocean. You're alive, so of course the conditions look perfect. That doesn't point to God; it points to a vast, mostly inhospitable reality.
