Imagine a jury told a theory is elegant and coherent but shown no physical evidence—most would still ask for data. The other side's strongest move is explanatory: theism supposedly grounds reason, morality, and intelligibility. But that's a philosophical preference, not a measurement, and coherence doesn't make a claim true. The testable claims keep failing: the STEP intercessory-prayer trial found no benefit, and Pew's country-level variation tracks culture more than any universal signal. Where is the controlled evidence for theism's core claims? Without it, calling theism the better foundation is just relabeling an untested hypothesis as an explanation.
