Studies on intercessory prayer, involving thousands of patients in randomized trials, found zero measurable difference in recovery rates between those prayed for and those not. Let me define terms first. God, in the practical sense, is a being who hears and answers prayer, at least sometimes. If that being exists, prayer should produce observable outcomes. It doesn't, not once under controlled conditions. So either God doesn't exist, or God refuses to be detected. Both options undercut the claim. People genuinely feel something during prayer, sure, but feelings aren't evidence. My framework is simple: if a claim predicts testable results, and the test comes back empty, the claim gets weaker.
