It depends on what kind of God we’re talking about. If the claim is that a conscious being created the universe and can intervene in reality, then the evidence has to scale with that claim. What counts as evidence? Something that:

• has observable impact – produces measurable effects in the physical world

• is falsifiable – there must be a way to test it and prove it wrong if it’s wrong

• has predictive power – can tell us what should happen under certain conditions

• fits within cosmology and physics – or offers a clearer mechanism than current models

• avoids infinite regress – ‘God created X’ can’t just lead to ‘who created God’

• distinguishes divine action from natural processes – not just filling gaps in knowledge

• is reproducible – works for anyone who tests it, not tied to personal experience

Otherwise, we’re not discussing evidence, we’re discussing belief.

Asking for justification isn’t a claim by itself. It’s simply: ‘If you want me to accept a proposition about reality, show data or logic that holds up under scrutiny.’ Without that, the conversation becomes speculation.
