Is the statement "Claims demand evidence" always true?

[Thumpalumpacus]

No, I wasn't clear enough. When dealing with the concrete, evidence is necessary but not sufficient for understanding the phenomenon in question. Evidence will demonstrate its existence, but understanding only comes when evidence is analyzed using reasoning.

So yes, there is some overlap.

So how would you respond to a WLC argument, that the God idea is a rational one? Not with appeals for evidence that God is real?

I'd point out that reason cannot bring something to be in reality, that it can only explain that thing's relationship with reality and its environment.
