"The burden of proof is on those who are believers"

Oops, off goes the proof buzzer again:)

That Latin one was better: "The proof lies upon he who affirms..." The moral is that it's better not to affirm, that is, deal in certainties. It's a sin serially committed by religion but never by any atheist worth his or her salt. If you claim certainty, that is, if you affirm, you leave yourself open, justifiably, to being asked for proof. If you merely declare faith (in public), you'll simply be asked for evidence, not proof.
