someone praying for a disease to be cured is certainly putting a non-negligible probability mass on “There are things that listen to me pray and can cure disease”.
Note that P(the effectiveness of prayer is greater than zero | there is no god) > P(the effectiveness of prayer is greater than that of a placebo | there is no god).

I did think of that, but praying for someone else’s disease to be cured, without telling them, certainly qualifies.
