"I'll pray for you."

[Esquilax]

Testing just proves that those things aren't supernatural. They never were. Religion teaches against such falsities. Superstition is evil. Supernatural, by definition is untestable. Think about it.

You seem to think that this is some magical conversation stopper. You seem to think this somehow justifies your belief in the efficacy of prayer. But if we can't say that it doesn't work, then you have exactly the same lack of reason for saying it does. And there's certainly no reason for us to take you are your word, or take anyone else at theirs, because all you've said is that your version of prayer is completely unproveable, and therefore cannot be proved to work.

Hell, given these provisos, you can't even state anything about prayer to be true, so everything you've said is just speculation anyway. You're hardly proving your position, you're just placing it all out of anyone's reach, as though that validates your assumptions.
