Faith healing couple acquitted of manslaughter charges! How can this happen?

The belief in a being in the sky in not necessary for prayer. There is a huge difference between prayer and 'talking to yourself'.

This strikes me as quite a contradictory statement. You say that belief in a being in the sky is not necessary to prayer. Let's accept this as true for the moment, because you go on to say that there is a "huge" difference between prayer and talking to yourself.

Now if person X does not believe in gods but still prays, it is should be quite obvious that he does not believe he is praying to anyone; ergo he is talking to himself.

So either this "huge" difference does not exist, or to pray you must first believe in god.
