There is no god. If there were, you could have straightforward conversations with him whenever you wanted (and thus you could ask him this question, instead of asking it here). And prayer has no confirmed effects other than natural psychological and biochemical effects (such as placebo and anxiety relief), which is equally accomplished by entirely godless meditation.
Is prayer just a way of centering oneself neurochemically (all maintained within the brain alone) or does prayer really connect one with "God"? How does one know if one is really communicating with "God"?
