Can we prove Christianity wrong?

[Purple Rabbit]

Depends on the type of proof you want. Scientific investigation needs falsifiable statements, most christian statements however are not formulated falsifiable. There is no test we can do that unambigiously falsifies statements about the christian god, for instance that he is all good. Because of the missing falsifiability characteristic of theistic statements, it is always possible for the theist to devise a posterori arguments, i.e. arguments that after the experiment has been done explains away the result. With truly falsifiable statements this is not possible. Such a statement can either be falsified or verified by the right experiment.

For example take the theistic statements that prayer helps. Through a double blind experiment on patients recovering from operation it was found that patients that were prayed for had a slightly worse recovering history. This is probably due to added stress in the case of patients that knew they were prayed for. Does the average theist register this as proof that prayer is bull, well of course not, because god can't be tested or some other excuse that was thought up afterwards. With unfalsifiable statements this will always be possible. It is always possible to concoct some explanation afterwards. Try it yourself. With a posteriori arguments it is easy to claim that kobolds exist in your backyard, even if you have no backyard at all.
