I had the opposite problem, Mrrzy.
My daughter (6 years then) told me once she knew how to prove that there was no god: Pray for someone you don't like to die and if he doesn't die then there is no god.

Then I, the atheist, on the one hand had to praise her for an in principle clever idea (for that's how ideas are tested in science) and on the other hand had to tell her that if there was a god he'd most surely not answer such prayers.
