The Christian god is a software without user facing UI (a demon process) that is installed on host minds as functionally identical instances by the church. Exorcised demons are corrupted instances which are recognized by abberant checksums and are aborted to recover the host.
Argh, it took me a moment to repair that. OK, the null pointer (demon required but not online due to additional proofs that prevent the instantiation of the demon) results in nihilism. The test for God's existence tends to be surprisingly unproblematic when God is online.
