Can we "know" God doesn't exist.

11. Logically self-contradictory ones only

The standard omnipootent omniscient omnibenevolent version is DOA, but to deserve the name, any god would have to be beyond human understanding. If for some reason a god wished to test human capacity to manage cognitive dissonance by implanting the concept of a benign deity in the face of seemingly random horrific diseases and natural disasters, that experiment would look an awful lot like reality. Such a god would not really be omnibenevolent of course, but all that means is most believers would be mistaken, not that a god like that is nonexistent.

Likely? Almost impossibly unllikely, but how would we prove otherwise? Does the mold in the petri dish know if the guy in the lab coat is a real PhD? Why, purely theoretically, would we be capable of disproving a god who wished to remain ineffable?

So all we can do is disprove specific god theories that are similarly impossible by either internal contradiction or incompatibility with reality. The married bachelor god is impossible. The triple-omni god is refuted by, for example, infant cancers. Bot Oogabooga the invisible Snake God spirit who implants evil thoughts into young men? Impossible to disprove. Even if we could neurologically determine the mechanics of every evil thought, how could we prove it's not Oogabooga causing those neurons and synapses and axons to do their stuff?
