Burden of Proof

[Welsh cake]

Strictly speaking there isn't anything in atheism that rules out the existence of a god- atheism just "rules out" belief in the existence of a god - not that Zone seemed to have this sort of usage in mind,but I figured it deserved mention.

Agnosticism sure. But on the narrower subject of belief/disbelief, Atheism is broadly the position of being "without god or gods". There's no room for speculating deities within just Atheism itself, just as there is no room for any speculation of the absence/non-existence of deities within Theism solely.
