Could be that God is not the kind of thing that possesses the kinds of properties traditionally attributed to it: or that the concept of a "necessary being" seems like an oxymoron if we understand that all beings which exist could be conceived as not existing and that there is no logically necessary reason that something "ought" to exist: God is used as an explanatory account, but if nothing existed then God would not be argued as having necessary existence. This is because the idea that something must have "necessary existence", especially some particular thing, is metaphysically presumptuous and completely unfalsifiable. I don't think anything in particular can be shown to have a necessary existence. And even if there was a concept of God such that the absence of such a being could be seen as counterintuitive, that does not by itself preclude the possibility of it being non-existent, since it could just reflect a limitation on reason itself as a means of deriving certain kinds of knowledge about the nature of ultimate reality.
