At the risk of batting for the wrong side, as it were, why is an eternal god not logical? Time, so far as we can tell, is a facet of this universe, and as such anything outside of this universe isn't subject to the usual understanding of existence that we have. Is 'outside of time' functionally any different to eternal or infinite? It begs questions about how the two would interact, given that our understanding of anything that qualifies as interaction requires a time component, but still.
I ask because it's the same question I ask when believers tell me, in the rich vein of William Laine Craig, that reality can't be an infinite thing in which our finite universe resides.
