When faced with the awkward problem that there is absolutely no evidence for the existence of God, some theists will claim that God exists in a realm outside of space and time, and therefore will remain elusive and immeasurable. This is all very well in a sense (other than the fact that there is no reason whatsoever to believe that such a being exists), but it is in direct contradiction to other attributes often ascribed to God.
Omnipresence would imply that on some level God exists everywhere in spacetime, whether or not this would be detectable to us is another matter entirely, but according to this God would be everywhere you look, woven into the very fabric of space as it were. How can a God exist outside of space and time, yet exist everywhere in space? That would be like saying I am inside a room whilst also not being inside it at the same time. It’s not logically consistent to assert that God is omnipresent and outside of space and time.
To move water molecules, you’d need some kind of input energy – an arm moving a paddle, for example. In order to part the red sea, God would either have had to transfer some energy from somewhere in order to move the water molecules, or God would have had to have broken the laws of energy conservation and created some energy out of nothing. Again it is not logically consistent to assert that a being that exists outside of space and time could have that level of interaction with matter and energy within space and time. Also, whether or not God himself is directly detectable, had we established some kind of measuring devices during the supposed parting of the red sea we would have seen an input of energy either being transferred inexplicably or coming from nowhere – in other words evidence for God would be within the grasp of science.
The Judeo-Christian God doesn’t just input energy into moving water molecules either, he inseminates a young lady, and then is born into a human body. It is ludicrous to assert that a being that exists outside space and time could do such a thing, and again if such a thing did happen and there were people around to observe it, some more indirect evidence of God would be available.
The reason that theists assert that God is beyond space and time is because this gets them out of the awkward predicament of their being absolutely no evidence in favour of the existence of God, by stating that you never will be able to find the evidence. However the central tenants of their beliefs are in direct contradiction to this. Their God very much has a role within space and time, and should thus be at least indirectly observable. It is logically inconsistent to state the God can be omnipresent, and have an active role in events within the universe if he exists outside of it. Either God is outside of space and time, and cannot interact with matter or be omnipresent, or God is within space and time and thus at least indirectly observable. Theists use the ‘outside space and time’ notion as a cop out to avoid the awkward lack of evidence, however it doesn’t really make sense. Theists need to face up to the fact that their God should have evidence, but doesn’t….
