Ontology of God--Theological Noncognitivist View

Dark energy. We cannot yet directly observe it. We can observe it's affects, but not it itself.

Yes, thank you for pointing that out. This is an area of science that is still being explored. Scientists have given a name to a force which theoretically must exist due to the observations they have made regarding its effect on other objects:

The difference is that dark energy has measurable effects, even if the energy itself is not yet directly observable. God does not.
