I think that might depend on what one accepts as a definition of "god". From what I can tell, if there is a god, I tend to like the idea that it IS eternity and all it's possibilities, not something that lords over it. This would mean that all of us, everything we see and experience, as well as all that which is unknown to us as of yet are all part of it.
And if that's the case, Buddha was right.
"God" would simply be a process by which all possibilities are expressed in all versions of eternity, and would encompass all dimensions.
As Robert Anton Wilson used to say, "You are the master who makes the grass green."
