Dualism

[Purple Rabbit]

God tells Moses in Exodus 33 that no one can see him, but only see where he has been. To me this is a definite statement regarding proof of God not being possible.

There are two problems with that answer:

1) Proof of existence does not imply visibility. It is enough that god's existence is traceable. Even for science this suffices. No scientist has ever seen an electron, still according to science there is enough proof for it's existence. So I would say this leaves no room for your unprovability claim.

2) If you do interpret this as a clear statement that god is unprovable then the bible defines that god (among other things) is unprovable. Referring to the bible definition of god as you did, means your reasoning has been circular for your claim becomes:

(A) god's definition in the bible states that god is unprovable
(B) therefore god's existence is unprovable

This is clearly fallacious reasoning.
