I know there is no god with the same conviction I know there are no invisible pink unicorns in my backyard. I have no clue what Jung's god beliefs are.
The evidence is overwhelming that god beliefs originate from human superstitions.
There is no evidence of gods.
The only god one cannot test for (IE the one you cannot disprove) is the one defined specifically to fit outside the realm of scientific inquiry. No humans believed in such a god until evidence began to mount against the existence of gods.
Virtually all theists are atheistic about at least some god beliefs and usually they are atheistic about everyone's god beliefs that are substantially different from their own.
Most or maybe even all agnostics have no trouble being atheistic about at least some god beliefs. I doubt many agnostics include Zeus and Pele in their "you cannot disprove god" declaration. If you can disprove one, why not two? If you can disprove 2 why not 10? There are a finite number of people on the planet, there must be a finite number of god beliefs. We should be able to disprove a finite number of god beliefs.
Are god beliefs the thing to disprove, or are we to disprove some purposefully defined version of a god no culture actually described until very late in the history of our specie's existence? Original gods supposedly made their presence known to ancient peoples. Now we have people claiming the evidence of gods' existence is a visitation via their thoughts and/or exist only outside of a Universe the gods supposedly initiated.
Seems about the same as belief in invisible pink unicorns if you ask me.
