I agree that multiple gods makes no sense. To create everything, a god would have to be omnipotent.
I disagree. According to current physics (as I understand it), it is possible for something like a quantum fluctuation, a black hole (Lee Smolin's hypothesis), or the collision of two "branes" to cause a Big Bang, i.e. "create everything." If they're correct, then omnipotence is not needed to create everything. A group of non-omnipotent gods--or, for that matter, even creatures like ourselves or our sapient robotic progeny--could create a new Universe by triggering the right sort of quantum fluctuation or creating a black hole.
I think multiple gods make more sense than a single omnipotent god, especially if we're talking about semantic-thinking, talking, symbol-using personal gods. Reductio ad absurdum: Let's start with a single god in its "natural" state, i.e. before it has created anything else. There is nothing for it to sense (however it would sense things). There is no time in which it can sense any thing or think any thoughts. There is no space wherein it can have extension. There is no one for it to talk to, or learn how to talk from, or anything it can point to and babble at to learn/create its first word. This god is supposed to be "pure consciousness," but there is nothing for it to be conscious of
. Which means: in this state, there is no difference between consciousness and unconsciousness. This god is (so the believers tell us) timeless, space-less, and immaterial. Each of these is a negation, a descriptor of nothingness. They say what it isn't, but nothing about what it is
. Now we can add another negation--unconscious--to the list. And we're back to nothing.
Now, if you had multiple gods, then each god has something of which to be aware: the other gods, and something to talk to: the other gods, and something to talk about: the other gods. Of course the "timeless, spaceless, immaterial" aspects still get in the way. If gods are timeless, there's no time in which they can experience awareness of each other. There's no space in which they can have extension, or positional relationship to each other. There's nothing for them to be made of, and thus nothing for them to perceive, and we're back to nothing. But, if you've got multiple gods, and you permit them to have something like time, something like space, and something to be made of (it could be something other than matter/energy, like maybe "spacetime geometry"), then they have the option of being something, and of being conscious, language-using beings. It's not like raising an infant in a sensory-deprivation tank and expecting him/her to be able to emerge as a thinking, talking adult.
You cannot logically have more than one omnipotent being. If you can't figure that out, ask me. I promise to use small words.
L6, my guess as to what he would answer goes something like this: if Omnipotent Being #1 wants to accomplish goal X, and Omnipotent Being #2 wants to accomplish incompatible goal Y at the same time and in the same respect (such as seeking to win a competitive game between the two of them), then one, the other, or both fail to achieve their goal. The one (or both) that fails, is not omnipotent.
Personally, I don't think actual omnipotence is logically possible and I find the notion of a creator God to be unlikely.
