I don’t see how multiverses eliminate God. The multiverse is “something”. How did the multiverse create itself? Where did the multiverse gets its intelligence and existence to get it going in the first place? Putting an infinity to endless modeling doesn’t really eliminate God. God could be in every one of this universes.
I have seen a tendency to refute the possibility of a multiverse from Christians. As you say, it can’t be used as an argument against God, so why the reticence?
I think it’s because our knowledge of what entails ‘everything’ has obviously increased over the last couple of millennium, so what ‘everything’ actually is is consequently growing at an ever increasing rate.
Anselm’s description of God as being ‘that which nothing greater can be conceived’ sounds like it a safe bet. It encompasses everything. The greatest thing that you can imagine, God is it. The problem is lack of imagination.
People a couple of thousand years ago thought that everything was all that they could experience. So much so that filling a boat with a couple of all the animals that existed wouldn’t be too much of a problem when all the animals they knew ran into a few dozen. And God created the world. How much bigger does He need to be? Land and seas, pretty lights in the sky and we are the centre of creation.
Well, we all know where that parochial view went. And at every step in our knowledge (we go around the sun?), we become smaller in relationship to what everything entails, a fact with which people had and still do have a problem (a quick hello to all the Young Earthers and ID fans here). The bigger the stage gets, the smaller the role we have in the production. And God has to become more powerful than we used to, or could, imagine at every step. And I think that this becomes a little difficult for some people.
But God created everything: the world and the sun and moon! Well, actually, we’re just one of quite a few planets. Oh, OK, then he created everything: the whole solar system. Well, actually, there are a few billion of these in the galaxy. There are? Well, OK. Then that’s everything and He created this galaxy of systems
Except we have to keep cranking it up. Billions of galaxies. And billions more outside of the observable universe. And maybe an infinity of universes.
So if you asked anyone even a hundred years ago to imagine something ‘greater than which nothing can be conceived’, that persons conception would have been woefully lacking. People for centuries have been saying: ‘THIS is how big God is. He created EVERYTHING’. Except that science keeps saying: ‘Excuse me, but if there is a God, He needs to be a lot bigger than you currently imagine’.
And I think we left behind what we can imagine God to be a long time ago. If it was just this world, then people can conceive God having made it. Maybe all the planets. But we are then already waaaay past what we can conceive. The distances, even in our own backyard, are literally unimageninable.
God keeps needing to be bigger. Which shouldn’t be a problem. Big deal, whatever you find, God did it. But I think people are psychologically unable to keep cranking their concept of God ever upwards. What they can conceive keeps getting bigger, so their concept of God has to keep getting bigger and if you already thought He was as big as He could be, that might be a problem.
