If the infinite multiverse is true, then everything is true, including that there is a Yahweh who rules some universe, which could be ours. There would actually be an infinite amount of Yahweh-like beings. Actually, there would be an infinite amount of Yahwehs at war with an infinte amount of anti-Yahwehs. Or why wouldn't there be one universe in which a certain being became so powerful it figured out how to control the rest of the multiverse, including our universe? Infinite multiverse is simply bunk.
