Existence is infinite, not the universe.
Notice that "before" the emergence of time's arrow and entropy, and the rapid expansion of the universe, existence simply existed, atemporally, undifferentiated and whole. Right now, existence is atemporal, undifferentiated and whole, because pure existence isn't the same as nature or the universe. Even if you think about the simplest ambient space of all natural possibilities, "existence" is even simpler than that. Nature itself is incidental to pure existence, because nature encompasses plurality and change, while existence itself is perfectly simple and unchanging: indeed, existence is separable from time and space precisely because cosmology already posits how the earliest state of the universe was before being stamped with a temporal arrow, and that state of the universe had existence yet wasn't existence per-se. Only existence per-se is infinite, because even this universe will fade into nothingness in however way it ends, big freeze, heat death, big crunch, whatever. And anything that temporally begins and ends cannot be infinite.
