Cris, I think that is the question at hand isn't it? If God is said to be infinite, and we propose that the universe is infinite, then, conclusively, we could say that the universe is God, since actual infinites would be identical. Furthermore, to say that the universe is infinite would imply that it itself does have consciousness.
I think to understand this properly, the distinction must be made between an actual infinite and a potential infinite. If you mean by saying, "what if the universe is infinite?" you mean potentially infinite, then the answer is already known. The universe is potentially infinite, meaning, with a beginning point, it will continue forever, meeting out an actually infinite number of possibilities. However, if, by infinite, you refer to actual infinity, that is, a complete set, without room for change, growth, meeting out of potential, etc... then it can easily be shown that the universe is not actually infinite.
When one speaks of God as being infinite, they usually mean that God is actually infinite, rather than potentially infinite. If God were potentially infinite, He would be limited, and would not be omnipresent, omnipotent, omnibenvolent, etc... However, as an actual infinite, God can be said to be such things. Therefore, if one is speaking of God as an actual infinite, then one may not say that God is the universe, since we already know that the universe cannot be actually infinite. However, if one believes God to be potentially infinite, just as we all are, then it may be possible to say that God is the universe, since, just as us, the universe is potentially infinite. In such a way, God, then, is simply the interconnectedness of all things, and may or may not be a conscious entity, since it is unknown that the universe itself has reached the point of universal consciousness.
Furthermore, in being able to say that the universe is not actually infinite, we can assert that the universe had a beginning. In fact, it is generally agreed upon that the universe had a beginning within the scientific community, within the religious community, and pretty much within the philosophical community as well. In making this assertion, there is strong likelyhood that there existed something prior to the beginning of the universe that set it into motion, since nothing can come out of nothing, and in fact ONLY nothing can come out of nothing.
So, since it is very much agreed upon that the universe had a beginning, and under the notion of infinities it seems logically false to say that there only exists potential infinites, one may conclude strongly, but not totally, that there exists an actual infinite. We call this actual infinite God, but it cannot be said to be the universe itself.
