Scientific evidence has demonstrated that the universe IS constntly expanding. There is also evidence to suggest that at one point the universe was nothing but a single atom-speck,, and that something (The Big Bang) made it expand outward, creating the outer rim of the universe.\n\nSo we can reasonably assume that at one point the universe was essentially non-existent, and that something made it into what it is now.\n\nAs for the creation of God, the Bible doesn't cover it. Since that's the only source of Christian information we can accept as true, we *don't know* how God was created. But to answer your question: I believe it's easier for one being to have existed forever instead of our universe having existed forever. Scientific evidence supports the former and rejects the latter.
