Is this a typical religious "either-or" question allowing for only two alternative answers, both FALSE? I think so. Interesting that the question uses a lower case "a god" and an initial caps "God'.
The short answer to "Where does it leave God as our creator" is: NOWHERE. No "God".
There are two theories that make more sense than a "God". One is conventional, and the other is rather more far-fetched than the "God" idea, but still makes more sense.
The more conventional one is that we are a separate species, branched off from apes and monkeys hundreds of thousands to millions of years ago.
The far-fetched one is that we are genetically engineered by aliens, about 400,000 years ago. We are a hybrid of hominid and alien genes, which could explain some anomalies in our chromosomal makeup compared to apes. Those aliens that created our race are the gods (lower case) mentioned in texts much older than the Jewish Old Testament, which made their way, rather garbled, into the Old Testament.
See the brief mention about the annunaki by Sitchin on my profile page:
That is just a start; there is much more information out there about the "gods" (not "God"), and our history absent religious dogma.
