Well, not trying to spoil anything here, but from what I remember the first one didn't mention them, it was in AC2 where they start to get into a pre-human civilization that was here first.
So they're not so much space gods, just advanced people that were here before us. It's cool that they added a sci-fi element to the story, but I don't want to say much else.
The story is always about Desmond, who goes into a machine to relive the memories of his ancient ancestors. The other stuff was always treated as a hinted-at mystery that they didn't get into that much until AC3.
