I'm not an expert on the lore, but I've read up on some of it and checked out the lore forums. For a more detailed answer you should definitely post there, but I think they'll link you to a bunch of texts from the imperial library rather than give you a straight answer.
From what I know, the theory is that there The Elder Scrolls universe actually only has one god. And it is everything. In the beginning it was split into Anu and Padomay, which then devided into the Aedra and et'Ada, as well as the Daedra.
That link chronicles how Shor (the nordic Lorkhan) tricked Alduin (the nordic Akatosh/Auri'El) as well as the other Aedra into creating Nirn, which they were then bound to. It gets confusing, but you have to understand the nature of the god's. They're in large part shaped by the belief and worship in them. Akatosh, Auri'El, and Alduin all exist as the same being, but are separate from one another. I understand it as something similar to the the way the Trinity of Christianity is the same god but separate entities. It wasn't Alduin you saw at the end of Oblivion, it was Akatosh, who was in a sense born when the Alessian reformation caused the first dragon break -for the purposes of creating a time god more sympathetic to humans than the nordic Alduin or the Merish Auri'El-, and in another sense has always existed.
I guess a simple, but not entirely correct, way of putting it is that everything is an aspect of one Schizophrenic being, and that Akatosh and Alduin are different representatives of the same aspect.
Ugh, sorry if this post seems confusing, it's been a while since I read thoroughly through the lore and I'm kind of tired right now. You should probably post to the lore forums for better help , but I hope for now this at least makes it a little easier to understand.
