And without Anu, everything would be in a constant state of flux- anything that was created would almost immedately be destroyed or changed so much that it no longer resembeled what it once was.
First off, you didn't refute my point or restate your own point, you just stated something random. You began by saying that nothing came from Sithis, but everything came from Anu. I responded by saying that without Sithis nothing could have come from Anu (which means that at least indirectly things
do come from Sithis). You respond by saying that without Anu everything is in a state of flux, which is both untrue and beside the point.
What happens without Anu is irrelevant both because the discussion was concerning what happens without Sithis and because nothing can happen without Anu. If Anu is Everything (as you say in your first post), then how can everything be in flux without Anu (as you say in your second post) - afterall, if Anu is everything and you take away Anu then there is nothing left to be in flux. Sithis is the cause of the flux, Anu is what its causing to flux.
We're pretty much at a point where we can't make good arguments for or against; the lore isn't clear about the actual relationship between Sithis and Anu- it's possible tha Anu created both Sithis and Anuiel (although the lore denies this according to the Wiki entry.) Fact is, we can't really say anything difinitive about the primeval force of Sithis and Anuiel beyond that they simply exist and represent the polar opposites- static vs. change, good vs. evil, light vs. dark, creation vs. destruction, Yin vs. Yang...
Wiki is lame, you shouldn't use it. Go to the source texts and draw your own conclusions. I can say plenty of definite things about the primeval forces, most likely because I'm not relying on the wiki entry.

--"Sithis is the start of the house. Before him was nothing, but the foolish Altmer have names for and revere this nothing. That is because they are lazy slaves. Indeed, from the Sermons, 'stasis asks merely for itself, which is nothing.' Sithis sundered the nothing and mutated the parts, fashioning from them a myriad of possibilities. These ideas ebbed and flowed and faded away and this is how it should have been."
--"Anuiel, as all souls, was given to self-reflection, and for this he needed to differentiate between his forms, attributes, and intellects. Thus was born Sithis, who was the sum of all the limitations Anuiel would utilize to ponder himself."
Sithis is the force that limits and divides (which are the same thing). It sunders the nothing - which is in reality
one thing, but when there is only one thing there might as well be nothing. Anuiel limits/divides himself and Sithis being born is the natural consequence of this, because that's what Sithis is, the force that limits and divides. Whether you want to say that Sithis was born and divided everything or whether everything was divided and thus Sithis was born doesn't matter because this is all before linear time where everything happens at once.
