I'll try to make my initial question clearer...
Assume for the sake of discussion that a single being created everything.
Now, here we are inthe universe, living, doing our thing. We want to believe we have free will, correct? (I hope we all do.)
Any interference in the universe whatsoever from that god would mean some factor or factors of this universe are out of our hands, or out of the hands of what we know as natural to the universe, and in the guidence of some being. That would be a limit on our freedom.
Likewise, if we knew without doubt that this god existed, if we had evidence, would that not give us the idea that there is some other who is responsible for things, perhaps for our thoughts, words, and actions? Would that not also be an infringement upon our free will?
My thought when I began this thread was "Only in a universe without a creator/controller can free will exist". Thus, if we accept that a creator/god exists, we can either: assume we do not have free will; or assume that we have free will, in which case this creator/god is 100% apart from and outside our universe and will never have anything at all to do with any of us.
