If god existed and were an omniscient creator then I contend we have no free will. God would know the future course of any creation by its omniscience. Thus, in the act of creation god determined the future course of that creation. Because god created, and knew the future course of that creation from before (doesnt make much sense but you get the idea) it created, we cannot have free will.

This is tantamount to saying that if there is a truth of the matter about the future, we have no free will, which is demonstrably false. Take this sentence:
D: Dunemeister will eat granola and yoghurt tomorrow morning at 8 A.M.
On what conditions could D be true? Well, it's true if I eat the specified food at the specified time. What would MAKE D true? Well, my decision at 8 A.M. tomorrow would. Will I do so or not? Right now, I don't know. But on the morrow I will find out.
So what if it's true? That is, what if it's true that at 8 A.M., I will eat granola and yoghurt tomorrow at 8? Does that mean I
can't do otherwise? No. It just means that I
won't do otherwise. So my freedom is intact.
God's knowledge of D, you'll notice, is irrelevant. God's knowing D doesn't make D true. It's the other way around. D's being true is what gives God the particular knowledge he has about D. And D is true because, at the time specified in D, I freely take the actions specified in D. I
could do otherwise, but as it happens, I
won't.
