I think you're adding an assumption that isn't justified, that this god would have had to start at what we call t=0, i.e. big bang. Part of timless physics is that there is no privileged moment in time. The laws of physics allow god to start at any point in the configuration space of the universe and evolve toward any direction. This isn't prevented by chaos theory. Chaos theory happens regardless of where you start your t=0. The laws of physics are 100% symmetric (CPT symmetry). This does not mean we will necessarily recurr either. The laws of physics are symmetric, but due to the Past Hypothesis (prior condition of the universe was very low entropy), we experience an emmergent direction in time, and if the universe is infinite and unbounded it seems like it wont recurr.
