Whether or not the 'god' in the analogy created the structure that he observes, the point is that your hypothesis relies on the supernatural viewpoint in order to dispense with time. The cosmos cannot, by definition, exist within 'extra-cosmic space'. There can be no 'things around it' from whose perspective our cosmos is atemporal.

Thanks for informing me that you're Catholic. It confirms my impression that your concepts are upheld by religious beliefs. In the given case that God exists, I would not dispute your argument. I respect your perspectives, and can understand that it may sometimes be difficult not allow them to infringe upon the scientific method.
