I think it's possible. With the way technology advances so rapidly how could we rule it out? The "2045 Strategic Social Initiative" has as it's goal to create a holographic avatar that can upload our consciousness by the year 2045. But what if that has already happened?
If God used advanced computer simulations to show the consequences of Adams disobedience we wouldn't have to have billions of people actually suffer and die to prove his point. He could put Adam into the simulator to show him what would happen. Perhaps make him live 70 or so years, a human lifetime, in the simulator, before he ever put him in the garden. How do we know that's not what's happening?
