He was loved for his writing until he wrote the "Age of Reason". They despised him for that.

All a simulation is, is a construct following a set of rules someone created. A Dream could be similar I suspect. The main difference between a simulation and a dream is that a simulation can be made to be very different from the world you live in if that is the choice. Dreams on the other hand tend to be constructed from the things in our own world. I do know dreams can have rather alien stuff as well.

One of the other things is a simulation because of the rules is definitely more ordered than a dream. That one difference is why I wouldn't consider it a dream. Things seem too orderly and consistent for a dream. Though it is possible the creator's dreams are different.

Ultimately as a Deist. I don't so much try to actually define the creator. For me knowing there is one is sufficient. I observe and use reason. What I cannot observe is speculation and I can make up many different speculations. :)
