Err... nothing to do with what I was saying, but... okay, if you like.
There's a hypothesis out there -- assuming that computer technology will eventually reach the point where computers can simulate vast numbers of entire universes, the probability that our universe is one such simulation greatly exceeds the probability that it's real, so we would most likely be just computer programs running in a vast software model. Or so the hypothesis claims. Of course, without evidence, it's just as much an article of faith as any religious belief.
