The way I understand it, it says that the probability of God not existing is like 1 / infinity. I wonder if there are any flaws in the logic below that I don't see.
A possible interpretation can go like this:
Let's assume that there's indeed nothing divine about our universe. Most importantly there are no souls and there's nothing "magical", other-dimensionly about the consciousness and therefore life. Everything is all just evolutionary rules that we don't understand yet, because we haven't uncovered 100% of the physics laws. But at some point we will uncover them. Once that happens, we will be able to put these evolutionary rules inside a computer program, run it very fast and after, say about a week, we should get a fairly similar copy of our universe. That new universe, even though a simulation, would have been created by the same evolutionary rules as ours, so it will be as real as it gets - not just some illusion. So real that it may actually be a crime to pull the plug, because you'll be destroying lives. The only difference for that universe will be that it exists in a different dimension.
The life inside it will reach the point where they can do the same and spin their own universes. And this can go on forever (limited by the processing power of our computer, but it can be very powerful). We can spin multiple such universes, the aliens in ours can do the same and as a result our universe would have created millions of child, grandchild, etc. universes.
Seeing all this, we start asking - what is the chance that we actually live in a universe that is not like this? And the answer is 1 / infinity (actually not infinity, but limited by the original computer's resources, but still it can potentially be a very large number).
The original universe that started all this may not have a creator, may be very different from ours and it may actually have a relatively simple explanation of how it all began. But if we don't live there - it's hard to speculate.
So is it really safe to say that according to this theory, the chances of God not existing (in our universe) is like 1 / infinity? Are there any flaws in the above? Is the theory scientifically sound at all?
EDIT: I'd like to point out that the purpose of the question is not to ask if we live in a simulation or not. This can only be the case if consciousness can be achieved using simple if-then-else computer logic. I don't think that's possible, but the purpose of the question is to ask - if we assume this is actually the case (because many atheists believe this) then the simulation theory becomes a very real thing, so is it scientifically ok to make that 1/infinity statement. And if not - why not?
