The incredible Satan

Let us further assume that this universe is inhabited by many intelligent civilisations, that some of these have the capability to create simulations of universes or portions thereof and that they are indeed performing such simulations, for whatever reason (research, recreation, etc.).
It is also reasonable to assume that such a civilisation would run many of such simulations simultaneously (statistical accuracy in research or a recreational activity that is done by many, like computer games in our society).
The result would be that simulated realities would far outnumber the physical realities.
For example if there are 1000 species that run simulations and each of them runs 1000 realities concurrently (which is quite a low number), there would already be 1000000 simulated realities versus 1 physical reality.
In this case, the probability that we ourselves live in this physical reality would be 0.0001%, the probability that we live in one of the simulated realities would be 99.9999%.
And this could very well be even higher if we assume a higher number of concurrently run simulations per civilisation, and the possibility that simulated civilisations themselves could be running simulations.
