The argument that we probably live in a simulation is the specific argument in support of theism that the OP invokes (but does not mention specifically).
I may add that the SA forces us to adopt theism as a consequence of current physical theory, not as some modification to current theory for which we require new evidence, and this is what makes it especially powerful.
I was an atheist until I updated on the SA, and I have yet to find any rational opposition to it.
