If you're going by that logic, though, then even the odds that you are a simulation are utterly dwarfed by the odds that, say, you are just a random event in the quantum foam at the end of the universe that for a fraction of a second comes together with your exact brain and all your memories and experiences, and then is gone. Simulations in any given finite universe would still be finite, but end of the universe quantum fluctuation would happen an infinite number of times, no matter how low the odds are, given an infinite post-heat death time frame.

As I've been saying, following that same form of logic inevitably leads to a lot of bizarre conclusions, many much weirder then the simulation hypothesis.
