The anthropic principle states that I'm a typical sapient-level observer. What this implies is that if there are two groups of sapient-level observers, then I am most likely to find myself in the larger group. For ex: in a two-party country where voting is mandatory, my favorite candidate is most likely to win. Similarly, if there are two groups of sapient-level observers (us and aliens), then I am most likely to be part of the larger group. Since I am part of mankind and not part of the trillion member alien race that has colonized the galaxy, there's a high chance that such an alien race does not exist. The only other probable scenario is that there are many planet-bound sapient-level species to counteract the existence of a single godly alien race. In such a case, it wouldn't be too rare to find myself as part of a planet-bound sapient-level species.
Is there a way to know which one of the two scenarios is more likely? For ex, wiping my memories and then doing a self-check, noting down which group I'm a part of, and then repeating the process over and over again?
