In all the zillions of galaxies that exist, the ones where intelligent life developed are more likely to be observed by intelligent life. Therefore, intelligent life can't make any arguments based on probability that intelligent life developed, because our observation of the phenomenon is not independent.
And maybe some people have used it to avoid explanation, but it also doesn't really conflict with any effort to explain either.
Saying that we wouldn't be here to ask the question is not an answer to anything because we are here and we need to understand how and why.
1. "What the mechanisms or rules that explain or seem to govern this observable phenomenon?"
2. "The rules behind our own existence seem unique or low-probability, can I use our N=1 sample to safely assume we are inherently special and/or the existence of a god?"
