I don't get what point you're trying to get across with this comment. The question at hand is essentially one of causality, but you seem to be avoiding it? Addressing your points one by one:
>Survivor bias. If nothing existed [1], we wouldn't be here to ask the question.
Survivor bias leading to the question is not the reason anything exists, in the same way you being alive to ask this question is not the reason you're alive. In both cases existence is simply a pre-requisite to asking the question, but it does not answer it.
>It's like asking what is P(A|A).
No, that is misinterpretation of the question. The question is not "What is the probability that anything exists, given that anything exists?", it's asking "Why does anything exist?", as per the title.
>The question "Why do I not exist" has never and will never be (seriously) asked.
Haven't given much thought to this, and at face value, yes, you're right. But "seriously" is ambiguous and there are some interesting questions here regarding the possibility of an evil demon like entity, or, more interestingly, GPT-3 posing this question.
