No, not at all. This is all just more "how", which l already understood pretty well, thank you. My point was that none of this explains "why" these particular mechanisms exist, instead of others the do something else. Part of the answer is the state of affairs that allows us to exist to ask the question in the first place.

My point, exactly. A universe where these things turned out differently
would lack people to ask the question. So, the question is "Why did things turn out this way?", not "How did things turn out?". I haven't the first clue, and you don't seem to either.
