The point is that the questions of “why” physical constants happen to be compatible with intelligence or “how” they got that way are meaningless, since they obviously cannot be asked unless the constants do in fact permit intelligence to arise. As I noted earlier, this is a form of the Texas Sharpshooter joke.
And I'll ask you the same question:
Where in your experience have you seen something come from nothing (or in the case of the universe - everything coming from nothing)?
