Fine tuning argument assessed

[Esquilax]

But according to what we do know about the physical properties necessary for life, whether or not a universe allows life to exist is determined by the specific values of the physical constants in that universe, and physicists have discovered that altering any of the constants in our universe even just by 1% would physically prohibit the emergence of life. So maybe that's why the author of that article said that a life-prohibiting universe is vastly more probable than a life-permitting one.

Even accepting that completely, the statements "something improbable happened," and "something impossible happened," aren't the same thing. That's the fundamental weakness of the argument from fine tuning; unless you're assuming that this specific life giving universe was the goal from the start, it isn't even an argument for fine tuning at all. It's just a reminder of how uncommon things are.

Hell, the chances of your specific genetic self arising from your entire familial chain is similarly improbable, but I doubt you'd be attempting to argue that god fine tuned your relatives into having sex.
