''You keep leaving the "as we know it" part out in most of your statements. Ever heard of the puddle analogy? It exemplifies why "fine-tuning" is BS. The universe is not fine-tuned for life. Life (as we know it) is "fine-tuned" to exist in these conditions.''

Me:

Our universe allows this life forms to exist, or better: Life could develop under those extreme circumstances.

Life adaptes, but this is only possible to a certain degree. It still stands that in absolute values most other configurations of natural constants (or even laws) can not lead to life in any form. Life requieres complexity in some form, a universe must allow this complexity. However, it is true that even simple rules can lead to complex structures:

''The universe is not fine-tuned for life. If anything, it's fine-tuned for death. Literally anywhere that's not on a planet will kill any life form, eventually. Some planets will kill all life forms as well (Venus, for instance).''

It's still possible, maybe more frequently than we know, changes in the natural constants are even more "fatal".
