A cough may be evidence for a tuberculosis infection, but it would be foolish to take anyone who is coughing and say "hey! we should test for TB". Homeostasis is a necessary but far from sufficient test for biological life.

Isn't that the case with other living creatures too? I mean I'm pretty sure every human living today emerged because living creatures (usually their father and mother) created them.
But that doesn't disqualify homeostasis as evidence of life, as corporations don't emerge except when living creatures create them.
Anyway, as I understood it, homeostasis is by definition a quality of living beings. Many things have a tendency towards an equilibrium, and of course that doesn't have to have anything to do with life.
Am I misunderstanding the claim?
