A wonderful way to prove one’s own ignorance:
A:
Could you tell me why fire is not alive?
B:
Uh…fire is a catalyst, guy. Didn’t your mommy teach you anything?
A:
Um, at the risk of descending to your level, it seems that your mommy was your only source of your home-schooling. Fire is not a catalyst: By definition, a catalyst is a substance added to a chemical reaction that increases the reaction rate by providing a reaction path with a lower activation energy. The catalyst is not consumed (i.e., does not lose mass) in the process. Heat nor fire are catalysts, because they are not substances.
B:
Catalyst A substance, usually used in small amounts relative to the reactants, that modifies and increases the rate of a reaction without being consumed in the process.
Fire A rapid, persistent chemical change that releases heat and light and is accompanied by flame, especially the exothermic oxidation of a combustible substance.
Does fire increase the rate of reaction? Definately. Is fire consumed in the process? Nope. Does fire induce a change from one state to another? Yes. Are all fires catalysts? By definition, yes, because they consume fuel and oxygen, produce heat and cause a conversion. Are all catalytsts fire? No. Is there any particular reason we are discussing this outside of the fact that certain evo’s were proved incorrect in their definition of nonliving? Not at all.

Not to mention of course that it’s definition as a catalyst isn’t really directly related to whether or not it is alive…
