Answer 1

It’s the wrong question to ask.

Fires just burn. the law of physics simply told them to burn at a specific spectrum and there is nothing you can do about it. Well maybe not until we reach Kardashev Scale level 5 and be able to rewrite physics. Why is the gravitational constant G? We don’t know, it is what it is

#The better question is : why do our eyes evolve to be able to see Fire?

I’m not going into deep details, but the Occam’s Razor is our land-based ancestors probably won’t survive in the wild if they can’t even see imminent dangers. Every senses and organs we have is a product of billions of genetic mutation that favors our survival.
