What is the evolutionary advantage of seeing in the "visible spectrum"?

Is there any reason we see in the spectrum of light we do? For example, why not slightly extend to see IR and UV, since they affect us every day? Are we slowly evolving those capabilities, or would that be useless.

I'd think having something close to thermal vision like seeing IR could provide some sort of hunting edge back in the day. Am I wrong?

If you look at the wavelengths of light that penetrate our atmosphere, they fall in the visible spectrum.

We evolved to detect what "lit-up" the world

IR thermal vision is really useful for hunting at night.  We didn't do that though.
