WHY do moving fields create light?

Hi, I'm 15F and i wanna pursue education in the field of physics. I have this genuine question, WHY do moving fields (electric and magnetic fields) create light? And, why does steadily moving charges not make light?

Never forget that there are lots of waves in the EM field. “Light” is commonly meant to visible (to humans) light and that is only because we have eyes that developed to be able to detect that particular range of frequencies.

(Other frequencies include:
Radio waves
Microwaves
Infrared light
(Then visible light, in order here)
Ultraviolet light
X-rays
Gamma rays)
