once upon a time a trilobite developed an indent in it's head and that eventually became an eyeball the end

so, like ... neurons from the brain just like "reached out"

Just google this shit you retard. There are countless articles and videos about how sight evolved more than once and specifically about our eyes.

Probably as some basic rudimentary receptors that can pick up on light and react to it, leading whatever organism to know it was in the presence of light, and then it tippy-toed all the way to perceiving a mental picture based on the volume of light around it, using it as a depth perception. Distinguishing different wavelengths of light probably came later.

So in a single mutation the organism in question spontaneously developed not only emf receptors but the circuitry to hook that up to their brain? If it was done piecemeal instead then how would the tiny changes propagate through the species?

I can tell you are trying really hard to be obtuse.

If you want to argue against evolution please study the underlying mathematical frameworks before hand so you can understand how stochastic processes intersect with emergent systems.

In short though, yes. You can even trace the development of vision through extant organisms who have varying levels of receptivity to light. From bacteria with a protein that reacts to the presence of certain light giving a small gradient to light spots which release signalling molecules in the presence of light to the attachment of naive neural nets connected to specific motor responses in invertebrates to eventually developing more complex transparent shields to protect light spots that would make a nice gradient towards the formation of a lens.
