evolutionists will tell you the progenitor of the eye arose only once

I showed you Euglena, an extanct bacterial like animal/plant with an eye. Kindly explain the descent to or from that eye - if you can!

And the genes coding for that eye-spot (not true eye, as you keep saying) would be similar to that coding for the eye in other animals. In other words, to make it simple for you who cannot actually put on the evo hat, we should be able to look at the genes encoding the eye in human beings and that encoding the eye-spot in a single-celled critter and see that, while the human gene is quite a bit more complicated, the basic gene from the single-celled critter can still be discerned. Descent with modification and all that.
