The question that comes to my mind is how would the light taken in by the "light sensitive patches of skin" penetrate through a skull with no openings, eye sockets.
Because it evolved long before skulls. There are primitive light sensing mechanisms in single celled protozoa. Vertebrate evolution is comparatively recent.
A thought! possibly non-vertbrae animals, such as earthworms would be sensive to light, my flashlight when I'm looking for bait!
I don't know what that sentence means. But yes, invertebrates do have a variety of different eye types. For a chart of invertebrate eye evolution, see below.

But an earthworm and I most definately do not share any ancestors, cousins nor in-laws.
Most definitely? If you say so, but science indicates otherwise.
you know, it's all just such a far stretch of little reason and a whole lot of faith to believe in evolution.
So if I get this right, your entire argument is "I can't wrap my mind around evolution -- it's just too complicated for me to understand -- therefore it is implausible." An argument from incredulity is not an argument.
Hey! It's cartoon Saturday!
