Also we can show how the eye evolved over time. There is a spectrum of complexity in eyes found in nature. Starting with light sensitive cells to full out telescopic eyes.
Even the simpliest form of photon detection requires a massive and complex amount of DNA. Stop pretending otherwise.
That was actually one of the first things to evolve in single celled organisms actually. Mostly so things could move to or from light. Sight actually evolved with the ability to move.
Doh.. single cell organisms do not have a pit eye. I thought this is obvious. SCO can detect light and react to it - spot. More complex eye on a SCO look up warnowiid
