So your an Athiest

[God of Mr. Hanky]

The facts: organisms can sense light. We have organs that sense light.

Your interpretation: one must have become the other over many generations.

If you are going to butcher my statements so mercilessly as that (which, btw, is the mark of the truly desperate), then I'm not even going to address what you hand back to me - go read it again!

You have been taught in your biology class about the slight changes that occur, and they tell you that these changes can lead to entire new genetic information. Evolution operates by changing existing DNA. It has no good mechanism of adding new genetic information.

That line of bullshit is in dire need of empirical evidence regarding both its accuracy and relevance!

The design of the human body is amazing. If there was an engineer alive today capable of designing something that efficient, they would be the most successful engineer of all time. The appendix still serves functions. It has functions in cultivating bacteria for your intestine to aid in digestion. It also may have immune functions. Life is not poorly designed. 

Just keep on telling yourself that enough times, and maybe sooner or later you'll believe it yourself. You can't really believe it now, otherwise you wouldn't need the affirmation of coming here to say it.

The simplest cell is more efficient and complex than anything mankind has done.

So fucking what? "Mankind", which is no word used by scientists since the Christians no longer controlled them, doesn't claim to be a designer of life forms which evolved over billions of years - therefore, ZERO points again for your creator gabble. We are very, very complex life forms, but complex <> flawless. I'll bet you skipped out on your mathematical logic lessons.

The cones of your retinas are not perfectly designed for efficiency, even if you see 20/20 because they face backward. It took further evolutionary development to form an end run around this defect.

We are designing life right now, and if demand supports it, science will eventually rival the complexity of human perceptions and thought, and probably with fewer defects. To actually imitate life as it exists today would be very difficult, not because it's so awesome and flawless, but for the very good reason that life was never engineered in the top-down fashion which is required of short-lived human engineers. Be honest about this, if you are capable of doing so: just why in fuck do you really think your god would sit back and watch everything that ever crawled out of the dirt blunder and waste so much time over the past 4 billion years, bandaid-patching one defect at a time and changing so slowly that between adjoining generations they are barely noticeable at all, when he actually had a plan? No, Genius, plans do not work that way. Go ahead and chalk that up to "mysterious ways", but if your god did that than he's an asshat.
