Want proof that no intelligent designer created us?

A few terms into her undergraduate years, the daughter was convinced that our biochemistry plays a huge role in our physical and mental health.

A year into medical school, she wondered why we just don't drop down dead like crazy.  The human body is a crazy patchwork, she said.

Of course she is correct on both grounds.  Not because she is my daughter ;)  It is a miracle that we humans are still around despite the manner in which our bodies are designed. 

The incremental adaptation over thousands of years means that evolution "constructed our bodies with the biological equivalent of duct tape and lumber scraps."  We are one hell of "a fixer-upper."

My favorite among the top ten design flaws there is about the scrotum.  Because, as a man, I see it and feel it every day ;) "A man’s life-giving organs hang vulnerably outside the body."

Evolution came up with this stupid adjustment to keep the sperm need to be maintained a tad cooler than the body's temperature.  In trying to take care of a problem, evolution does a cost/benefit analysis of a few options--mutations.  What works--the surviving mutation--is the low-cost/high-benefit solution.  The aesthetics of the design be damned.  It is all about the function.

But, the fix is easy for an intelligent designer, if there were one.  Undescended testicles.  Remember this post?  What's good for the mighty elephant ought to be good enough for us meek ones, right?

And then there is the bizarre shape and structure of the penis. 

Seriously, what more proof do you need that no intelligent designer created us humans?

I suppose it will be impossible to have such conversations with the faithful who believe that a god created us.  After all, god's will hath no why!
