Atheism is unreasonable

[Esquilax]

You ever heard of "organ donation"? That is possible because a few parts of the human body are interchangable, just like auto parts can be interchangable. But regardless of that fact, each part is designed specifically for a certain human and/or automobile.

So how do you explain the numerous flaws and nonsensical design elements of the human body, in the face of this supposed perfect design? Why do my eyes project images upside down, for example? Why are human spinal nerves better suited to a forward facing, quadrupedal gait- say, like our evolutionary predecessors had- than an upright one? Why do we have an extra set of toes that do nothing to help support our weight? Or knees that bend at just the right angle to incite arthritis? Why is there a blind spot in every human eye?

I could keep going, but I think I've made my point. And those are just general human design flaws, I'm not even taking into account all the ones specific to individuals; if the human body is designed so specifically and exactly then why do I have to wear glasses?
