The brain doesn't look like a design? Working parts placed in order to achieve a goal? That's not a design? Why am I in here arguing this, OMG. This is ridiculous. If a keyboard and computer monitor are "designs", then how is the human body not a design? I'm so confused as to how you can't see this, it's rather blowing my mind...
Please watch the video I posted for your benefit. The human body is not intelligently designed. We eat drink and breathe through the same hole, guaranteeing a risk of choking to death. We reproduce with organs placed in the same area as our waste disposal system. People can be born with and afflicted by an incredible variety of ailments and defects. My ex brother in law has agammaglobulinemia. This means, according to your worldview, that he was born (DESIGNED) such that his body is not naturally able to produce an immune response. Note that this is not a minor and easily correctable defect. This makes him very susceptible to illness, and even the slightest infection could kill him. He was recently diagnosed with Hodgkins Lymphoma (was that intelligently designed too?).
Others are born with things such as microcephaly, a condition in which the brain is significantly diminished in mass, and therefore function. Such individuals have very little chance of ever functioning at a normal level, and are often incapable of speech, have poor coordination, and have very limited learning potential. Is this an example of intelligent design?
Some people are born with other, less immediately recognizable mental defects, that lead to schizophrenia, sociopathic behavior, dissociative identity disorder, etc. Is that Intelligent Design?
Some people are born missing organs or limbs entirely. There are twins born fused together, and only medical science can remedy it. Is that Intelligent Design?
If the human body was designed, the designer was far from intelligent, and indeed, appears to be incompetent.
