...I cannot accept evolution because the human body is too complex to have come about by the mechanisms of the modern synthesis
And you know this how, exactly?
What I am saying is Neo-Darwinism doesn't seem an adequate explanation for complexity.
And then instead of providing evidence supporting a competing theory, you accept a false dichotomy where your favorite belief is the only likely alternative. To borrow a phrase from James Randi: flimsy and quite transparent.
