No religion endorse it.

None that John Larkin can understand. In fact all life depends on a 
couple of RNA based enzymes, and they probably have been there from the 
start. Some viruses are RNA only. DNA offers a more stable genome, but 
there aren't any DNA based enzymes. John Larkin is arguing from 
ignorance, and he's got a lot of ignorance to draw on.

Sadly. John Larkin isn't all that complicated. Push the right button and 
you get the same half-baked response every time.

A better education might have provided a greater variety of responses, 
but he still hasn't got a patent of his own.
