Are you saying there is a chance of such an event?.
No, but he seems to be, which is why I want to see his math. As far as I know, what he's talking about is impossible, which is why I thought it was an inappropriate anaolgy to describe an unlikely but possible event - spontaneous formation of polypeptides.
If I told you that "the odds of you getting three heads in a row on coin tosses is the same as you flapping your arms and being able to fly", wouldn't you say I was wrong? Hell, I've gotten three heads in a row plenty of times. I've never flown by flapping my arms. It doesn't make sense to compare a possible event to an impossible one.
