Got to side with you, Slevesque, here. I cannot see the point of this argument. Using abiogenesis in a non-naturalistic sense is simply confusing and is the non-creationist way of getting back at creationist bullshit regarding the word evolution (cosmological, chemical, etc.)
If a creationist states that abiogenesis is impossible, it's utterly counterproductive to retort with "well, how did God make people then?" The response should be - "so, what you are saying is that you don't believe that life can naturally arise from what we would consider non-living material."
If it really is the case that naturalistic means cannot* bring about life, that in no way stops the great djinn from popping a rabbit into existence by twitching its nose.
* I have to say that to me it so damn obvious that life will arise from the correct natural conditions, that I find it hard writing that conditional clause!
