Here's another supernaturalist alternative to natural abiogenesis.
First we assume Vitalism - that there is a "life energy" apart from matter, and it is this animating principle which is the true nature of life..
Then we assume that there are sparks of "life energy" drifiting around the universe and that they have an organising effect matter they encounter If a spark encounters sufficient matter of the right sort it produces a vehicle for itself which it enters and animates.
Thus we do not have true abiogenesis (life exists apart from matter) but we do not have creation by a mind either.
