I kind of wonder if we shouldn't be breaking the definition down into substeps rather than try to lump (essentially) the whole abiogenesis process into a single definition.
Totally agree. After all, stellar evolution plays an essential role in abiogenesis. Even though they're only 2-3 generations old, I have always felt that stars have to be included someway along the non-life--->life spectrum.
This is one of the reasons I think a multilevel definition can serve better
