We have no idea of what the boundary conditions are, or where they are, or on what scales they may exist. They may be tiny, or they could be huge.
The self-similar system from which life emerged, could quite well be defined by the infinite, (ie: unbounded), boundaries of the universe. This would mean that the universe needs to be as big as it is, for one life pattern to emerge, or for many multiple instances of life patterns to emerge. We just don't know.
Chaos theory and fractal geometry doesn't really help us in this respect.
The only scientifically, (or statistically), supportable statement is that the possibility of life emerging elsewhere, is entirely unpredictable. (So no statistics, or probability justifications hold anything of value, veracity and hence, meaning).
