Of course there is a scientific explanation for life. Essentialy is self-replicating molecules, it is just physic and chemistry in the end. and scientists can understand how it works, that is how you get things like genetic and cloning and ... uh.. . nanomachines, I guess? Anyway, my point is, life is not 'magic' (except in the Pratchett's sense of "It doesn't stop being magic just because you know how it works.")
Reynard, Coyote and others like them OTOH make no sense. Reynard is a puppet that move, talk and can turn into a wolf.Where does he get his energy? Wheere do he keep his brain? WHERE DOES THE HELL GET (and where it goes) THE EXTRA MASS? That's cheating, I tell you. CHEATING!
Really, i understand why the Court would be pissed.
You can mix all the chemicals you like together but you don't get life.
Did you know that all life on earth is descended from one single monocellular organism?
