If the Universe is
infinite, which can never be ruled out, it must contain infinite possibilities,
in which case the emergence of water or a black hole, like a stream or galaxy, isn't inexplicable but only an event.
To insist the
emergence of a leg or an eye, or of a whole living person, is
inexplicable - that it defies the mathematical odds against - ceases then to be
sustainable.
It simply shows that people cannot yet explain themselves, or rather think too much of themselves, not that human beings are
impossible.
