OK, but there are ramifications in assuming naturalism – and again, that is the point…
In a universe of blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won’t find any rhyme or reason in it, nor any justice. The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind pitiless indifference.

The alternative is to assume supernaturalism, which would not make sense since there's no evidence for anything supernatural.
