"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." Richard Dawkins
If you disagree with Richard Dawkins on this point. If, when someone harms you, you think that what they've done is “wrong,” then you have good reason to also believe that atheism itself is a bogus world-view. For on atheism, what that person has done, at most, is flout social convention.
"If there are objective values, they make the existence of God more probable than it would have been without them. Thus there exists a defensible argument from morality for the existence of God."
