If you think about it, Phil has a point ( although it was crudely made ).
Atheists, if they believe that we are all ultimately a by product of mindless chance and evolution from the primordial slime, and are the result of accidental collision of atoms with no Ultimate Creator giving us moral laws to follow, have to ask themselves is there really and objectively RIGHT or WRONG? GOOD or EVIL?
Or is it simply a societal construct ( and an individual preference )?
In an atheistic worldview, Who decides whether a murderer is REALLY and OBJECTIVELY evil?
An accidental collision of atoms called NAZIs struck down an an accidental collision of atoms called JEWS.... what of it then? It is simply all atoms in the end...
