I have to admit that there is a part of me that would be thrilled if there really was (in the words of James Russell Lowell in The First Snowfall..) a "good All-father who cares for us here below" and this would probably affect my perceptions of life and its meaning.
I do think an important distinction might have been unclear in this thread and that is the difference between organic evolution and social evolution. Not everyone accepts the former, but there really is no question about the latter. As the human race grew, our moral sense had to grow with it and this is apparent even in the Bible in the progression from a primitive, "eye for an eye" mentality into more productive forms of justice.
