If you’re suggesting that is what evolution implies, it is through some unwritten, unspoken rule only. As I said there are offshoots and misuses of the theory, sometimes by atheists to promulgate their Godless philosophies. Darwin himself believed in God, however, and was not a Social Darwinist or a Humanist by the definition many of them go by. If life itself is an accident, what does that even mean? Or does it mean that only God knows? Don’t we often call accidents an ‘act of God’?
“Act of God” refers to an event for which there is no human explanation. Let me say that it IS no accident that cruel business practices and other assorted acts of man’s inhumanity to man were labeled “social Darwinism”. The shoe fit.
My guess is that Darwin claimed to believe in God to assuage people’s faith concerns during that era. To not have dealt with the question and speculation of God’s role leads me to believe that he was a closet atheist. He did state that he suspected the tiniest building blocks of life must be simple stuff-—or else his entire theory would fall apart. Now, if he was truly a believer in some sort of Creation, the intricacy of the “simple” “stuff” would not have concerned him.
