How about just using the definition: Decent from a common ancestor. Thats what the debate is about, that is what this thread is about, not the watered down bait and switch that Darwinists like to use when convenient.
OK. Let's assume that's a good definition.
How does that definition encapsulate the start of life? Where does it address the creation of the initial ancestor?
It doesn't. It says nothing about it. Ergo, claiming that evolutionists MUST be athiest and cannot believe in God or creation or Intelligent Design falls flat on its face.
By your own proferred definition, we are talking STRICTLY ABOUT THE PROCESS, not the beginning, no?
