If an evolutionist sticks to the subject - i.e. evolution - than there is NO REASON to discuss the ultimate origin of life - it is outside evolution's jurisdiction.
If an evolutionist wishes to discuss the ultimate origin of life then they are no longer talking about just evolution.
An evolutionist could just as easily believe that God created and is responsible for evolution and there would be no conflict.
Simple enough?
Now look what you have done. I said the previous post was the last. This one is. :-)
