I understand the concept you hold to. It doesn't matter that I don't adhere to it, by that I mean that the theory of life coming from non-life is absolutely essential to comprehend well the theory of evolution. because without the recognition, and confirmation not by experiment of combining elements with electric currents imposed that evolution by "natural selection" happened to happen from nonliving matter, the theory/concept of evolution could not happen. Similar to the idea that I do not agree that humans are in the ape category. You may believe that, others may believe that; I do not. I mean wasn't it Kafka that wrote something about a character becoming a roach or something like that? Not sure, but it suddenly recalled to my mind. Metamorphosis I believe the story was called. Not gradual.
