Firstly we know that life does come from non-life. Example: Life on earth. At one point there was no life, and then through abiogenesis life began. Once life began a process we call evolution caused single cells to become billions. The evidence for both of these things is overwhelming and beyond a reasonable doubt. There is no logical fallacy to say life cannot come from non-life, as it has happened at least once as an observable fact. As to the actual mechanism involved, you would need to consult a biologist. I'm a physicist. The reason biologists blow you off, is because you refuse to accept their explanations. That makes you a dumbass, dumbass.
