So, Thunder, what is the boundary of life? Are viruses alive? When is something dead? Give me clear definitions that work all the time in every situation. I don't think you can even though that seems to be a cornerstone of your arguement.
This is all a red herring. Life is definable. Even if you believe there is no distinct boundary (I believe there is a clear definition) you still have clear categories of living vs non-living. You are still faced with the complexity of the simplest free standing life form. This needs to be explained. It can not be.
