Thunderstruck, What is life? Are viruses alive? Where is the boundary between living and nonliving? Are thunderstorms alive?
I don't know what the boundaries of life are or when or how it started. That does not really matter to me. What does concern me is the patterns of life, how it works, and how it changes over time. These things will help me understand the past and the present and help me predict the future.
It is not necessary to "prove" how life began in order to understand and learn from the patterns we see in evolutionary theory.
