Atheists if evolution is based on species survival of the fittest and adaptation, ,?

Evolution only applies to self replicating systems with inheritable traits and variability in the mechanism that transfers the inheritable traits from one generation to the next, and only as long as this system satisfies the Markov property. Before the first organism evolution didn't apply. Abiogenesis doesn't require evolution nor does evolution apply to abiogenesis. At that point all that mattered was chemistry.
