Evolution does not begin until life has already begun; thus the theory of evolution does not address the ultimate origin of life, nor does it need to. Life's origin is an interesting problem, to be sure, but the theory of evolution does not require its solution.
The simple fact is that "evolution" is not empirical science at all, failing to meet any criteria for empirical science, but is in reality a "religion" of pure conjecture based in blind faith.
I see that you are new to these threads. This point of yours has been addressed countless times. For example:
The Scientific Case for the Theory of Common Descent with Gradual Modification.
Is Evolution Science?
