Evolution does not have anything to do with the origin of life, that would be abiogenesis. There are many different ideas as to how the first cell evolved, and it is one of those questions that is too complex to answer at this time.

The Miller-Urey experiment is the only real information we have. Amino acids found in living cells were formed by the carbon and other elements that likely existed in early Earth.

Maybe we are aliens. Who knows.
