Hypotheses of abiogenesis are absolutely NOT part of evolution. There may be abiogenesis hypotheses in biology books because that is the explanation science has to offer. These, unlike evolution, are not theories, however, but hypotheses. The idea that God created the first life forms is outside the realm of science. Even if God did create the first life forms, it causes absolutely no problems for the theory of evolution, which only describes what happened to life after it began.
