Possibilities for methanogenic and acetogenic life in molecular cloud The author says that these molecular clouds could sustain life in the form of methanogenic bacteria. There is enough carbon monoxide, carbon dioxide, and hydrogen in the clouds to keep the bacteria alive. The paper does not explain, however, how this life came about in the first place.

Life Could Have Begun in an Interstellar Dust Cloud

IMO this theory has bit of truth in the matter that particles of interstellar gas can mediate DNA and RNA fragments from planet to planet and to speed-up/modulate their life evolution in this way. See also:
