Rod, I'm not sure what you're asking...abiogenesis is implied by the existence of life. Obviously, at some point, there was something that was not alive, and then it became alive. Otherwise all this life wouldn't be here.
Are you trying to suggest that finding life outside of Earth would disprove the existence of God, or something? Because it has no bearing on the existence of God. If there is a God, it designed the laws of physics (including those governing the multiverse, so if there is one, it doesn't change this) in such a way that abiogensis would occur and sentient beings would evolve from lower forms of life on at least one planet, if not multiple planets throughout the universe.
I'm a Deist....but the Roman Catholic Church, at least, teaches that the existence of alien life and alien civilizations does not contradict their beliefs.

Interview with Jesuit Brother Guy Consolmagno
Guy Consolmagno is the current head of the Vatican Observatory. He has a BS in Planetary Science from MIT. Yes, that MIT, where smart people go to school. He also has a Ph.D. in Planetary Science from the University of Arizona. So he knows his stuff about science and about religion. And he says there's no contradiction; alien life and alien civilization is completely in keeping with the teachings of the Roman Catholic Church. Dr. Consolmagno is a Jesuit (part of the Roman Catholic Church). I have deep respect for them because they think about religion in a very intellectual way. And they believe that practicing secular science is a way to worship God. The Vatican Observatory does a lot of secular science...they have helped discover exoplanets, do research in cosmology, etc.
