Both are theories in the real sense. The thing is, we only know so much. When I studied Solar System Astrophysics many years ago, Pluto was still considered a planet, and Jupiter now has a bunch more identified moons. We are still learning as we go. I'm not going to be here in 4 or so BY when whatever happens, happens.
