The first attempt at an American Godzilla film, GODZILLA 3D played on the idea that Godzilla was from a stage of evolution that predated even the dinosaurs. That it was a type of proto-saur, a giant creature that could survive nuclear radiation and even expell atomic flame. Not too much different from showa Gamera's origins.
I think that as an explenation for how creatures like Godzilla and Muto could exist-- will be that they predate even the dinosaurs and therapsids. Hell, Godzilla might even be a therapsid, explaining why he has such mammalian features.
So I'm assuming Godzilla is not only able to survive nuclear radiation, but possibly feed off of it. Perhaps his species went into hibernation at the end of the precambrian era, as the Earth's enviroment became more suitable for other forms of life and didn't wake up again until we started playing with atomic power.
Just food for thought-- I have a sinking suspicion Godzilla's entire origin will not be revealed in just one film and I'd kind of like it that way.
