"DNA had to sponteneously emerge somewhere"

No, it didn't. You can start with much simpler RNA and DNA can evolve later once life has got started. Or it could be started by something even simpler perhaps, which no longer exists because it's died out completely, or it is from another planet.

But we're all just guessing so far.
