I think she was just being hyperbolic. Wan asked her about her winning the next harmonic convergence if Vaatu succeeds in the current one, and Raava responded that humanity wouldn't live to see it because darkness would cover the human and spirit worlds for 10,000 years. "Ceasing to exist" in this context likely means both worlds being unrecognizable when the next HC comes. Though... It is possible that, given how reactive the Spirit world is too energy, it's possible that the spirit world could get ****** up enough by Vaatu's chaos that it could be irreparably damaged and disappear, and that this would affect the human world in turn. Though that wouldn't really be an ap feat.If we take this literally as Raava suggested, Vaatu would be implied to be capable of destroying both the human and spirit worlds entirely.
