I'm not sure about that time-frame, but in about a half million
years, there is supposedly a high-velocity star that will pass within a
light year of us, ejecting thousands of Oort objects into the inner
solar system, some of which will strike earth and liquefy its
crust.

So we don't even need to wait the 8 billion years before the
Sun goes Red Giant.
