Is there any broader significance to the ability of individual bacteria to survive, potentially, for 250 million years? In a word, yes.
If bacteria really can survive in stasis for millions of years, we cannot rule out the possibility that cells or DNA first arose on another planet in another solar system – even in a different galaxy – and then travelled to Earth on a comet or asteroid. After all, the nearest neighbouring galaxy to our Milky Way is the Andromeda galaxy, which is only 2-3 million light years away: an approachable distance for a bacterium that can survive for 250 million years.
