"There is a next to infinitesimal chance that life started very quickly by some kind of once in billions of years magical circumstance."

Tautology? There is a very small chance that something with a very small chance of happening happened...

[inimino]

The intended meaning was that there's a small chance of something unlikely happening quickly. If it happened "quickly" (in geologic time) once conditions were favorable, that is evidence against it being enormously unlikely once those conditions obtained.
