Not really, really. Life started suspiciously early even before this.
This just makes whatever weird conclusion (life is super easy/panspermia
is very active, or we are very lucky but there are some rather unlikely
steps between life and intelligence) a bit more extreme.
I am somewhat sceptical about the claim - they have carbon with the
right isotope concentration for enzymatic life, which IMHO is weak evidence.
