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. <br>

I am somewhat sceptical about the claim - they have carbon with the
right isotope concentration for enzymatic life, which IMHO is weak
evidence.<br>
