It seems likely simply because life came into existence almost as soon as physically possible on earth.

It seems likely simply because life came into existence almost as soon as physically possible on earth.
- abecedarius 5y agoSuppose that life starting is one out of multiple hard steps needed for us to exist. And there's a deadline of perhaps a billion more years before we could never exist, if we didn't occur by then. Then the early appearance of life is not evidence that life happens easily: all of the hard steps have to happen 'quickly' relative to how long they would 'naturally' take, or we wouldn't exist to observe this history. I think the paper explains this logic, going by the abstract.
