I have a hypothetical question.  If, given that life formed quickly,
the obvious conclusion is that the probability of forming life is
very high, what would the obvious conclusion be if we discovered
that life appeared to have formed even more quickly, say,
instantaneously?

     This is likely to remain a hypothetical question given what 
"instantaneously" means in the geologic record, especially for events
that occurred billions of years ago.  Even so . . .
The obvious explanation would be that life originated elsewhere and was
introduced (deliberately or through natural processes) to the Earth.
More than that it would be impossible to say.  It doesn't seem to me that
our ignorance of the circumstances would be a plausible reason for declaring
it a miracle.  Of course, one might choose, as a matter of *faith*, to 
believe it to be one.

In the geological record, 'instantaneously' is still going to be
a very long time in human terms, tens of millions of years at the
least.  Besides, the hypothetical is contrary to the evidence.  The
first evidence for life is at least some half billion years after 
the formation of the Earth.

I have a hypothetical question.  If, given that thought takes time,
the obvious conclusion is that the probability of stupid responses is
very high if they are formed quickly, what would the obvious
conclusion be if we discovered that the response above appeared
to have formed even more quickly, say, instantaneously?

That's only because the Earth remelted shortly after it formed, so that the
surface was liquid rock until ~3.8 billion years ago.  In any case, the
re-invention of life would not be possible now because of this extremely
reactive chemical known as oxygen, and other environmental reasons.

Of course, it still could have taken life 100 million years to form.

On the other hand, life was all single-celled animals and algal mats until
the Cambrian explosion, so it took ~3 billion years for complex life to
evolve.

My question was serious, and I asked it for a purpose.  There
were two serious replies to it (those of Bill Jefferys and Ethan
Vishniac), which I appreciate.

The third response (above) is not very meaningful, helpful, or
instructive.
