Extraterrestrials

<p>

The events on earth that led the emergence of life either were an arbitrary creation event (in which case there’s no reason why they should or shouldn’t have happened elsewhere), were based on as-yet unknown science (in which case there’s no grounds for making assumptions about them), or were the result of such a unlikely coincidence that the odds are very small that they happened anywhere else, even given the imminse size of the galaxy.

How do you know how unlikely or arbitrary it was?</p>
