Hi,
I think I have another way to determine when a complex(rare) event implies a creator.
When the event is not necessary to the existence of the observer, one would perceive it in its true frequency. So if it happens too frequently, one can say it was designed. (ex.: arrowhead complexity)
But when the event is necessary to the existence of the observer, one would perceive it as being more frequent than it actually is. So, even rare, random events would seem frequent when they happen. And, in this case, one can not tell if it was designed. (ex: DNA complexity)
sorry for the english (im not from Bagdah)
