Yes, that is what this thread is about.
I mean, if we are what we are today as a result of a development that eventually led to this outcome, even if it was a pure result of chance and chaos, then wouldn't we, looking back at this development see a sting of events that gradually opened up the possibility of our existence?
I can understand how a person who puts too much importance on human existence would mistake this as evidence of a purpose that we are the fullfillment of.
The way I see it, this planet wasn't changed into something that can support life so that life could come into existence. That's rather backwards.
Instead, I think that when this planet altered into a place where life could be sustained, a possibility opened; the possibility of life. And then it happened, just because it could. And just because the oportunity was present, it evolved until it was what it is today. Looking back at that, and not thinking in terms of oportunity, but in terms of purpose, I can understand how it may seem that our coming into existence was part of a great scheme. I can see how some may believe that, but I don't believe it myself.
