I hope you're referring to global warming as the 'inconclusive' argument. I am completely confident we all evolved from basic, primitive life forms over time and to the shaping factors of climate, nature and opportunity.
Where the essence of life comes from.. we can all have our very own religious convictions if we like. Life could have ridden an asteroid here from very far away. Or God could have had a week where he was extremely bored AND creative... it's pretty much academic at that point however, I am duly convinced that billions of us and our actions have heated up a finite space and caused a daisy chain of change that we are ill prepared to deal with, especially since half of the population still have their heads up their asses.
My point was to draw a parallel between ignorance and the advance of scientific confirmation. At a certain point, the point we are at right now, it becomes a weak man's game to deny... I would hope people everywhere are slowly(quickly), scientifically, mathematically being convinced that AGW is very real, very dangerous and, quite obvious.
I assume you believe in evolution because we've recently been handed a roadmap to it's world and history. We already possessed the compass and now...we are on the road not taken...
