Defiance, honestly, no one has ever proven the existence of God. On a forum, on TV, via debate...you know it hasn't happened. Their evidence is their beliefs, often the number of their followers (though they argue internally who truly is a representative), and sometimes their books. That is all they have and will likely ever have. I don't think the majors will ever go away, people will still always want to believe that there's more than us out there, somebody superior to offer us a better existence. I just hope that eventually millions of those who want to slaughter others in the name of their god would look to the past and see that the rest of us have left that stuff behind years ago. Time to get with the reality of living on earth with others who don't believe what you do.
