The best I have is that many people simply want to believe there is a higher power. Sure upon examination most theories can be broken down and disproved, but they can't be 100% falsified because no one really knows the truth about a gods existence until death. Of course by that point it's already to late to provide a definitive answer to the world. I personally believe in God and respect your opinions on the matter, and my opinion is to live your own life and I'll live mine believing what we each choose to.
