A great ad aired during this year’s Super Bowl. It was a surprising ode to atheism, in which the spirits of discovery and wonder were paid their dues.How refreshing to see free thinkers band together and promote the pursuit of knowledge. It is about time common sense got its share of airtime.Before I go on, let me say that I am not an atheist. I believe in something divine, a force of some kind that encompasses life in mysterious ways. Be it God or consciousness or aliens writing computer simulations of which we are part, it matters little. I cannot prove it, so I don’t even try. But I believe in it, because I have felt its presence in my life.
