It's difficult for me to understand how one could take a position about whether or not there is a God...
One need not disprove something when it's sufficient to merely not accept it.
There are lots of things I don't accept. For instance, I don't like schmaltzy lyrics in any genre of music. However, I'm not about to take a PhD in English with a dissertation on poetics for the sole purpose of intellectually justifying to someone else My dislike of a particular tune.
Similarly, as I seem to have been born with a congenital inability to cultivate any sort of religious faith, I don't accept the idea of gods that must be accepted sight unseen. I can accept gods as metaphors and symbols, and I can accept the hypothesis that there may be beings more powerful than humans somewhere in this vast universe, but the idea of an eternally existing but completely undetectable entity of immense power? Absurd. That falls squarely in the category of "I'll believe it when I see it, and not before."
