I don't think atheism is better, nor is agnosticism, nor is any other religion. I think people should be free to believe in whatever they like, and no religion is superior to another. Each one, in its own way, contributes a piece of the ultimate Truth. We'll probably never be able to put all the pieces together, but I think it's important to realize that there is a universal Truth out there, whether you want to call it God, Allah, Nirvana, Brahma, is your business. But when you get down to studying religions comparatively, you'll realize how similar they all are in the end, with minor, yet crucial differences, that stem not from the religion itself, but rather from the culture in which the religion evolved.
