I was extremely doubtful about the idea of god, but I just didn't know enough about anything to have a good working model of any other explanation for, well, life, the universe and everything to put in its place...I stumbled upon evolutionary biology .. and suddenly it all fell into place. It was a concept of such stunning simplicity, but it gave rise, naturally, to all the infinite and baffling complexity of life. The awe it inspired in me made the awe that people talk about in respect of religious experience seem, frankly, silly beside it. I'd take the awe of understanding over the awe of ignorance any day.
