What Driven Your Atheism?

Prior to that first year at cambridge, what what would you have said your believ i was an atheist. My fater, my father, was an agnostic. But i became an atheist in my teens. I just threw through a kind of, i guess, sort of home made philosophy. Sortof felt i'd found the answer to er the possibility of there being a god. And i became quite an argumentative atheist,. which i was for the first, my first term at cambridge.
