Thanks for asking,Praline.
Until my mid-twenties I was a bog-standard Christian. Then I saw something on television about Jesus which both puzzled and surprised me. I started reading lots of books about the origins of Christianity and discovered how appallingly ignorant I was of my own religion (as most Christians are). For example, I had had some vague idea that the gospels were eyewitness accounts by four of Jesus's disciples called Matthew, Mark, Luke and John!
As it became clear that nothing was written about Jesus during his suppsed lifetime, that he appears in no records of that time, nor in the writings of contemporary Jewish historians, that there is not one ear- or eyewitness account of anything he said or did and that the (unknown) people who wrote the gospels never knew him, I realised that there is no reason to consider the Jesus story as history, merely as myth. At the same time I recognised that my belief in God was also irrational and built merely on my upbringing. So I became an atheist.
But the subject still interests me (purely academically) and I now have lots of books about the bible in general and the NT in particular.
