OK. Where do I start!!
A)I think the evidence for the Bible Jesus being a fabricated story is overwelming! It is a fact, that nearly every major event in his life -as reported in the Bible - mirror events in the lives of earlier God/Men; And to those I listed 23 June 01.25pm a lot more can be added e.g. the King ( Herod in the Bible ) who tries to have the baby god/child killed by the slaughter of the innocence is found in many pre-Christian myths.
B) This idea that the existance of there pre-Christian god/men with a similar profile to Jesus is common knowledge among your average Christian is nonsense! A year ago I was talking to a group of Catholic teachers, one of whom had studied the early- Christian Church at college( a Catholic College ), and they were flabergasted at the parallel lives of Jesus and the pre-Christian god/men. If this educated Catholics were ignorant of such connections, I'm pretty sure your average Christian Church-goer is even more in the dark. It is not in the Catholic Church's interest to encourage its members to start asking questions.
C) And by the way Wolfgang, you are not an atheist!
