I have read "Nailed: Ten Christian Myths That Show Jesus Never Existed at All" by David Fitzgerald and it makes an intersting read.
That the Gospels, the ones the Church allowed to be included (why were the others, known to exist or to have existed, were excluded is one of the many unanswered questions still, after God alone, if he exists, remembers how many years, awaiting a response from the Vatican) contradict each other in matters that are basic tenets of the religion, why there no longer exist any writings about Jesus written while he was, supposedly, alive.
The earliest being at least fifty years after his, supposed, crucifixtion and most that exist from that time writyten by Christians or their apologists.
At least Pagans are willing to own to their beliefs being FAITH not FACT!
