Yet you made an argument as if the points in it had never been made. If you read it, you just made your standard reply.
The author attempts to build his case strictly on biblical sources
And there's nothing wrong with that.
none of the writers of the New Testament were even alive at the time that Jesus allegedly lived.
Any proof of that?
Certainly someone who had done as much as Jesus did would have earned at least a footnote in non-biblical sources besides the passing reference made by Josephus.
That's an unwarrented asumption.
Pagan resurrecting god/men were common mythical characters dating to Sumerian times. There is no "historical fact" known about Jesus Christ that was not a part of some previous pagan myth. All the miracles, parables, and important events of the gospels are from stories told of previous god/men.
The Christian sect of Judaism was the creation of educated Alexandrian Jews who were steeped in the culture of the Greeks. They melded a popular Pagan Resurrecting god/man myth with the Jewish Messiah concept. The Jews for the most part weren't interested because they wanted their Messiah to be a military conqueror not a spiritual savior. Instead, Christianity found its most enthusiastic followers from among the uneducated slaves and disenfranchised commoners of Rome. The rise of literalist scriptural Christianity was attended in large measure by roving mobs of ignorant fanatical zealots whose primary task was the practically complete destruction of Pagan civilization. They also destroyed Gnostic Christianity in the process. You may have recently noticed that this is the characteristic attitude of certain present day religious fanatics toward Western Civilization.
