The sad thing is, all the gullible people will believe one or the other.
I was having a chat the other day with a Jewish atheist who was asked by a Buddhist if the virgin birth was central Christianity, that is, if you had to believe in the virgin birth to be a Christian.
Without going into details, the Christ figure had to manufactured so as to make true, so called prophecies contained with the Old Testament in order to be the Messiah. Being born of a virgin isn't one of them. But, it was very popular at the time (being born of a virgin) so I've always put it down to the norm. to be expected for marketing reasons etc. Turns out there was no mention of it at all for quite a considerable time after the death of the Jesus figure (though not a word about it in Mark which is the earliest of the gospels) which could indicate that it was added by way of the other 3 gospels. Further to that, it was well known that the Jesus figure had said he would return within the lifetime of some of those who knew him, how long would people continue to believe after the figurehead had died until they realized that nobody could still be alive? (say 100 years). Perhaps people were falling away from Christianity so it needed to be 'sexed up'.
The reason I mention this is just like the gullible people will indeed continue to believe one or the other because it is not a central tenet of their faith.
