And so it begins...
"I don't know that there is much debate over whether or not a man named Jesus of Nazareth actually existed, despite the little recorded evidence outside the Bible"
so you have no facts to present and admit there is no evidence outside the bible but you fordge ahead and accept as fact the jesus was a genuine historical figure.
"For such a shift in consciousness to have occurred so suddenly within one generation would suggest something real took place."
Really? Why is that? Culture shifts all the time.
"You can debate whether or not this thing has any real meaning or significance to you or humanity but I think it's pretty evident that something real actually did happen"
And now the crux of your argument.. "Pretty evident"? Ahh yes that word proof has now been disregarded totally. "Pretty evident" is classic weasel words in action. Pretty evident means no actual evidence at all but you want it to be true so you assume it to be so... thats not evidence of anything.
