As one born to nature, raised in nature, in complete absence of any god talk, I had no concept of any of this shyte until I went to catholic school (our education only became secular in the 80s).
As a young student, there wasn't much talk of religion among students, even tho most did attend Sunday mass. BUT, from grades 1 thru 3, I was in a 'double-class' with two teachers, one being a very authoritarian nun, and she gave me hell on earth, on a daily basis. Of course, to add to this, she knew (even tho I didn't) that I was a bastard child and the school principal, which was also a nun, pushed very very hard for my mother's husband to adopt me legally, which they finally agreed to in grade 2, by which time the school was threatening to expel me for non-religious family compliance!!!!
Throughout elementary and high school, I often said, on religious conversations "well Jesus might have existed and seems 'cool' enough" but I don't buy any of your god crap". But back then I thought that possibly the bible had been written by guys of those early decades and that the Jesus figure was actually known of in those early decades. It was only in my 20s that I found out there was zero archeological evidence or either Jesus or biblical writings from the early decades.
The fact that there is zero evidence for THE Jesus religion refers to IS is of consequence to me, because it is of consequence to us as a nation, because it is a sticking point in religious conversations. When WE waver on such statements, it gives strength to religious zealouts. We atheists need to be firm in our assertion that there is zero evidence of his existence, but I know to many woowoo people who say they don't believe in god, but they give all sorts of leeway to the fairytale that is Jesus. Not only is there zero evidence... but on the issue of someone SO GREAT, surely the early texts would mention him, which they don't, which is even more telling.
