First of all there are very few intellectual public figures in the first place that believe in the Jesus story in the first place.
Believing Jewish stories written on Hebrew Scriptures about Jewish people that far predates Christianity is beyond ridiculous.
Even some of the founders of Jesuit were Jewish, and some of the Jesuits also are fully aware of the Jesus story being plagiarized.
Justin Martyr, one of the first Christian historians and defenders, wrote:
"When we say that he, Jesus Christ, our teacher, was produced without sexual union, was crucified and died, and rose again, and ascended into Heaven, we propound nothing different from what you believe regarding those who you esteem Sons of Jupiter."
In a different writing, Justin Martyr said
"He was born of a virgin, accept this in common with what you believe of Perseus."
It's obvious that Justin and other early Christians knew how similar Christianity was to the Pagan religions. However, Justin had a solution. As far as he was concerned, the Devil did it. The Devil had the foresight to come before Christ, and create these characteristics in the Pagan world.
The ''debunkers'' seem to primarily focus on small details, such as the difference between ''12 brothers'' and ''12 messiahs'' or birth/death/resurrection sequences, along with who Peter Joseph sources.
Anybody who has even touched Egyptology, let alone extensively researched it can tell you that there are clear similarities between Egyptian mythology & Christianity.
Spell 125 of the Egyptian Book of the Dead.
And so on and so forth.
They can also be found on the walls of Luxor
And many, many others.
So is there nobody else that fits the bill of Jesus Christ?
The parallels go on and on.
The Bible is nothing more than an astro-theological literary fold hybrid, just like nearly all religious myths before it. Christianity is simply not based on the truth.
